Homicide detectives said Sammons was operating a 2009 Harley-Davidson motorcycle southbound on Newbridge Road when he struck a 2008 Chevrolet Malibu, which was making a right turn from Oak to go south onto Newbridge at the time of the crash.

Both vehicles were impounded for safety checks and the investigation is continuing, police said.
