Marquis Adams, 31, was found slumped inside a car in an alley off the 11700 block of South LaSalle Street in Chicago’s West Pullman neighborhood just before dawn on September 20, 2015. Officers had been dispatched about 5:25 a.m. to a report of shots fired; Adams was located in the vehicle with multiple gunshot wounds and was taken to Roseland Community Hospital, where he was pronounced dead at 7:04 a.m. An autopsy listed the cause of death as a gunshot wound to the torso. Authorities gave his residence as the 4400 block of Ascott Court in Richton Park.

In the hours after the shooting the alley was described as quiet and yielded few public clues about a motive or the identity of a shooter. Police reports released immediately after the incident did not include a suspect description, and news coverage from the time did not mention any arrests. Detectives opened a homicide investigation and the case was added to the city’s 2015 homicide count.

If anyone remembers seeing activity in that alley or has information about who might have been near South LaSalle Street that morning, please share what is known with investigators.
