The I-70
Killer
An Unsolved Serial Killer Case in 2026
K-W-Q-T-R: What Do I Know?
- In spring 1992, six people were shot and killed in small shops.
- The shops were near Interstate 70 in Indiana, Kansas and Missouri.
- A .22 pistol was used.
- No one has been arrested. There is a reward.
- Who the victims were.
- How police linked the crimes.
- Who was suspected, and who was ruled out.
- What evidence still exists.
- Whether 2026 technology could help.
- Why did the killings stop after about a month?
- Why those shops?
- Did the killer leave DNA or prints?
- Why has no one been caught in over 30 years?
K-W-Q-T-R: What Do I Know?
Initial theory, not fact
- The killer may have been a driver who traveled along the highway.
- He may have picked shops with one worker and little security.
- He may have stopped because he was jailed, died or moved.
These are guesses from what I know today. I will test them in my research.
- Forensic science: Bullets and shell casings tied crimes in three states together. Evidence kept since 1992 can now be tested with newer DNA methods.
- The families: Six families have waited more than 30 years for answers.
- The public: The killer may still be alive. Tips are still being asked for.
The Case at a Glance
people killed
crime scenes
states: IN, KS, MO
days, Apr. 8 to May 7, 1992
One unidentified man. Ballistics linked all six killings to the same gun. No one has been named, arrested or charged.
$25,000 from St. Charles (MO) Police for information leading to an arrest and conviction. Last reported as current in Aug. 2025.
Where It Happened

Indianapolis, IN. First attack, on the Far Eastside.
Wichita, KS. 685 miles away, three days later.
Terre Haute, IN. Just north of I-70.
St. Charles, MO. Near St. Louis.
Raytown, MO. Kansas City area.
The Victims (1 of 2)
Robin Fuldauer, 26
Manager of a Payless ShoeSource on Pendleton Pike. She was working alone because a coworker called out.
Patricia Magers, 32
Owner of La Bride d'Elegance bridal shop. One newspaper printed her age as 33, but most sources say 32.
Patricia Smith, 23
A bridal consultant at the shop and a Wichita State nursing student. The two women were killed together.
The Victims (2 of 2)
Michael "Mick" McCown, 40
Worked at Sylvia's Ceramics, named for his mother. He was the only man killed.
Nancy Kitzmiller, 24
Worked alone at Boot Village. She loved maps and was close to a job with the Defense Mapping Agency.
Sarah Blessing, 37
Co-owner of The Store of Many Colors, a shop opened about three weeks earlier. She was working alone.
Suspected, Not Confirmed
- Mary Ann Glasscock, 51, Fort Worth, Sept. 25, 1993
- Amy Vess, 21 or 22 (sources differ), Arlington, Nov. 1, 1993
- Vicki Webb, 35, Houston, Jan. 15, 1994. She survived.
The shootings used a .22, but ballistics did not match the I-70 gun. Police are reportedly split on the link.
Store clerk Billy Brossman was shot in a store seven blocks from Sylvia's Ceramics.
Terre Haute police confirmed similarities and have a person of interest who is not in custody. They are examining it separately and have drawn no conclusions.
Why Investigators Link Them
All six killings were positively matched. The gun was a .22, possibly an Erma Werke ET22 or an Intratec Scorpion. The ammo was CCI .22 long rifle.
Small specialty shops in strip malls near interstate exits. Most victims worked alone, mostly women. Wichita had two employees.
Shot in the head. Victims were moved to back rooms. Only small amounts of cash taken. No sexual assaults.
McCown: Police think the killer may have mistaken him for a woman. He had long hair, and the shop was named "Sylvia's."
How it was found: A St. Charles detective matched his bullets to the Indianapolis case. That exposed the multi-state link.
How Close Is It to Solved?
Never publicly. The nearest moments were the 2021 task force and the 2022 DNA tests. The first results had no definitive findings.
No one has been publicly identified as the killer. Several people were looked at and are covered next.
Arrested: none.
Charged: none.
A person being investigated is not guilty.
Yes. Past examples include Donald Waterhouse and a man tied to a 2001 Terre Haute case. Details on the next slides.
In Nov. 2021, about two dozen detectives from five agencies, plus FBI and ATF, met in St. Charles to share files and re-test evidence.
Evidence: Used and Missing
- Ballistics from shell casings and bullets tied all six crimes together.
- Witness descriptions led to composite sketches, then age-enhanced ones in 2021.
- FBI profiles guessed at his age, job and home base.
- Touch DNA tests on old evidence began in 2021 and 2022.
- 1992 DNA testing was limited. Police said in 2012 there was no sexual crime and no usable prints.
- DNA tests so far have not produced a match.
- Few witnesses and no getaway car.
- Five agencies in three states, with no shared task force until 2021.
- Thousands of names and false confessions.
People Investigators Considered
Donald Waterhouse
Who: A fugitive in spring 1992. His parents were shot in Tennessee about a month before.
Why considered: A composite sketch resembled him, and the timing fit.
Evidence for: Sketch resemblance only.
Against: KMOV reports he was cleared (it says 2012). Wikipedia cites height, age and hair differences. Sources differ.
Arrested for I-70: No. Eliminated: Reportedly yes.
Harry Edward Greenwell
Who: The "I-65 killer." DNA tied him to three motel killings in Indiana and Kentucky (1987 to 1990). He died in 2013.
Why considered: In 2022 a St. Charles detective said the time frame was hard to ignore and the sketches resembled him.
Against: That killer robbed and assaulted women. He was about 47 in 1992. The detective called it "preliminary."
Arrested for I-70: No. Eliminated: Not confirmed or ruled out.
More Names and Claims
Randall Bishop
Who: An Indiana truck driver who matched the composite.
For: The sketch match.
Against: The FBI questioned him in 2001. His DNA reportedly did not match (one source).
Arrested: No. Eliminated: Reportedly yes.
Unnamed 2001 man
Who: A man living in Missouri, tied to the Terre Haute killing of Billy Brossman.
For: Security video. Two people who knew him were "nearly certain" it was him.
Against: His DNA did not match. Police say the link to I-70 is unknown.
Arrested: No. Eliminated: Not officially.
"Joe" (2026 claim)
Unconfirmed
Who: An unnamed man. Reporter Bob Cyphers said on a podcast that police told him he was a suspect. He reportedly said "Charge me or I'm out of here."
Evidence: None public. Police have not confirmed it.
Arrested: No.
The Evidence: Ballistics
Police believe it was an Erma Werke ET22, a rare .22 semi-automatic. A 2012 release also named the Intratec Scorpion as possible.
CCI brand .22 rounds with copper-clad lead bullets were used in all six killings.
A red powder on every casing tested as jeweler's rouge. The killer likely polished rounds so they chambered easily.
The same gun was used in Indianapolis, Wichita and Terre Haute. Ballistics later tied all six murders to it.

