A 5-year-old Lakeland boy was killed Thursday afternoon when his bike was struck by a pickup truck, according to the Polk County Sheriff’s Office.

Deputies say Austin Crawford and his 8-year-old sister were riding their bikes in a neighbor’s driveway when the boy turned and drove onto Saddlewood Boulevard. He was struck by the passenger side of the 1998 Chevrolet truck, driven by Carol McCallister, 46, of Lakeland.

The sheriff’s office received a call at 4:44 p.m., and Austin was transported to Lakeland Regional Hospital, where was pronounced dead.

Deputies said the incident appears to be an accident. The case remains under investigation.
