Joshua Goonan, 21, has been identified by the San Joaquin County Sheriff's Department as the man who died in a single-vehicle accident on Highway 88 on Sunday morning.
Goonan, according to the California Highway Patrol, was driving at an unknown speed on the highway when his 1994 Toyota Tacoma veered off the road and struck a guardrail and a tree. The accident took place shortly after 2 a.m. Sunday on Highway 88 east of Clements Road, authorities said.
Goonan sustained fatal injuries as a result of the crash, and authorities are not sure if alcohol or drugs played a role in the crash, the CHP said.
Goonan graduated from Tokay High School in 2007.
