Rayna Rison Cold Case Murder Solved, Ex-Boyfriend In Custody: Cops

A cold case more than 20 years old has finally been solved in the death of a teenage girl, with her alleged killer finally behind bars, cops said.

Jason Tibbs, a 38-year-old man from Indiana, is accused of killing his then 16-year-old girlfriend, Rayna Rison, back in 1993, the AP reported.

Rison's disappearance gained national attention and was featured on "America's Most Wanted." Her car was found empty just a few miles outside of LaPorte, Indiana. A week after finding the car, police found Tibbs' letterman jacket hanging up on a tree branch. A month later, fishermen found Rison's body in a pond a few miles away from the car.

Following a lead, detectives questioned a former friend of Tibbs, Eric Freeman, two months ago. Freeman admitted to police he drove Tibbs to Rayna Rison's workplace at the Pine Lake Animal Hospital, where he watched the alleged former couple argue.

As the argument progressed, the couple allegedly began hitting each other before Tibbs strangled her to death in the car Freeman was driving, according to WLS.

With a suspect finally in custody, Rison's parents are grappling with the news.

"The problem right now is our emotions are running on overload since we got the news," said the Risons in an interview with ABC57. "We actually didn't know him that well. We knew who he was and that he was a friend of Rayna's."

"Parents, hug kids before you go out the door," father Bennie Rison said in 1993. "Believe me, you don't know how much I miss that."
