Suicide by cop?

St. Louis Today via Gateway Pundit:

A former Affton High School football standout forced his way into a South County home and was shot and killed by an off-duty officer inside after a Facebook dispute over Black Lives Matter apparently boiled over late Saturday afternoon.

Yeah, he broke into a cop's home.

Gebhard threw a 50-pound concrete planter through the window and entered the Lakeshire residence as the officer's wife, mother-in-law and two young children struggled to escape through a bedroom window, St. Louis County Police Chief Jon Belmar said. The off-duty officer shot and killed Gebhard.

The Castle Doctrine is clear on this matter.
