Missing person Bryce Laspisa was last seen six years ago in Castaic, officials said Monday.

Los Angeles County Sheriff’s Department investigators and family members of Laspisa are still asking for the public’s help locating him. He was driving from Placer County to Orange County to see his parents in August 2013; however, he never made it to their house.

Laspisa’s parents called their then-19-year-old son as he was driving home from Northern California where he attended college. He told them he was driving on the 5 Freeway, but could not see any signs indicating exactly where he was, said Karen Laspisa, Bryce’s mother.

“He took a detour at 2:08 a.m. and got off the I-5 in a suburban area and was going to sleep in his car,” his mother said in a previous KHTS story. “I told him to call me when he got up the next morning.”

However, Karen Laspisa said that her son did not call back in the morning, and hasn’t made any contact with his parents since that last phone call.

Laspisa’s car was located between 4:20 a.m. and 5:15 a.m. by law enforcement officials, who had arrived at Castaic Lake for a training exercise. The vehicle was found 15 feet down a ravine on its passenger side.

“They found his cell phone, wallet with all of his credit cards, laptop and all of his clothing in the car,” Laspisa’s mother said.

Since that date, there have been alleged sightings, but no verified trace of Laspisa has been found.

Laspisa was last seen in Kern County Aug. 30, 2013, at approximately 2:08 a.m. and has not been seen or heard from since, according to Sheriff’s officials.

At the time of his disappearance, Laspisa was 19 years old and stood 5’11” tall, weighing 170 lbs with red hair and blue eyes. He was wearing white cargo shorts, a blue/white checker shirt and white/red Nike shoes, and has a tattoo on his left arm/shoulder area.

His loved ones are still very worried and asking for the public’s help locating him.

A page on Facebook called “Find Bryce Laspisa” is dedicated to sharing possible sightings and organizing events to find him.
