On the morning of September 19, 2015, 27-year-old Michael A. Welsh was shot and killed in McKeesport, Pennsylvania, after a domestic dispute involving his companion Heather Guerra and her estranged husband, James Husok. Guerra went to Husok’s home after an argument with Welsh; Welsh later called and texted her and went to the area. Husok went outside armed with a 9mm pistol and a claw hammer, encountered Welsh in an alley behind the 300 block of 28th Street, and fired when he said Welsh appeared to reach for something. Welsh was found with a gunshot wound and pronounced dead at the scene.

Husok was arrested and charged with homicide, tampering with evidence, and weapons offenses. Investigators recovered ammunition at his home that matched a casing from the scene and other firearms. At trial Husok claimed self-defense; in October 2016 a jury convicted him of third-degree murder, tampering with evidence, and possession of an instrument of a crime. In January 2017 he received a 20 to 40 year state prison sentence.

Did anyone in McKeesport witness Welsh’s movements or the encounter behind 28th Street that night?