Shell casings are held as evidence. St. Charles police also own an identical ET22 bought online.
Touch DNA: Saved Items
The wedding veil
The killer wrapped it around the gun to muffle shots. Detectives called it the best chance for touch DNA.
McCown's pants
Michael McCown's wallet was missing. Police believe the killer reached into his pants, so they kept them.
Not definitive
First Terre Haute tests came back without definitive findings. By 2024 reports called the DNA "a dead end" so far.
What Does Not Exist
No fingerprints
No prints from the 1992 scenes are reported. In 2012 a Wichita lieutenant said there were no prints to work with.
No video
No usable store video from the 1992 scenes is reported. The only clear tape is from a 2001 Terre Haute case police treat separately.
No rape kit
No victim was sexually assaulted. No blood or semen from the killer has been reported, so there is no standard DNA sample.
Most solved cold cases start with a DNA profile from semen or blood. This case has none, so touch DNA and ballistics carry the weight.
Witnesses and Sketches
Sketches were made from witnesses. Age-progressed versions came out in Oct 2021, estimating he is now 52 to 70.
- White male, slim build, about 5'7", roughly 150 lb.
- Hair reported as dull red or sandy blond with a red tint.
- Wichita: a customer met him face to face. He is the only known person to do so.
- Raytown: a man in a gray sport coat, seen walking toward I-70.
- Sources differ on age and hair, so the sketch is a guide, not proof.
Behavioral Evidence
- Mostly small-framed women working alone.
- Shoe store, bridal and tuxedo shops, ceramics shop, boot store, craft store.
- Busy daytime areas near I-70 exits. Little money taken.
- Victims were led to back rooms and shot with the same .22.
Gaps of 3, 16, 6 and 4 days. About 700 miles lay between the first two scenes.
Fact vs Theory vs Speculation
Supported by reliable evidence.
- One gun, an Erma Werke ET22 type .22, was matched to all six murders.
- Red jeweler's rouge was found on the casings.
An explanation not yet proven.
- The killer wanted the thrill of killing, per the FBI profile.
- He lived near Indianapolis and drove out and back.
Little or no reliable evidence.
- Neal Falls was the killer. No evidence links him.
- The 2026 "Joe" claim, which is podcast hearsay and unconfirmed.
Traveler and Texas Link
A traveler or trucker
What: He worked or drove along I-70 and hit shops near exits.
Supporters: FBI profiler Larry Ankrom ("jobs on the road"); investigators.
For: One gun linked cities hundreds of miles apart within days.
Against: The FBI profile placed him near Indianapolis. No getaway vehicle was seen. "Trucker" is speculation.
4/5. The distances and exits fit a driver.
Texas 1993-94 killings
What: The same man killed in Fort Worth and Arlington and shot a survivor in Houston.
Supporters: Some police; the split is about 50-50.
For: Small stores near interstates, head shots, a .22, little money taken.
Against: Ballistics did not match. A gap of about 500 days.
2/5. The pattern fits, but a different gun is hard physical evidence.
Motive and Where He Went
Thrill vs robbery vs women
What: Why he killed. Supporters: St. Charles detectives and the FBI.
Thrill: "The act of the killing, not the robbery." Strongest.
Robbery: Little cash taken, a purse left. Weak.
Targeting women: Most victims were women, but hatred is unproven. Police think he may have mistaken McCown, who had long hair, for a woman.
4/5 for thrill. Robbery 1/5, women-targeting 3/5.
Dead or jailed
What: The killings stopped because he died or went to prison.
Supporters: Some investigators; Ankrom thinks he is alive.
For: It would explain the sudden silence after 29 days.
Against: A 2001 Terre Haute killing has similarities, so he may not have stopped. Nothing proves it either way.
3/5. It can't be tested, but a jailed man's DNA could be checked.
Named-Suspect Theories
I-65 killer
Supporters: St. Charles Det. Raymond Floyd (2022, "preliminary"). For: time frame, sketch resemblance. Against: he robbed and assaulted women, was about 47 in 1992, and died in 2013.
1/5. Crime type differs.
Fugitive in 1992
Supporters: Early tips. For: sketch resemblance, on the run that spring. Against: KMOV reports he was cleared in 2012.
1/5. Cleared by investigators.
2026 podcast
Supporters: One journalist, on a podcast. For: he says police questioned a man who said "Charge me or I'm out of here." Against: no police agency confirmed it. No name.
Not rated. Hearsay, not evidence.
Forensic Science in 1992
Ballistics
Examiners compared bullets and casings under a comparison microscope. This is how police learned one gun was used in three cities.
Early DNA
RFLP testing needed a large, clean sample like blood or semen. CODIS did not exist until 1998. Touch DNA could not be tested.
Fingerprints
Searches were manual or early AFIS. The national system (IAFIS) started in 1999. No 1992 prints are reported.
Sketches & sharing
Composites were hand drawn from memory. ViCAP existed (1985) but was voluntary, and NIBIN came in the late 1990s.

