SHALER TOWNSHIP (KDKA) – One man was killed in an officer-involved shooting in Shaler.

It all started as a domestic dispute on Tuesday on the 800 block of Spencer Grove Lane in Shaler Township, Allegheny County.

The man’s wife said her husband was acting erratically and he had weapons in their home. So, she called 911.

Shaler Police, backed up by Allegheny County Sherrif, surrounded the home as the man barricaded himself inside.

He ignored calls from police to surrender and commands to put his weapon down.

Eventually, the man came outside, and police say he pointed the weapon at officers. He was then shot by police.

KDKA has confirmed that the man shot, Don Babbit, was a teacher at Penn Hills.
