Like Joni Mitchell in her song “Big Yellow Taxi,” Tara Pakanich was woken late one night when the screen door slammed. She got up to investigate.

Downstairs she went to the basement where her son, Shad Thyrion, shared his bedroom with his girlfriend, Taylor Schabusiness. But when Tara investigated, she couldn’t see anyone. The light was on, but there was no one in.

What she could see, however, was blood. An awful lot of blood. So Tara woke up her boyfriend, Steve Hendricks, to see if he could help solve the mystery. And between them, they discovered the most horrific sights they would ever see.

They couldn’t believe their eyes, and when they called 911, the dispatchers couldn’t believe their ears.

After a hysterical Tara had handed the phone over to Steve, he told them they’d found body parts everywhere, including a severed head and a penis in a bucket.

Tara’s home in Stony Brook Lane, in Green Bay, Wisconsin, was about to become known as the House of Horrors.
