Alex Hartzell was 24 when he was found shot multiple times in the backyard of a home on East Chestnut Street in Coatesville on the morning of August 26, 2016. A white male from Pottstown and an Owen J. Roberts High School graduate, Hartzell was described as musically inclined and was experiencing homelessness at the time, sometimes staying in local shelters.

Investigators focused on a suspect known as Butter, identified in reports as Lenn T. Tucker Jr., 25, of addresses in Philadelphia and Coatesville. Surveillance footage reportedly shows Tucker meeting Hartzell on a street corner, following him into the backyard, firing at close range, then standing over Hartzell and firing additional shots before leaving. Witnesses said Tucker sold drugs in the area; one witness identified him in a photo array.

Tucker was arrested and charged with first-degree murder, possessing an instrument of a crime, and being a convicted felon in possession of a firearm. During an interview he admitted following Hartzell but claimed others were present, a statement contradicted by the video. Did anyone who knew Alex or who was in that neighborhood that morning see anything that could help the case?
