JACKSONVILLE, Fla. -

A 64-year-old Jacksonville man died Sunday after being struck by a pickup truck in reverse at a South Metro mobile home park, according to the Jacksonville Sheriff's Office.

Clarence Johnson was taken to a hospital, where he died.

Police said a 60-year-old woman was backing a truck onto a concrete pad at the Pine Oaks Mobile Home Park in the 4200 block of Philips Highway about 3 p.m. Sunday. While backing, the woman sideswiped another vehicle that was parked next to the pad attached to a camper, police said.

Johnson and another pedestrian began to yell at the driver to stop, police said. They said the driver panicked and tried to put on the brake, and the driver's foot slipped off the brake and hit the gas pedal.

Johnson and the other pedestrian were struck by the truck. Johnson was pinned underneath.

The other pedestrian had minor injuries.

Police said the driver was helping Johnson move into the camper. They said the investigation is ongoing.
