A fearless mom used a stick to fight off a deranged burglar who threatened to kill her family — just days after he was freed despite allegedly admitting to exposing himself to kids in a park.

Amanda Materi Brown was watching a late-night movie after putting her kids to bed last Thursday when she heard someone yelling from inside her home in Portland, Ore., she told KPTV.

“He was screaming really loudly,” recalled the terrified mom, whose husband was out of town for work at the time.

“I couldn’t really understand except, ‘I’ll kill you — I’ll kill everyone.'”

The intruder — later identified as  Timothy Reed — was holding a metal trash can lid like a shield, with an unknown object in his other hand, seemingly ready to attack, she said.

That’s when the protective mom said she decided to “meet crazy with crazy,” and grabbed a large stick she has always kept beside her bed.

“I yelled back and I just went for him,” she recalled — with doorbell footage capturing her screaming at him to “get the f–k outta here.”

“I just started swinging the stick at him and he started backing up from the house,” she said.

Police bodycam footage shows officers then closing in on the suspect, who was still holding the trash can lid — and who hit an arresting officer with a rock the size of a “softball,” according to the Portland Police Bureau, which said he’s now been cleared to return to duty.

The footage caught him yelling at the officers as they closed in, “I’ll kill you!”

Reed was arrested — and it emerged he’d been released just days earlier, despite being charged with exposing himself to kids in a park, and threatening to kill a cop who responded, according to the report.

He admitted knowing there were children around when he was naked — “but didn’t see a problem with it,” according to an arrest report, which said he “made rambling statements about ‘being told to do it by God.”

Reed was charged with burglary, escape, assault, assaulting a police officer and criminal mischief, cops said. He is being held at the Multnomah County Detention Center.

Brown says her youngest slept through ordeal, but her “oldest doesn’t feel safe in his house now.”

“I have that image burned into my retinas of somebody standing in my house,” she said.

“You know, bad things happen in life and we’re not going to let it make us afraid.”
