PITTSBURGH (AP) — A Pittsburgh mom faces felony child endangerment charges after she allegedly left her two young children home alone so she could help a friend who was about to fight someone nearby. City police went to Mattie Sims’ home after a neighbor asked them to check on the children, ages 4 and 1. Authorities say they found deplorable conditions in Sims’ home, and she was drunk when she came home about 30 minutes later. The children appeared to be unharmed but were taken to a hospital for evaluation.
