On the morning of April 26, 2017, a shooting in the 4500 block of Rosewood Avenue in Pine Lawn, St. Louis County, left three men dead. Officers arriving around 10:13 a.m. found 29-year-old Andrew Green, a Black male, among the victims; the other two killed were 29-year-old Calvin Walker and 23-year-old Marquise Cooper. One victim was located inside a black SUV, another on the sidewalk, and the third in a yard.

The North County Police Cooperative asked the Major Case Squad of Greater St. Louis to take over the investigation and circulated descriptions of vehicles of interest, including a white, older-model Chevrolet Impala with a driver-side spotlight and a black Nissan Altima. Despite public pleas from Andrew Green’s mother, Lanna Green, and community vigils, no suspects have been taken into custody and the triple homicide remains unsolved.

If anyone has information about the shooting or the vehicles of interest, please come forward.
