The Wisconsin man accused of abducting 13-year-old Jayme Closs and killing her parents apparently had one and only girlfriend, who reportedly revealed there were signs of trouble in high school.

RadarOnline reports that the a former girlfriend of alleged killer and kidnapper Jake Patterson told the outlet she broke up with him after brief relationship after he showed his dark side to her in 2011, which included collecting roadkill, stuffing their heads and storing them in his garage.

“It was an insane obsession of his,” the former girlfriend, who attended with Northwood High School in Minong with Patterson, 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.”

The anonymous woman also said Jake would become a different person once he got angry, recalling a time he wore a mask after they had gotten into an argument and “scared the hell” out of her.

“I saw his true colors that night, he was so full of rage. 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.”

The woman broke up with Patterson after the incident but said he slashed her mother’s tires a few days later. Eventually they stopped communicating completely and she had all but forgotten about Patterson until she heard he was Jayme’s suspected kidnapper who shot her parents dead before abducting the little girl on October 15.

Patterson was arrested on January 10 after Jayme managed to escape his secluded home in Gordon while he was away. Jayme spotted a woman walking her dog and ran to her for assistance. Patterson was arrested shortly after when he returned home.

“I don’t want any ties to the scumbag – especially as his first and last girlfriend,” she reportedly told DailyMail.

Meanwhile, authorities are trying to figure out what to do with the $50,000 reward fund collected to locate Jayme. The family who called 911 on her behalf, Peter and Kristin Kasinskas, said they wanted none of the money and hoped it would all go to Jayme, the true hero, who managed to escape a violent criminal, according to Today.
