A man died Friday night when he was thrown from his motorcycle in a crash on the city’s west side.

Police say Randall Staggs, 52, was riding west on Colorado Avenue when his Honda hit a Toyota Camry, which was turning left onto 31st Street.

Staggs, who authorities say was not wearing a helmet, was thrown from his motorcycle and suffered severe injuries. He died a short time after the crash at a hospital.

The driver of the Camry, Ryan Hieronyumus, 20, was uninjured.

Police said they’re investigating to figure out what caused the crash and who was at fault. Alcohol is not thought to be a factor.
