On December 20, 2014, around 4:15 p.m., officers responding to a ShotSpotter activation and a 911 call found 21-year-old Sayvon Marcus Burt of Freeport fatally shot in an alley off Park Avenue in Roosevelt, New York. He had sustained multiple gunshot wounds and was pronounced dead at the scene by a Nassau County Police Ambulance Medical Technician.

The Nassau County Homicide Squad investigated. Over the following months three suspects were identified and arrested: 18-year-old Elliott Fortune of Roosevelt was taken into custody in May 2015 and charged with second-degree murder, first-degree attempted robbery, and second-degree criminal possession of a weapon; 19-year-old Joel Villalobos of Freeport was apprehended in Georgia in April 2015 and arraigned in June; and 19-year-old Corey F. Walker of Hempstead was arrested in January 2016 on similar charges and a separate grand larceny count. Court records state the defendants attempted to rob Burt with a handgun and that one of the co-defendants shot him. Walker’s attorney entered a not-guilty plea and he was held without bail.

Does anyone have information about Burt’s last movements that afternoon or saw activity near Park Avenue that day?
