MADISON, Wis. — Defense attorneys for the man accused of kidnapping a Wisconsin teenager and killing her parents acknowledged Wednesday that they’re starting the case at a disadvantage after their client gave detectives a detailed confession and said they’re not sure he can get a fair trial in the state.

According to a criminal complaint, 21-year-old Jake Patterson outlined in detail for detectives how he gunned down 13-year-old Jayme Closs’ parents on Oct. 15 in their home near Barron and abducted the girl. Jayme escaped last week from the remote cabin where Patterson had been hiding her. Patterson was arrested minutes later, and he was charged Monday with two counts of homicide and kidnapping.

Charlie Glynn and Richard Jones, Patterson’s public defenders, told The Associated Press that they face an uphill struggle. Glynn acknowledged that the complaint contains “a very thorough confession.”

“Yes, it looks like you start out behind the eight ball a little bit,” Glynn said.

Jones said the defense team will evaluate Patterson’s statements to determine whether they were given voluntarily and if they’re true. He cautioned that prosecutors have amassed 30 banker’s boxes full of evidence, but that the defense likely won’t receive any of it, let alone review it, until after Patterson’s Feb. 6 preliminary hearing.

Terry Sullivan, a Chicago attorney who prosecuted the John Wayne Gacy killings, said he wouldn’t have included so many details in the Patterson complaint.

“I’m befuddled as to why they would release this amount of their evidence,” Sullivan said. “It doesn’t take a lot to hold a defendant, especially on a case like this. This guy certainly doesn’t deserve any sympathy but, under our laws and our constitution, he at least deserves a fair trial. How do you get one if all the jurors have read this?”

Jones said he doubts Patterson can get a fair trial in Barron County or maybe anywhere in Wisconsin, given the publicity surrounding the case.

“(Barron) is a small community,” Jones said. “So many different people have had not only an interest in the case, but an actual involvement in the case, being part of the search , those things, being part of fundraisers. They’ve had physical, tangible involvement in the case. The question becomes, ‘Can you lay that involvement, that emotion aside and render a verdict based on this case?’ In that county, I think that could be extremely difficult.”

Barron, which lies about 90 miles (145 kilometers) northwest of Minneapolis, is home to about 3,400 people. Investigators took more than 3,500 tips during the three-month search for Jayme. Some 2,000 people participated in a ground search for her on Oct. 23.

The defense attorneys said they had an extensive conversation with Patterson in jail, but they declined to reveal anything that was said. They described his demeanor as “appropriate” for a 21-year-old facing such serious charges but didn’t elaborate.

They said they understand everyone wants to know Patterson’s motivation, and that it will become clear later as the legal proceedings continue, Jones said.
