Andre Santiago was 29 when he was killed in East Harlem in the early hours of June 27, 2015. Police found him in front of a building at the Jefferson Houses on East 115th Street with a gunshot wound to the head and multiple stab wounds to his torso. He was taken to a hospital and pronounced dead shortly after arrival.

The attack’s combination of a gunshot and multiple stab wounds suggested a particularly violent, personal assault and raised the possibility of multiple assailants or a premeditated attack. Despite investigators examining several potential suspects, no arrests were made and the case remained unsolved as the investigation stayed open.

Did anyone in the neighborhood or who knew Andre see or hear anything that night that could help move this case forward?
