Huntington Beach police are searching for a motorist they believe intentionally struck bicyclists in three separate incidents that occurred in less than an hour Sunday evening. Two riders were injured, and the third was killed.

All three incidents happened in Huntington Beach in an area bordered by Heil Avenue, Edwards Street, Warner Avenue and Springdale Street.

Police are searching for the unidentified driver of a black Toyota four-door sedan that sustained front passenger-side bumper damage, according to witness reports.

“We believe that the incidents are related because the three locations are close in proximity and also based on the victims’ and witnesses’ statements,” said Jessica Cuchilla, a Huntington Beach police spokesperson. “They all described a similar vehicle.”
