Woman Who Says She Dated Jayme Closs' Alleged Kidnapper Describes Him As 'New Level Of Creepy'

A woman who says she dated the man accused of kidnapping Wisconsin teen Jayme Closs claims he exhibited disturbing traits since he was a teenager.

Jake Thomas Patterson, 21, was charged Monday with murder and kidnapping in addition to armed robbery for allegedly abducting 13-year-old Closs after killing her parents, James and Denise Closs, back in October. He had no prior links to Closs and allegedly told police he decided to abduct her after spotting her getting on a school bus.

Closs escaped last week after spending nearly three months in captivity.

A woman — who has only been identified as Briana  — told Radar Online that she dated Patterson for four months in 2011 when they were both high school freshmen. She described her teen boyfriend as "a new level of creepy.”

She told the publication that she believes he may have killed a dog. She said the deceased canine was found in a wooded area.

“That’s when he told me he was ‘experimenting’ with animals. I was like, ‘What the f–-k?’” said Briana.

She said he was infatuated with roadkill.

“It was an insane obsession of his,” she said. “His cabin was full of animal heads, but I don’t think people understand that he found those animals on the side of the road and stuffed them himself.”

Briana also claimed Patterson had anger issues.

“He’d lose his temper easily,” she told Radar Online. “He was quiet, but when he got mad, he was a completely different person.”

Even more bizarrely, she claims that during a fight at the cabin, the same cabin he’s accused of holding Closs captive for months, that he put on a mask.

“I saw his true colors that night, he was so full of rage," she said. “He literally scared the hell out of me. I was at the cabin, and he came out with this weird-looking masquerade mask. It was scary as hell.”

On Monday, Barron County District Attorney Brian Wright described the great efforts he allegedly took to conceal himself in order to get away with the kidnapping, including purchasing a mask and stealing license plates and putting them on his car when he went to the Closs home. Wright said that Patterson shaved his head and face in an attempt to avoid leaving his DNA at the crime scene and that he disengaged the dome light of his car so that he would be less visible.

Briana told Radar Online that when she dumped Patterson, he didn't take the breakup well.

“He slashed my mom’s tires a few days after we broke up,” she claimed.
