A mother fatally shot an intruder she discovered in one of her children’s bedrooms, according to police.

Officials said the 33-year-old woman had returned home with her kids — aged 5 and 10 — when she encountered the man and opened fire.

Police officers and medical personnel arriving at the home in Portland, Oregon, early Sunday found the 59-year-old man who had been shot dead.

The mom is cooperating with the investigation and was not arrested, authorities said.

The case will be presented to the Multnomah County District Attorney's Office for review after the police investigation is complete.
