It's been five years since the death of Smithson Valley High School lacrosse coach Randy Perkins. Perkins was shot and killed at a party, but who did it and why are still mysteries. The family is now seeking closure, offering a $55,000 reward for information leading to a suspect.

Perkins' mother, Kandy Perkins, called her son beautiful. "[He had] big green eyes," she said.

Kandy told KENS 5 it's been a long road since her son's death.

The Perkins family is offering $50,000 for any information on Randall Perkins’ killer. Crime Stoppers is also offering an additional $5,000.

"Most people think this case is done. Even our closest friends in our community, they think this case is done. It’s so far from [done]. It’s not even close," said Kandy.

Perkins was killed five years ago at the Aspen Heights student apartment complex near the main University of Texas at San Antonio campus.

Perkins didn’t go to UTSA. He was a student at Sam Houston State University, and he often came back to Smithson Valley High School where he was a former athlete and alumnus, to coach lacrosse.

Now, his mom holds on to the hope that somebody knows something.

"There were a lot of kids at that party," said Kandy. "They should be graduated, some of them married. Maybe some of them even have their own children. I’m hoping that time has been on our side, and maybe some maturity has set in."

Anyone with information is urged to call Crime Stoppers or San Antonio police.
