A video that apparently shows a 15-year-old after he was shot by a police officer in Connecticut was obtained by state police, authorities confirmed Sunday.

Police said they have seen the video posted Friday on Twitter and Instagram by Giovanni Rivera, who says he’s a cousin of Jayson Negron.

Police said Bridgeport Officer James Boulay shot Jayson after he struck the officer with a stolen car Tuesday. Police pronounced the teenager dead at the scene. Jayson’s passenger, Julian Fyffe, 21, of Bridgeport, was shot in the shoulder and is expected to recover.

No one in the car had a weapon.

The shaky one-minute video shows a handcuffed Jayson lying on the ground. The camera turns away from him and when it cuts back four seconds later, Jayson’s head changes direction. An officer is standing near him. Toward the end, an officer wearing gloves appears to reach down as if he is going to lift the teen. The sound of sirens can be heard and other officers can be seen in the background. Bystanders’ voices can be heard.

Rivera told the Hartford Courant that his family was told that Jayson was killed when he was shot, but thinks the video contradicts that. “If that crucial part of the story is a lie, everything else is up for question,” he said.
