ORLANDO, Fla. -

Family and friends of a 21-year-old Jacksonville man shot and killed at a BP gas station Monday night say they're devastated by what happened.

Nedzad Botonjic was shot and killed about 6:30 p.m. at the gas station on Atlantic Boulevard near Monument Road in Regency, Local 6 sister station WJXT-TV reported.

Police released a picture from surveillance video obtained by the BP gas station of the man they believe to be a suspect in the shooting.

Detectives said they have received information that the man may be from the Orlando area, but have not released the suspect's name.

Witnesses told police two men sped off down Live Oak Drive after the shooting in a small red four-door vehicle (pictured in surveillance photo). The vehicle has a temporary tag.

“It appears it happened very quickly, according to some of the witnesses," Sgt. Craig Waldrup said. "There was a small altercation, and then they heard gunshots. It happened very quick.”

The altercation took place outside the store in the parking lot, and several people witnessed the shooting, Waldrup said.

He said some witnesses attempted to follow the vehicle that left the scene but were unable to.

Botonjic arrived at the gas station alone in a vehicle, Waldrup said. It is unclear how many times he was shot or if he knew the suspects.

Anyone who has any information about the location of the vehicle or the identity of the suspects is asked to contact the Jacksonville Sheriff's Office at 904-630-0500 or email JSOCrimeTips@jaxsheriff.org. To remain anonymous and receive a possible reward up to $3,000, contact Crime Stoppers at 866-845-TIPS.

Botonjic was born in Germany, grew up in Jacksonville and attended Englewood High School.

A funeral for Botonjic will be held at 1 p.m. Wednesday at the Islamic Center of Northeast Florida on St. Johns Bluff Road.
