TAMPA, Fla. (AP) - Authorities in Hillsborough County are investigating the cause of a fatal shooting, after a man was killed while on the phone with 911.
A Sheriff's Office report says 47-year-old Fred William Turner, Jr., of Orlando called 911 on Saturday to report that someone was following him while driving down Interstate 4. Turner told dispatchers that the car following him had earlier pulled up next to him and someone inside the car took out a gun.
Turner said he didn't know why the car was following him and while on the phone with 911, dispatchers reported hearing multiple gunshots.
Witnesses told authorities that Turner then pulled off the roadway as the suspect fled. Turner died at the scene.
Authorities don't know how many people were in the suspect's car.
