GLENSHAW, Pa. — Police in a Pittsburgh suburb shot and killed a teacher who they say pointed a gun at them outside his home.

Allegheny County Police say Shaler Township officers responded to a report about a man behaving erratically on Tuesday afternoon. His wife was outside and told officers the man had access to firearms.

Police say 49-year-old Donald Babbit came out of the home and ignored commands as he advanced while pointing the handgun at them. Three officers opened fire. Babbit was wounded and taken to a hospital, where he died.

Babbit was a teacher in the Penn Hills School District. The district said in a message he had “the distinct reputation among students, families and colleagues as being an exceptional teacher. He will be missed.”
