SYRACUSE, N.Y. -- A newly released surveillance video shows at least four men with handguns seconds after a Syracuse police officer ran into a fleeing crowd Sunday on the city's Near West Side.

The video released today by Syracuse police shows two men with what appear to be handguns creeping up close behind the officer, Kelsey Francemone, as she runs toward what police say were shots fired during a Father's Day party.

Syracuse police are asking the public to watch the video and report the identities of any witnesses to investigators.

Seven seconds into the video, people start running from the right side of the screen to the left.

Francemone appears about 23 seconds into the video, beside a car near the James Geddes apartments. The video was taken by a street surveillance camera. Police Chief Frank Fowler would not say where the camera is located.

Francemone had responded shortly after 11 p.m. Sunday to a report of a person down and was apparently finished with that call when the police department's section of the video starts.

The video, which has no sound, then shows at least 100 people running from the right to the left of the screen. They were apparently fleeing from gunshots in an area off-screen.

About 27 seconds into the video, Francemone, wearing her blue police uniform, runs in the opposite direction, apparently toward shooters who are not shown in the video.

Two men appear to pull out handguns and follow closely behind Francemone for a few seconds, then turn around and walk away without incident. Francemone doesn't appear to be aware that the two men were behind her with guns.

About 40 seconds into the video, a man in a white shirt and white shorts appears at the bottom right of the video. He points a handgun in the direction Francemone had run.



At the same time, at the top of the screen, a man wearing a dark shirt and dark shorts appears to fire at least two shots from a handgun toward the right of the screen as he's walking the other way. Two muzzle flashes can be seen coming from his gun.

The video does not show Francemone firing her gun or the victim getting hit. That took place out of view.

Fowler would not comment on the video or on the investigation into the incident.

Francemone arrived at the scene alone when she ran into the crowded party to break up a gun fight, according to Jeff Piedmonte, president of the union that represents Syracuse police officers.

When she got to the scene of the gun battle, the shooters refused to put down their guns and she fired hers, Piedmonte said.

The incident ended with one man, Gary Porter, fatally shot and his girlfriend shot in the leg.

Three witnesses told Syracuse.com that the officer shot Porter, who they said was unarmed.

Police have not said whether Francemone shot Porter or his girlfriend. They have confirmed the officer fired at least one shot.

Police said they found casings from four guns at the scene.

Police don't have surveillance video of the scene where Porter was shot, Piedmonte said.

After Porter was shot, Francemone went over to him when a crowd of people descended on her, Piedmonte said. They punched her, kicked her, spat on her and threw bottles at her, he said. They piled on top of her, took her flashlight and tried to take her gun, badge and pepper spray, he said.
