Two motorcyclists from Oceanside crashed their bikes on Interstate 5 near the Orange County/San Diego County border Sunday morning, killing one of them, authorities said.
Officers were dispatched at around 9:20 a.m. Sunday to northbound I-5, just south of the U.S. Border Patrol Checkpoint at San Onofre, according to the California Highway Patrol.
A 20-year-old rider of a black Yamaha motorcycle was behind a 22-year-old rider of a Honda CBR600 motorcycle, and for reasons under investigation, the rider of the Yamaha rear-ended the Honda, which caused both riders to be thrown off their bikes, authorities said.
The victim on the Yamaha was pronounced dead at the scene, and the other rider was taken to a hospital with moderate injuries. Alcohol or drugs were not suspected to have contributed to the crash, according to the CHP.
