Ernest Nevin Mills Jr., 28, was shot and killed on November 9, 2020, in the Brighton Heights neighborhood of Pittsburgh. Mills was walking with his girlfriend to get pizza around 3:30 p.m. on Brighton Road near Davis Avenue when he was attacked. Officers attempted lifesaving measures but pronounced Mills dead at the scene.

The suspect, 26-year-old Laron Smith, lived in the same multi-family house as Mills. Witnesses said Smith had been acting strangely that day, screaming profanities and pulling a ski mask over his face before following Mills and his girlfriend. Smith was arrested two days later during a SWAT operation. He later pleaded guilty but mentally ill to third-degree murder; court testimony described a diagnosis of schizophrenia and psychotic symptoms preceding the shooting, and investigators found no clear animosity between the men.

Did anyone in Brighton Heights see Smith or Mills that afternoon or notice concerning behavior in the days beforehand?
