A teenager, Malachi Heisler killed a masked intruder holding a gun to mum's head, only to learn it was his dad, John Heisler.
The man who is separated from the family broke into the house with two guns to speak to his estranged wife.
"I had about five to six seconds to make a decision," said the 18-year-old.
"By the time I did recognise him, the decision was made."
Police said Heisler, 46, forced his way into the home, smashing windows as he went, while decked out in full black tactical gear, including a ski mask and thigh holsters.
