Nowak, who was home alone at the time, remained completely silent and hidden, praying the creep would go away... which thankfully he finally does.
But things take an even more sinister turn when her husband, who isn't home with her, is alerted to the activity and uses the remote voice feature to demand the stranger identify himself.
The stranger stops in his tracks, and returns to the front door.
"Yeah! Can you hear me? What I'm looking for is for the girl that's in the house to come out here, because I'm going to rape her and kill her," he pleasantly declares, staring into the camera. "Can you have her open the door?"
"I'm going to rape and kill the girl that's behind this door when she lets me in. I want to rape her and kill her. I have a knife, and a gun."
"Yeah! And I'm just gonna knock on the door again," he announces — before walking away, for good this time.
"So this happened tonight... pretty scary!" Nowak wrote on Facebook. "I was home alone."
"You'll hear my husband jump on The Ring after a bit, he wasn't here... I was hiding where this guy couldn't see me and I never said a word.. that whole beginning he's just talking to himself."
"Police were called, the lady from 911 stayed on the line until cop got here. File was reported and I showed him the video. Searching for him.. enough to arrest if they find him. Hubby is home now. Lock your doors friends!!"
The man was later arrested in downtown Las Vegas after somebody recognized his photo from social media, KLAS reported. A nearby District Court Marshal took him into custody.
He was arrested on charges of stalking, coercion, and obstructing a police officer. It was not immediately clear if he was armed as claimed, although no weapons charges were pressed.
Police have yet to identify him, booking him as "John Doe."
"On a personal note, the power of community using social media is strong and this proves so! Thank you everyone!" Nowak wrote in an update to her Facebook post. "I'm just glad he's off the streets, and can't harm anyone else."
