Four people were killed in a crash involving two motorcycles near Modjeska Canyon Sunday afternoon, authorities said.
The crash was reported in the area of Santiago Canyon and Modjeska Canyon roads at about 4:35 p.m., according to California Highway Patrol incident logs.
Two motorcycles — each carrying a driver and passenger — collided and left four people dead, authorities said. The victims included two men and two women, CHP Officer Florentino Olivera said.
Olivera said a woman and a man were on each of the vehicles. They were all pronounced dead at the scene.
A witness said the crash happened when one of the motorcycles tried passing another vehicle and instead ended up crashing head-on into another motorcycle, authorities said.
"The motorcycle going northbound on Santiago Canyon (Road) — he was trying to overtake another vehicle that was going northbound," Olivera said. "In doing so, he went into oncoming traffic on the opposite side and collided with another motorcycle that was going southbound."
Olivera said investigators believe the motorcycle that caused the crash —a Harley Davidson carrying a 35-year-old and a 40-year-old — was likely speeding at the time.
The second motorcycle involved in the crash was a Honda carrying two 60-year-olds, Olivera said.
Santiago Canyon Road was closed in both directions at Hicks Road for a few hours while officers investigated, but has since reopened officials said.
