YULEE, Fla. -- Nassau County Deputy Eric Oliver was fatally struck by a vehicle on A1A in Yulee while in the line of duty.

Sheriff Bill Leeper paused with emotion as he explained how Deputy Eric Oliver, 32, a seven-year veteran of the force, was hit by a vehicle while he was in pursuit of a suspect. He was pronounced dead on scene, according to First Coast News.

According to Leeper, there were Border Patrol Agents at the Gate Gas Station on A1A near Chester Rd. who were interviewing 6 people in a pick-up truck. Deputies with Nassau County were at the gas station on an unrelated call and were asked to stay to assist.

One of the six people in the truck fled on foot and two deputies chased after him across A1A. One deputy made it to the median but Oliver was struck by a vehicle.

FHP is investigating, but Leeper explained the incident as a tragic accident. The suspect is still at large and is vaguely described as a Hispanic male, 5'6", 150 pounds, wearing a grey tank top, dark jeans and black sneakers.

Sheriff Leeper said that he spoke with Oliver's wife and said that Oliver, "died doing what he wanted to do. He dedicated his life to protecting the county." Leeper said Oliver would be sorely missed.

Oliver and his wife have a 6-year-old daughter.

All westbound lanes on East State Road 200 are currently closed at this time.

Nassau Emergency Management has stated that there is an active manhunt in the area. They advise that all residents avoid the area.
