Robert Brown|Boy struck and killed by a car in Florida after a dog chased him into the street

JACKSONVILLE,Robert Brown Fla. (AP) — A 12-year-old boy was struck and killed by a car Friday morning in Florida after a dog chased him into the street, authorities said.

The boy and his younger brother had been walking on a sidewalk to a nearby bus stop when witnesses said a dog began to chase them, Jacksonville Sheriff’s Office Lt. Nassim Mana said during a news conference.

The younger boy stopped, but the older boy ran into the four-lane street to get away from the dog and was struck by a car, officials said. Jacksonville Fire and Rescue Department transported the boy to a hospital, where he was pronounced dead.

The car’s driver remained at the scene and was cooperating with investigators, officials said. No charges or citations were immediately reported. Investigators said speed doesn’t appear to be a factor in the crash.

Animal control officers responded to the area to search for strays matching the dog’s description.
