On August 27, 2013, 19 year old Bryce Laspisa broke up with his girlfriend Kim by sending her a text message stating she’d be better off without him.

She recalled his behavior as being strange and unwell that night. He had also given away his personal belongings to friends, including diamond earrings he had gotten from his mother and his gaming console.

On August 28, 2013, shortly before 11:30 p.m, Bryce left Kim’s apartment in the city of Chico, California and was assumed to be driving back home to college.

Around midnight on August 29, 2013, his parents were notified by their credit card company that a card in their name had been used for roadside service in Buttonwillow, California, located off Interstate 5.

Bryce was thus believed to be driving back to visit his family home in Laguna Niguel, California, which was three and a half hours from Buttonwillow.

Growing concerned over her son’s well being after he never made it to their home, Bryce’s mother called the Orange County Sheriff’s Department at around 6:00 p.m. They found him eight miles away from the location where he had been serviced for the gas in Buttonwillow, Kern County.

Bryce passed a sobriety test, and reluctantly called his mother, reassuring her he was coming back soon.

On August 30, 2013, his mother received a call from Bryce shortly before 2:08 a.m. He told his mother that he was too tired to drive, and that he was going to pull over for the night. This was the last time Bryce was heard from.

Three hours later, at approximately 5:30 am, his 2003 beige Toyota Highlander SUV was found abandoned at the bottom of a 15-foot ravine off Lake Hughes Road near Castaic Lake. A caller reported the vehicle to the California Highway Patrol, who then notified Bryce’s parents at their home in Laguna Niguel.

The vehicle was overturned on the side of Main Ramp Road, about 100 feet from Lake Hughes Road, with the rear windshield broken out and some blood found inside.

Bryce’s personal belongings, including his ID, cell phone, wallet and laptop computer were left behind in the car, but he was nowhere to be found.

The circumstances of Bryce Laspisa’s disappearance remain unclear, and his case is currently classified as missing. His case remains unsolved over eight years later.