1992 vs 2026: DNA
| Tool | In 1992 | In 2026 | For this case |
|---|---|---|---|
| DNA analysis | RFLP and brand new PCR. Needed visible blood or semen. Labs were slow. | STR + PCR is routine. Sequencing works on tiny samples. | No semen or blood reported, so the case needs low-level methods. |
| Touch DNA | Not usable. Testing was limited to semen and saliva. | Skin-cell profiles can be built from handled objects. | Best hope: the Wichita veil and McCown's pants. |
| Genetic genealogy | Did not exist. | Over half a million SNPs searched against family trees. Works with distant cousins. | Most powerful tool, but it needs a killer DNA profile first. |
| CODIS | Not yet built. A 14-lab pilot began in 1990. | National database since 1998. 20 core loci required since 2017. | Helps only if an STR profile exists and he or a close relative is in it. |
1992 vs 2026: Prints & Data
| Tool | In 1992 | In 2026 | For this case |
|---|---|---|---|
| Fingerprint databases | Manual or early AFIS. | FBI NGI. Accuracy rose from 92% to over 99.6% in 2011. | No prints reported, so little to search. Cheap to double check. |
| Facial recognition | None. Hand-drawn composites only. | Software can match sketches to photo databases. | Gives a candidate list at best. The 2001 Terre Haute video is a clearer image. |
| Digital forensics, cell & location data | About 11 million US cell users. Rare. | Phones, apps and tower records are routine evidence. | Low use. No sign he had a phone, and old records are gone. |
| Surveillance cameras | No usable store video reported. | Cameras and plate readers are everywhere. | Today he would likely be filmed. That is part of why he escaped then. |
1992 vs 2026: Systems
| Tool | In 1992 | In 2026 | For this case |
|---|---|---|---|
| Artificial intelligence | None. | Text analytics can scan old case files for links. Still mostly in research. | Could search St. Charles's thousands of files. Lead generator only. |
| Databases: ViCAP & NIBIN | ViCAP was voluntary. NIBIN did not exist. | NIBIN ranks casing images across the country. ViCAP compares behavior patterns. | Strongest untested lead. Whether the casings are in NIBIN is not reported. |
| Geographic profiling | Rossmo's model was first published in 1993. | Software maps a likely base of operations. | Hard on a 700-mile corridor. Use it to rank exits and stores. |
| Toxicology Low relevance | Basic drug and alcohol tests. | Far more sensitive tests. | Cause of death was gunshots. Toxicology cannot name the shooter. |
1992 vs 2026: New Testing
| Method | What it does | Use here |
|---|---|---|
| WGS / SNP of degraded touch DNA | Sequences very small or damaged samples. One lab case used fewer than 20 cells. | Best fit for the veil and pants. A different test than the STR work that hit a dead end. |
| M-Vac wet vacuum | Pulls up about 12 times more DNA than swabbing on porous items (FBI study). | Possible on fabric, after gentler options. Can add mixtures. |
| Probabilistic genotyping | Software that reads mixed or weak DNA using all the data. | Sorts the killer from victims and handlers. |
| DNA phenotyping | Predicts eye and hair color from DNA. Face prediction is unreliable. | Could settle red vs sandy blond hair, if DNA exists. |
| 3D ballistic imaging | Scans casings in 3D for NIBIN. | Re-scan all casings and the reference ET22. |
Old Cases, New Science
Yogurt shop murders
A cold-case detective resubmitted a 1991 casing to NIBIN in June 2025. It had not been entered in years. In July it matched a 1998 Kentucky murder. A Y-STR DNA match then pointed to Robert Eugene Brashers, who died in 1999.
Harry Greenwell, I-65
The FBI's genealogy team helped Indiana State Police identify Greenwell as the I-65 killer of motel clerks (1987 to 1990). He died in 2013. Kinship testing confirmed it. Ballistics had linked two of the murders.
