June 30, 2013— -- Police were searching today for a gunman following an alleged road rage shooting in Tampa, Fla., that left one man dead.
The victim, whom authorities have identified as 47-year-old Fred William Turner Jr. of Orlando, Fla., was driving on a Florida highway when he called 911 to tell dispatchers he was being followed by a man with a gun after leaving a nearby store, ABC Tampa affiliate WFTS-TV reported.
"We know that at one point in time, this person did pull up beside him and showed him a hand gun," Hillsborough County Sheriff David Gee told "Good Morning America."
"During the time he was on the call with the Highway Patrol, they actually heard the shooting. There were a series of shots," he said.
Authorities responded to the scene to find Turner shot and killed in his car on the side of the roadway.
It is unclear what provoked the alleged dispute between Turner and the suspect, who fled after the shooting.
Law enforcement officials are looking for a gray, Ford Taurus with tinted windows, WFTS-TV reported.
From a man pulling a gun in a road rage fight in North Carolina to a bruising brawl in the middle of a California highway recently, aggressive drivers are a growing threat on the roads.
According to the Department of Transportation, road rage incidents are up 170 percent since 2007, and there have been more than 1,000 deaths attributed to road rage since 2007.
