Sally Sines, 47, of McKees Rocks, was found dead in her home on February 18, 2021, alongside her boyfriend, 55-year-old Christopher Gumm. Stowe Township police located both bodies during a welfare check and determined both had been shot; both were in an advanced state of decomposition when found. Detectives say Timothy Gumm, 60, brother of Christopher, committed the killings.

He was arrested and charged with two counts of criminal homicide and one count of person not to possess a firearm. Police reports say Timothy initially denied being at the house but later admitted to arguing with his brother and shooting both victims; officers allege Timothy was upset that Christopher and Sally were living in their parents’ house. Sally is remembered by family as a kind-spirited mother and daughter whose death has deeply affected loved ones.

Does anyone have information about Sally’s last weeks or who might help explain what led to this tragedy?
