Isis Williams was 24 when she was shot and killed on December 14, 2018, inside a home on Woodstock Street near Chelten Avenue in East Germantown, Philadelphia. In the minutes before the killing she called her mother, screaming that her boyfriend, Tyrese Lynch, was at the door with a gun and saying he was going to kill her. Their newborn daughter, five days old, was in a crib nearby as Williams tried to lock herself in the bathroom to get away.

Prosecutors say Lynch forced his way into the house, reached the bathroom, and shot Williams at close range — wounds to the head, neck, torso, and hand — while the infant was only feet away. Williams’ mother heard the chaos and the gunfire on the phone, then contacted police and provided Lynch’s information; he was arrested shortly afterward. The case was prosecuted as a domestic killing; Lynch later pleaded guilty to third-degree murder, endangering the welfare of a child, and a gun charge.

Did anyone in East Germantown know Isis or the family and have information that could shed more light on the period leading up to December 14, 2018?
