The late-night collision occurred near Kingsley Street and Tudor Avenue, where investigators also examined a heavily damaged vehicle about a mile away.
MONTCLAIR, CA — Police were searching Sunday for a driver after a vehicle reportedly struck a group of bicyclists late Saturday in Montclair, leaving an active investigation at an intersection south of Interstate 10.
The collision was reported just before 11 p.m. Saturday at Kingsley Street and Tudor Avenue, according to reporting from KABC-TV. Video from the scene showed several bicycles scattered in the roadway as police and emergency crews worked in the area. Authorities had not released a confirmed accounting of the number of people killed or injured as of Sunday afternoon.
Initial reports circulating Sunday described two people as having been killed and multiple cyclists as having been struck. However, that casualty count could not be independently confirmed in the available reporting. KABC reported that video appeared to show a covered body at the collision scene, but Montclair police had not publicly provided a full casualty total when the station published its report.
Investigators were also examining a vehicle about a mile from the crash scene. Video showed the car with severe damage to its front end. Authorities had not publicly said whether the vehicle had been confirmed as the one involved in the collision or explained how investigators located it.
Police described the incident as a hit-and-run investigation and were seeking the driver. No description of the driver had been released, and authorities had not announced an arrest. Officials also had not disclosed what may have led to the collision, the direction the vehicle or cyclists were traveling, or whether speed, alcohol or drugs were suspected factors.
The intersection has appeared in previous city traffic-safety planning. A Montclair Safe Routes to School report identified Kingsley Street and Tudor Avenue as a high-collision intersection based on earlier crash data. The historical designation does not establish a cause for Saturday night’s collision but provides context for traffic-safety concerns in the area.
California’s Transportation Injury Mapping System tracks fatal and injury collisions using statewide crash data reported by law enforcement agencies. The system includes bicyclist injuries and fatalities among the categories used to examine traffic-safety patterns, though records for a newly reported crash may not immediately appear in statewide databases.
Authorities had not released the names or ages of any victims as of Sunday afternoon. Additional information about the number and condition of injured cyclists also remained unavailable. Police were continuing to investigate the collision and the damaged vehicle while seeking the driver who left the scene.