Golden State Killer
Crime-scene DNA matched a distant relative on GEDmatch. Investigators narrowed by age and location, then confirmed with a discarded item. Joseph DeAngelo, 72, was tied to 12 murders and 50+ rapes.
Reopened Today: Part 1
1. What evidence still exists?
Evidence from each scene was saved for 30 years. Named items: the Wichita veil, McCown's pants, casings with red jeweler's rouge, and a reference ET22 bought by St. Charles police.
2. Could it be tested again?
Yes, and some was. A Terre Haute item went to a Florida lab in 2022. Results: "no definitive findings," then "a dead end." Limit: testing uses up the sample.
3. Could newer DNA techniques be used?
Possibly. The 2022 work sounds like standard STR testing. Sequencing (SNP) methods are different. Whether they were tried is not reported.
4. Could genetic genealogy help?
Only if testing recovers the killer's DNA. No blood or semen was reported, so this is a real risk. If a profile appears, it is the strongest tool there is.
Reopened Today: Part 2
5. Modern databases?
Yes. Re-scan casings in NIBIN, as Austin did in 2025. Enter all cases in ViCAP, plus the 2001 and Texas cases as "possibly linked." Whether this was done is not reported.
6. Identify or eliminate suspects?
Eliminate: yes, with DNA. The 2001 Terre Haute man's DNA did not match. Identify: only through DNA, genealogy, a NIBIN hit traced to a gun owner, or a tip.
7. What else is needed?
At least one of these: a DNA profile of the killer, the ET22 or casings matched to the scenes, a tip from someone who knew about the gun, or a clear photo or video.
Technology Beyond 2026
Theory These are my reasoned predictions, not facts.
Less DNA needed
One vendor already claims usable genealogy profiles from very low coverage. If this keeps improving, samples that fail today may work in 5 to 10 years.
Bigger family-tree databases
More people testing means closer relatives. The Golden State match needed only a distant one. Laws may tighten, though.
Objective 3D matching
NIST is building 3D toolmark data to give ballistic matches a measured confidence. Worn or poorly imaged casings could be read better.
AI case linking, with limits
AI could link old files across five agencies. Experts warn about validation. Age-progression of faces is unproven. Phone data will not help a 1992 case.
Who Has Been Eliminated?
Donald Waterhouse
Why a suspect: His parents were shot in Tennessee a month before. A composite looked like him.
Connection: He was a fugitive that spring. Found Oct 1992 after an America's Most Wanted tip.
Result: Cleared in 2012, per KMOV. Never charged.
Texas killings
Why a suspect: Similar shops, .22 caliber, head shots, 1993-94.
Connection: Fort Worth, Arlington and Houston attacks near interstates.
Result: The gun did not match the I-70 ballistics. Police are still split.
Harry Greenwell
Why a suspect: The I-65 killer, tied by DNA to three motel killings (1987-90). Died 2013.
Connection: Time frame and sketch resemblance.
Result: "Preliminary" in 2022. Age and crime type differ. No later update.
Weak Leads and the Key Question
Herb Baumeister
A KMOV feature raised him because he traveled I-70 and partly resembled the sketch. He was taller, with no physical evidence. He is usually tied to the separate "I-70 Strangler" case of men, which is a different crime.
Neal Falls
Listed in the same feature. Police had no physical evidence linking him to the early cases. He died in 2015, and CBS never links him to I-70.
- Ballistics (days): One gun in Indianapolis and Wichita proved a serial killer.
- Texas mismatch: A different gun weakened that link.
- Sketches: Gave the public a face, and a way to rule people out.
- 2021 task force and 2022 DNA: New testing began, but results were not definitive.
29 Days in 1992

