CANTON, Mass. (AP) — Massachusetts State Police are seeking the public's help as they investigate a fatal car crash involving an off-duty police officer.

The accident happened Feb. 10 in the late morning in Canton. Police say 74-year-old Ralph Hawkins was struck by a pickup truck as he stood in a neighbor's driveway. Hawkins was pronounced dead at the hospital.

The driver of the pickup, who police have not named, wasn't injured and stayed at the scene. The Norfolk district attorney's office confirmed the driver is a local police officer from a neighboring community.

State Police say no charges have been filed. They say they're looking for anyone who witnessed the crash or observed a white pickup truck being operated in or around Canton between 10 and 11:30 a.m. on Saturday.
