Jasmarr Anderson was 20 when he was shot dead late on July 20, 2013, near the Benjamin Banneker Apartments at 2101 West Seventh Street in Chester, Pennsylvania. Police were called at about 11:45 p.m.; officers found Anderson on the east side of the building with a gunshot wound to the head, no pulse, and he was pronounced dead at the scene. The medical examiner ruled the manner of death a homicide, finding a single close-range gunshot to the back-left portion of his head with a trajectory consistent with a shooter positioned behind him.

Surveillance video from the apartment complex showed Anderson walking with two men later identified as Alexander Garnett and David Colon. The footage appears to show Garnett dropping behind Anderson, positioning himself directly behind him, and moments later Anderson falling to the ground while the other two ran away.

At trial the prosecution presented the surveillance video, medical evidence, testimony from Anderson’s brother Shaquan Cooper, and recorded jail calls in which Garnett allegedly asked others to discourage or silence witnesses. The jury convicted Alexander Garnett of first-degree murder and possession of a firearm by a person prohibited; he received life without parole plus a consecutive five-to-ten-year sentence. Was anyone in Chester that night able to add details about what happened near West Seventh and Jeffrey Streets?
