LAKE CHARLES, LA (KPLC) - What happened to David Briley remains a mystery to investigators. He was last seen August 20, 2007. According to detectives David left his trailer off Highway 397 and walked down to a nearby convenience store, where evidence shows he made a purchase there.
"That was the last time anyone has heard or seen of David Briley. We don't have any evidence to prove foul play was involved, but we don't have any evidence to prove it wasn't either," said Calcasieu Parish Sheriff Tony Mancuso.
Three years later David's older brother has accepted the reality that he's likely dead.
"I feel in my heart of hearts that he's not here anymore, because he probably couldn't survive on his own," said Bill Briley.
Bill says David was involved with drugs around the time of his disappearance and had just lost his job. He says even though they weren't close - the family still needs closure.
"He is my brother and I would like to know where he is or what happened to him," said Bill.
Bill believes the answers lie with the people David was living with. "We can only go by information we receive from witnesses or close friends. Everything we have done has turned up nothing," said Sheriff Mancuso.
David's picture and the details surrounding his disappearances are now featured in the Louisiana Crime Stoppers Cold Case card deck. The cards are circulating in every prison throughout Louisiana in hopes someone will see it and start talking.
"I think the people he was with know exactly what happened to him and until one of those people says something we are not going to find out," said Bill.
Until then the case remains classified as a missing persons case. Meanwhile anyone with information on David Briley's whereabouts is asked to call Crime Stoppers at 439-2222. Callers can remain anonymous.
