On the evening of January 29, 2018, police were called to a rowhouse on the 1200 block of Greeby Street in the Oxford Circle section of Northeast Philadelphia. A 39-year-old man who lived there let officers into the home. Inside, 66-year-old Adeline Hill, who used a wheelchair, was found on the ground floor with a fatal gunshot wound to the head. Her 42-year-old daughter, Renee Cosom, was found on the second floor, dead of a gunshot wound to the face.

There was no sign of forced entry, which led investigators to conclude the killer was likely known to the victims. The daughter’s boyfriend, Michael Drennon, a resident of the house, was taken into custody for questioning; a weapon was recovered at the scene. Drennon was later charged with both murders and convicted on two counts of first-degree murder, receiving life without parole for the execution-style killings of Cosom and Hill.

Does anyone have information about the household or the victims’ movements in the days before January 29, 2018?
