In the early morning of March 5, 2015, police responding around 3:30 a.m. found 19-year-old Garrick Marshman of North Braddock deceased in the back seat of a disabled Toyota Camry parked sideways on the 3200 block of Lebanon Church Road in West Mifflin. An autopsy determined Marshman, who was African American, died of multiple gunshot wounds to his trunk. Investigators recovered six 9mm shell casings inside the car.

Allegheny County homicide detectives identified 20-year-old Deandre Smith of Braddock as the shooter; Smith was arrested the evening of March 5, 2015, and charged with homicide and a weapons violation. Marshman had been scheduled for a formal arraignment on drug and weapons charges the week after he was killed.

In June 2016 Smith, then 21, pleaded guilty to third-degree murder and was sentenced to 20 to 40 years in prison. Does anyone have information about Marshman’s final hours or the events that led to the shooting?
