A Jackson County Sheriff's Department Detective said that a woman found dead in a Black River Falls area dog park in May was stabbed 54 times.
The testimony came Tuesday at hearing to determine whether there is enough evidence to hold John B. Cook for trial in the death of Jacinda Muir.
Her body was found at the Black River Falls Pet Park in the Town of Brockway on May 17.
Cook was arrested later that same day. He faces one count of First Degree Intentional Homicide in Muir's death.
New details came out in court today related to the person who found the body of Muir on Sunday morning. Testimony from Jackson County Sheriff's Detective Kelly Bakken said that Cheemoua Thao was a friend of Cook's and had been partying together at a house in Black River Falls shortly before Cook and Muir left to go to the dog park.
The criminal complaint said that Cook took Muir to the park with the intention of beating her up, but it escalated and he stabbed her.
Autopsy details revealed in court Tuesday showed that Cook stabbed her 54 times in the head, neck, and torso.
Detective Bakken testified Cook said during his interrogation that he was using methamphetamine at the time of the stabbing. She said, "He explained he was using meth. He explained that after he killed her and went back to 209 Johnson Street that he used everything in sight. He described pills, shards, that kind of thing."
Emotions poured out from both the family of Jacinda Muir and John Cook when that testimony came out.
One of the most disturbing details in Bakken's testimony came when she recalled Cook talking about the stabbing, saying, "She wouldn't down. I had to keep stabbing her. She just wouldn't go down."
Following the testimony, Jackson County Judge Anna Becker ruled that there was enough evidence against Cook to go to trial. No date was set at Tuesday's hearing.
Cook remains in the Jackson County Jail on a $1 million cash bond.
