SALT LAKE CITY -- A man was killed in downtown Salt Lake City Friday after a vehicle pulled up and an altercation escalated into a fatal shooting, and just before 10 p.m. police released photos of the suspect and the vehicle.

According to information from the Salt Lake City Police Department, officers responded to a homicide in the area of 563 West and 200 South.

Det. Dennis McGowan, Salt Lake City Police Department, told FOX 13 News that a vehicle pulled up to the area and an altercation began around 4:30 p.m.

A man was crossing the street, and when he reached the south side of 200 South a gold vehicle, which police said they believe is a Mazda, with two people inside pulled up. Some kind of altercation occurred, police said, and then the passenger in the vehicle got out and fired at least one shot, killing the pedestrian. The suspects then fled and are still at large. The vehicle is described as being a 4-door model and gold in color. See the photos in the gallery at the bottom of this story for images of the car and one suspect.

Police said it is not clear if the parties involved knew each other. Police had shut down 200 South in the area and had also set up containment near the Road Home Shelter, as officers said some of the people in that area may have witnessed the incident or may have information about what happened. Just before 9 p.m., FOX 13 News' Annie Cutler reported that police tape was being taken down.

"South Rio Grande in front of the shelter, there's also police barricades and they feel as though there's witnesses or involved parties over in front of the shelter as well that may be able to provide additional information," McGowan said.

Officials said they are reviewing surveillance footage from businesses near where the shooting occurred and are interviewing witnesses. FOX 13 News will have more information as it becomes available.
