Police say two speeding motorcyclists died April 17 in unrelated accidents.
One crash happened in Fullerton when Francisco Sandoval, 32, of La Mirada crashed his 2006 Suzuki motorcycle into a wall at the intersection of Euclid Street and Rosecrans Avenue.
Responding officers found Sandoval with life-threating injuries, and he was later pronounced dead at the scene.
Earlier that day, a 22-year-old man died in Long Beach after losing control of his motorcycle while travelling northbound on Atlantic Avenue from South Street.
He collided with a building and later died in hospital.
Police believe speed was a factor in both cases.
