Cold Case Files (A&E / PodcastOne)

Episode: "Man in the Shadows / The Hitchhiker"

Date: March 24, 2026
Host and Narration: Marisa Pinson

Overview

This gripping episode of Cold Case Files delves into two chilling cases: the search for the "Linden Area Rapist" who terrorized Columbus, Ohio for over a decade, and the decades-old unsolved murder of hitchhiker Jerry Sullivan in California. Through survivor accounts, detective narratives, and forensic breakthroughs, the episode highlights the perseverance of investigators, the pain and resilience of victims, and the power—and limitations—of forensic science in achieving justice, sometimes decades after the crimes.

Case One: The Man in the Shadows (The Linden Area Rapist)

The Attacks Begin (01:47-08:24)

• Survivor Story:
  Christina Ruth recounts a terrifying night in February 1992 when an intruder attacked, choked, and raped her:

  • "He reached out and slammed the door open... he was choking me and beating my head into the floor and he kept saying he was going to kill me." (02:05–02:37)
  • During her ordeal, Christina dissociates: "You pray, you step out of your body. It's just my body. It wasn't me." (02:49)

• Investigation Stalls:
  DNA evidence is collected, but leads dry up.
  Christina is aware of the limitations:

  • "With DNA, it’s just like a fingerprint. Unless you have a person to go with that, it doesn't help." (03:14)

• Serial Assaults:
  Over the following months, at least five more women are raped in the same area, showing a clear pattern and a "man in the shadows" targeting his victims (03:42–05:11).
  Detective John Weeks observes:

  • "He committed attacks all the way up and down this segment of neighborhood here." (03:53)
  • All attacks share an MO: tall, heavyset Black male, often armed, engaging victims in conversation (04:32).

• Period of Quiet:
  The attacks suddenly stop in late 1992, baffling police. Weeks suspects incarceration or relocation might explain the gap (05:11–05:30).

A Resurgent Predator (05:38-12:24)

• Attack Resumes (1995):
  Pregnant victim Yvonne Merle is assaulted, linking her case to previous ones (05:38–06:41).
  Investigator awareness grows:

  • "His positioning of the victim, his entry into the house, his language spoken to her." – Detective Kevin Bailey (06:41)

• Patterns and Frustration:
  Despite releasing sketches and raising patrols, there are no leads. The attacks total at least 15 by spring 1995 before another sudden stop (07:28–07:44).

• Forensic Link Established (08:04–09:49):
  Detective Dave McKee revisits the cases:

  • "We took them out of the boxes and laid them out in a room... it hit home on how many cases and how many people were really involved." (08:24)
  • DNA matches link attacks from both periods, strengthening the serial offender theory.
  • "Those are consistent with prison terms in Ohio." (09:11) – detective speculates on gaps between assaults.

• No DNA Hits:
  Despite uploading DNA to CODIS, no matches are found, highlighting limitations of the system at the time (09:41–09:49).

Breakthrough and Capture (10:01-25:26)

• Predator Returns (2002 & 2004):
  A new assault in 2002 fits the MO. DNA confirms the "Linden Rapist" has returned (10:05–10:30; 13:08).

• Task Force and Modern Forensics:
  Task force formed, dozens of suspects swabbed with no success. The rapist is evolving, spreading his attacks further afield and changing his appearance (11:11–12:41):

  • "His description... went from one extreme to the other, from 5'5'' to 6'3''." – Detective Dave McKee (11:34)

• Diana Cunningham’s Experience (13:08–16:06):
  Diana survives a harrowing attack and uses her wits:

  • "I kind of felt around on his head, face, arms... found the scar on his arm. That was another identifying characteristic." (14:18)
  • She converses with her attacker:
    • "If you can get them talking... it makes it harder for them to hurt you." (14:42)
  • The assailant forces her to scrub the crime scene, erasing forensic evidence.

• DNA Breakthrough (19:02–20:17):
  Forensic scientist Rena Clarkson receives a DNA hit in June 2004. The backlog of untested samples delayed the match:

  • "That sample sat in a backlog for three years." – Narrator (20:30)
  • The rapist is identified as Robert Patton.

• Systemic Failures & Arrest:
  "The system failed, not advising law enforcement agencies that... we're not running the test from the swabs." – Detective Kevin Bailey (21:00)

• Confession and Sentencing (21:25–25:26):
  Patton candidly confesses to nearly all the attacks:

  • "If I can get to the judge or whatever... my plea won't change. Guilty." (22:10)
  • Guides detectives to 69 locations; is ultimately convicted on 58 counts of robbery and 76 counts of rape and assault.
  • "At one point, he said, 50 years isn't enough." – Christian Domus, prosecutor (25:00)

• Victim Reflections:

  • "When I found out that they had the evidence to put him away in 2001... It’s very hard not to be bitter about something like that." – Diana Cunningham (25:26)
  • Urgency is placed on reducing forensic backlogs to prevent future crimes.

Case Two: The Hitchhiker (Jerry Sullivan Murder)

Murder in Mendocino (26:10-29:15)

• Case Reopened:
  Detective Kevin Bailey picks up the 1975 case of Jerry Sullivan, a hitchhiker found shot and left in a sleeping bag in the woods (26:10–27:19).

• Initial Investigation:
  Crime scene offers little evidence besides Sullivan's cast leg, sleeping bag, and a cigarette butt. The victim's family soon receives his wallet in the mail (27:19–29:03).
  Technician Grover Beathards lifts a fingerprint from the wallet, but it's unidentified.

• Community and Counterculture:
  Detectives trace Sullivan's movements via people who picked up hitchhikers—including Kathy Smith and Summerhill West "commune" members (29:29–32:32).

  • "We were a counterculture... to actually initiate some sort of contact [with police] was a big deal." – Heidi Bohan, Summerhill resident (32:22)
  • "Bob Holt" is introduced as a possible suspect.

Long Road to Justice (35:31-45:44)

• Cold Files, New Technology:
  In the 1990s and 2000s, detectives revisit the case as a "wall of shame"—now with APHIS and then DNA (35:31–36:03).

• Original Suspects:
  William Cordero’s fingerprint is found in the wallet, but he denies any connection and cannot be charged (36:14–37:51).

• DNA Breakthrough:
  Detective Bailey finds the original cigarette butt and has it tested in 2004 (38:15–41:15).
  DNA leads not to Cordero, but to Robert Vaughn—a convicted murderer with a history of attacking hitchhikers.

  • "I did get DNA off the cigarette butt and I do have a match... It came back to Robert Vaughn." – Detective Bailey (41:15)

• Connecting the Dots:
  Vaughn is also known as "Bob Holt," the name noted decades before; Heidi Bohan identifies him from a photo (42:04–42:41).

• Confession and Resolution:
  Bailey and Tim Kiley confront Vaughn in prison. He admits the murder (43:33–45:36):

  • "We had an argument... So when he was asleep after the argument... he's sleeping." (44:47)
  • Vaughn is sentenced to seven years-to-life under 1975 legal guidelines (45:06).
  • Cordero is exonerated, but the mystery remains how his print was found in the wallet.

• Investigator Reflection:

  • "That cigarette butt's what brought us here... I submit that, guess what hits on you." – Detective Bailey (45:36)
  • Vaughn responds with dark humor: "Isn't that something? My favorite show is Cold Case documentaries..." (45:49)
