Authorities say they have jailed a 21-year-old man on kidnapping and homicide charges in the October killing of a Wisconsin couple and abduction of their teen daughter, who was found alive.

Douglas County Sheriff Thomas Dalbec said at a news conference Friday that Jake Thomas Patterson was arrested Thursday after Jayme Closs was found near Gordon, where Patterson lives.

Barron County Sheriff Chris Fitzgerald says investigators believe Patterson killed Jayme's parents because he wanted to abduct her, and that Patterson "took many steps to hide his identity."

"We do believe Jayme was the only target. I can tell you that the subject planned his actions, and took many proactive steps to hide his identity from law enforcement and the general public."

On Thursday, Closs walked away from a cabin where she had been held. Dalbec says Patterson was arrested based on a description of his vehicle that Jayme was able to provide.

Jayme approached a woman out walking her dog in a neighborhood, who notified a neighbor who called 911.

Detectives pursued thousands of tips, watched dozens of surveillance videos and conducted numerous searches in the effort to find Jayme. Some tips led officials to recruit 2,000 volunteers for a massive ground search on Oct. 23, but it yielded no clues.

Barron County Sheriff Chris Fitzgerald said in November that he kept similar cases in the back of his mind as he worked to find Jayme, including the abduction of Elizabeth Smart, who was 14 when she was taken from her Salt Lake City home in 2002. She was rescued nine months later with the help of two witnesses who recognized her abductors from an "America's Most Wanted" episode.

"I have a gut feeling she's (Jayme's) still alive," Fitzgerald said at the time.

He was right.

During the 20 minutes Jayme was in their home, Kasinskas and her husband, Peter, tried to make her feel more comfortable, they said. They offered her water and food, but she declined both. Jayme was quiet, her emotions "pretty flat," Peter Kasinskas said.

Jayme told the couple she didn't know where she was or anything about Gordon. From what she told them, they believed she was there for most of her disappearance.

Gordon is about 40 miles (64.4 kilometers) south of Lake Superior and about 65 miles (104.6 kilometers) north of Barron, Jayme's hometown. Gordon is home to about 645 people in a heavily forested region where logging is the top industry.

The Douglas County Sheriff's Office confirmed on its website that Jayme was found in the town at 4:43 p.m. Thursday, and that a suspect was taken into custody 11 minutes later. The Associated Press couldn't confirm the Kasinskases' account; the sheriff's office's non-emergency line rang unanswered Thursday night, and Sheriff Thomas Dalbec didn't respond to an email.

Sue Allard, Jayme's aunt, told the Star Tribune that she could barely express her joy after learning the news Thursday night.

"Praise the Lord," Allard said between sobs. "It's the news we've been waiting on for three months. I can't wait to get my arms around her. I just can't wait."

Barron Mayor Ron Fladten said Thursday night he was overjoyed at learning Jayme was alive.

"There was a lot of discouragement because this took quite a while to play out," Fladten said. "A lot of people have been praying daily, as I have. It's just a great result we got tonight. It's unbelievable. It's like taking a big black cloud in the sky and getting rid of it and the sun comes out again."

He acknowledged that Jayme may not be the same person she was before she disappeared.

"I hope that she's in good shape," the mayor said. "She's no doubt been through just a terrible ordeal. I think everybody wishes her a good recovery and a happy life going into the future."

The notification that Jayme had been found came just four hours after Fitzgerald had taken to Twitter to debunk a report that she had been found alive near Walworth County. Douglas County, where Jayme was found, is hundreds of miles northwest of Walworth County.
