1990-1999

Corinna Marr, 25, was killed in her Collinswood, South Australia home on July 4, 1997, by an unidentified intruder. Investigators named a suspect in 2004 who later filed defamation lawsuits against two media organizations and the state of South Australia. He denied killing her, and his legal team accused the victim’s husband, Robert Marr, of her murder. Police never charged either man, and the case remains officially unsolved.

On Oct. 31, 1995, Shana Marie Jaros, 18, hosted a small party with three guests at her studio apartment in the small town of Nokomis, Illinois. By 7 a.m. the next day, the young nursing assistant was dead, brutally stabbed more than 50 times in the chest and neck.

Robert Thomas Pillsen-Rahier, 15, vanished from the Cheyenne Mesa Adolescent Treatment Facility in Colorado Springs on July 6, 1990. During his final phone call with his mother, he said he had something to tell her but did not want to speak over the phone; the facility monitored phone calls. His mother planned to visit her son to discuss the matter, but he disappeared before she could. She has reason to believe someone at the facility had sexually abused him.

Erin Marie Gilbert, 24, disappeared on July 1, 1995, after attending the Girdwood Forest Fair in Girdwood, Alaska, with a man she had recently met, David Combs. Following the fair, Combs claimed his car would not start, and he walked for two hours to find a friend’s home, leaving Erin in the car. Unable to locate the friend’s house, he arrived back at his vehicle, but Erin was gone, and the car started on the first attempt.