Robin Fuldauer, 26, is shot while working alone at a Payless ShoeSource on Pendleton Pike.

Patricia Magers, 32, and Patricia Smith, 23, are shot at a bridal shop after staying late for a customer.

Michael McCown, 40, the only male victim, is shot at Sylvia's Ceramics, just north of I-70.

Nancy Kitzmiller, 24, is found shot in the back room of Boot Village. Exact time is not confirmed.

Sarah Blessing, 37, is shot at The Store of Many Colors. This is the last attack in the series.
Linking the Cases

A St. Charles detective matches bullets with the Indianapolis case. Police later say all six killings link by ballistics.

The Wichita customer and a St. Charles witness help produce two composite sketches. Raytown has the most witnesses.

FBI profilers study the cases and a task force forms. It guesses a man in his late 20s or early 30s tied to Indiana.

Three shootings in Fort Worth, Arlington and Houston look similar. Ballistics show a different gun, so police are split.

Clerk Billy Brossman is shot in a store seven blocks from Sylvia's. Police see similarities. Not confirmed.
Quiet Years, New Push

St. Charles police release new details on the gun and ammunition. Wichita says DNA is "out of the question."

Donald Waterhouse, a person of interest because a sketch resembled him, is cleared, KMOV reports.

The original task force, once holding about 67,000 names, is dissolved. Detectives still work the case.

St. Charles PD releases age-enhanced sketches. They estimate the killer is now about 52 to 70.

About two dozen detectives, plus ATF and FBI, meet to compare notes and plan DNA re-testing. Det. Kim Rhodes becomes full-time lead.
Status in 2026

Terre Haute submits one piece of 1992 evidence for DNA testing. St. Charles opens an online tip portal.

Terre Haute evidence goes to a Florida lab. Police believe the suspect touched it. Results are not public.

The late I-65 killer, Harry Greenwell, is looked at as a possible suspect. Police call it preliminary.

The task force keeps taking tips. In Aug 2025 the $25,000 reward still stands. No suspect is named.

No arrests at 34 years. A reporter's July 2026 claim of a questioned man is unconfirmed by police.
The ABCs of the I-70 Killer

ATF agents joined the 2021 summit of detectives in St. Charles.

Matching bullets linked all six killings. Boot Village in St. Charles was one scene.

The shots were .22 long rifle rounds made by CCI. Composite sketches are also key.

No DNA match has been found. Touch DNA testing began in 2021 and 2022.

Police think this rare German pistol is the most probable gun. About 6,500 were made.

Profilers guessed a man in his late 20s or early 30s who lived or worked in Indiana.

Genealogy identified the I-65 killer Greenwell. Police called a link to I-70 preliminary.

Every shop sat in a strip mall along I-70 or I-35. The road is the common thread.
The ABCs, Continued

The first victim, Robin Fuldauer, was shot here on April 8, 1992.

