A Fremont man was arrested after a multiple-vehicle crash that killed a motorcyclist on southbound Interstate 680 in San Ramon on Monday morning, according to the California Highway Patrol.
The 23-year-old man was taken into custody on suspicion of felony DUI and vehicular manslaughter while intoxicated, CHP Officer Derek Reed said.
Authorities declined to release the arrested man's name, citing the pending investigation.
The motorcyclist killed in the crash was identified Tuesday as 39-year-old William Jimenez-Espinoza. The Martinez man died in the chain-reaction collision reported at 4:38 a.m. Monday on southbound I-680 south of Bollinger Canyon Road, CHP officials said.
The Fremont man's Honda struck the back of a big-rig and spun out. The disabled Honda was then struck by Jimenez-Espinoza, who was ejected from his motorcycle. A second big-rig then struck Jimenez-Espinoza, who was pronounced dead at the scene, CHP officials said.
Reed said that neither of the truck drivers was injured.
The Honda driver was arrested at the scene and was booked into jail on $150,000 bail.
