Witnesses and Suspects

The “Killer” Profile

Authorities developed a general profile of the suspect based on witness accounts and forensic evidence. They believed the individual was familiar with the area, including the bridge and surrounding trails—a local, or someone who had previously lived there. The suspect was thought to be calculated, calm, and willing to take risks. While sexual motivation was considered, it may not have been the only motive.

Bridge Guy

“Bridge Guy” emerged from a Snapchat video recorded on Libby German’s phone. The footage, though low-quality, showed a Caucasian male with thin, shaggy hair, wearing jeans and a blue coat, walking toward the girls. Audio captured him saying “down the hill.” Police described the suspect as a white male, aged 16–40, between 5’6”–5’10” in height, weighing 180–200 pounds. Bridge Guy remained the primary suspect for many years.

Richard Allen

At the time of the murders, Richard Allen was a 44-year-old resident of Delphi, Indiana, married with a daughter, and employed as a pharmacy technician at CVS. Locals described him as down-to-earth and friendly, though quiet.

He became a person of interest due to his presence on the trails the day of the murders. Allen voluntarily spoke with police, providing a detailed account of his movements, including his driving route and parking locations. While he had no prior criminal record, he did have an alias, Craig Ross Rentfrow.

Ron Logan

Ron Logan, the owner of the land where the girls were found, had a history of violence, alcoholism, and deception. He was caught in discrepancies when speaking with police about his whereabouts that day. Although his phone pinged in the area, he was never investigated further. Locals considered him capable of serious wrongdoing.