Red rouge was found on the casings. KMOV says the killer likely polished rounds with it.

Nancy Kitzmiller, 24, loved maps and was weeks from a federal job check.

The Wichita bridal shop where Patricia Magers and Patricia Smith were killed. Some outlets print "La Bridal."

Michael McCown was the only male victim. Police think the killer mistook him for a woman.

ATF's casing database. No source says if these casings were ever entered.
All five local agencies still hold the case open. St. Charles PD leads.

The Indianapolis store was on Pendleton Pike. It no longer exists.
The ABCs, Continued
Who was he? Is there usable DNA? Are Texas and the 2001 case his? All still open.

Sarah Blessing died in Raytown, MO. St. Charles PD offers a $25,000 reward.

St. Charles PD leads the case and released the age-enhanced sketches in 2021.

Terre Haute lost McCown. The task force shares leads. Texas is only a possible link.
No suspect has been publicly named after more than three decades.

A wedding veil muffled the Wichita shots and is a touch DNA hope. ViCAP use is not confirmed.

A customer saw the armed killer, refused to go to the back, and left. He gave the first sketch details.

The shops were along I-70 and I-35 across three states, a short drive from the highway.
The ABCs, Last Two
From 1992 to 2026 is 34 years without an answer. The families have waited that whole time.
No one has been arrested or charged for the I-70 killings, and no suspect is publicly named.
Six people lost their lives in 29 days. Anyone with information can call the St. Charles PD tip line, 1-800-800-3510.

Case Summary: The Unsolved
1. What happened? Six people were shot in five stores along I-70 in 29 days, April 8 to May 7, 1992. The cases are linked by ballistics.
2. Victims. Robin Fuldauer, Patricia Magers, Patricia Smith, Michael McCown, Nancy Kitzmiller, Sarah Blessing.
3. Evidence collected. Casings and bullets, red rouge on casings, the Wichita veil, McCown's pants, witness sketches.
4. Forensic evidence. One .22 pistol tied to all six. Probably an Erma Werke ET22. Touch DNA tests have been "a dead end" so far. No prints reported.
5. Major suspects. No one has been named or charged. Donald Waterhouse, Harry Greenwell and an unnamed 2001 Missouri man were looked at.
6. Eliminated. Waterhouse (cleared in 2012, per KMOV). Randall Bishop (DNA reportedly did not match). Lonnie Wiseman and Robert Craig Cox were already in prison at the time (one source).
Theories & Roadblocks
7. Strongest theories. A traveler or worker on the road Theory. A thrill motive, not robbery Theory.
8. Supports them. One gun used 700 miles apart within days. Stores near interstates. Little cash taken. FBI profile.
9. Contradicts them. The FBI says an Indianapolis-area base, so not a pure drifter. No getaway vehicle seen. "Trucker" is unproven.
10. Why unsolved? No semen or blood. 1992 DNA could not read touch DNA. Random victims, few witnesses. Five departments with no joint task force until 2021.
11. Could technology help? Yes, in two places: NIBIN re-scans of the casings and sequencing of the veil and pants. Genealogy works only if his DNA is found.
12. More evidence needed? His DNA, the gun, a tip, or clear video.
My Conclusion
An unidentified traveling offender
He was never matched to any named person. Everyone publicly considered was cleared or weak: Waterhouse, Bishop and the 2001 man's DNA did not match, and Greenwell differs in age and crime type. The only hard link is the gun, and it ties six killings together but not to a person. The facts fit a man who drove the corridor and returned to a home base, likely near Indianapolis, per the FBI. This is my judgment, not a proven fact.
- Who is he?
- Why did the killings stop after 29 days?
- Where is the ET22?
- Were the casings ever entered in NIBIN?
- Was the 2001 Terre Haute case or Texas the same man?
- Has sequencing been tried?
If I Led This Case in 2026
What would I do next? My three most important steps:
Sequence the touch DNA, then run genealogy
Target the veil, McCown's pants and the casings. Use gentle collection first and test a small part. Why: STR testing was a dead end, and sequencing solved the I-65 case.
Re-scan every casing in 3D NIBIN
Include the Texas and 2001 evidence and test-fires from the reference ET22. An examiner confirms any lead. Why: Austin's 2025 break came from a casing that sat unsubmitted for years.
Feed national systems, clear suspects
Enter all cases in ViCAP, resubmit any prints to NGI, run a corridor geographic profile, and get reference DNA for Greenwell and the 2001 man. Why: cheap, and it checks any new profile fast.
