A 49-year-old man from Valley Center was identified as the motorcyclist killed in a crash on the State Route 52 in Kearny Mesa.
Robert Mitchell Briscoe died after he was ejected from his motorcycle, along with a female passenger.
The crash occurred just after 8 p.m. Monday on westbound State Route 52 near Convoy Street, according to the California Highway Patrol (CHP).
Briscoe was driving a 2009 Harley Davidson motorcycle when he rear-ended a Honda Civic.
CHP officials said he had been driving at more than 70 miles per hour. The impact of the collision sent two people on the motorcycle flying off.
The driver of the Honda, who didn't identify himself, told NBC 7 that he heard two loud booms before he was pushed onto the shoulder of the freeway.
An EMT who was driving by the collision stopped and attempted CPR on Briscoe but he was pronounced dead at the scene.
