A shotgun believed to have been used by Patterson to shoot open the door to the Closs' home has been recovered by officers. He was jailed on suspicion of kidnapping and homicide.
Patterson is unemployed, although worked for one day at the Jennie-O Turkey Store in Barron, where the Closs' worked for 27 years.
Police said they sent three teams to tell family members at various locations that she had been found, including one group that was attending a basketball game.
Federal Bureau of Investigation special agent Justin Tolomeo told reporters: "In cases like this we often need a big break - it was Jayme herself who gave us that break".
They described the 13-year-old as the suspect's "only target" and said Jayme was "taken against her will".
"I'm lost and I don't know where I am, and I need help", Jayme told Nutter. [But] he knew what he was doing.
The terrified teenager was found by dog walker and social worker Jeanne Nutter, who said the girl begged for help and revealed her name.
The Baron county sheriff holds up a photo of the suspect, Jake Thomas Patterson.
The news that Jayme was safe set off joy and relief in Barron, which has a population of 3300. She spoke with WTVF about how the news of someone else's daughter coming home feels while her daughter is still missing.
Jayme's aunt says the healing process will be long but they are dedicated to putting her first. We had too much love and support around us for us to give up, ' her aunt said.
Jayme's aunt, Jen Smith, said on Saturday on ABC's Good Morning America that when she heard that her niece had been found alive, "I just cried lots of happy tears".

That, he added, will not happen again. "We don't want anybody going through what we had to go through this past month". We start off with one and gradually when you get into the new year, you often see a different strain taking over.
Relying on what Mr Fitzgerald called "the will of a kid to survive", a dishevelled Closs escaped the house in the tiny town of Gordon where she had been held captive, about 100km north of her home in Barron. "She did not talk about why or how".
Knight said she went through a range of emotions when she got out: sadness, fear, shame, and wondering if she would ever trust anyone again.
According to Douglas County Sheriff Tom Dalbec, Gordon police pinpointed and arrested Mr Patterson 11 minutes later thanks to a description of his vehicle that Jayme provided.

"I know all of you are searching for the answer why any of this happened", Fitzgerald said. "I also have to concentrate on my own sister, and it hurts that we don't have closure".
Patterson was not at home when Jayme escaped, the sheriff added.
The suspect made "great efforts to minimize his forensic footprint at the crime scene", Fitzgerald said, such as shaving his head to avoid leaving behind hair evidence.
Property records show that the cabin belonged to Patterson's father at the time of the teen's disappearance.
The cabin is in Eau Claire Acres, a development about 10 miles outside the tiny town of Gordon, nestled in the dense evergreen forests of northwestern Wisconsin that are popular with vacationers in the summer and snowmobilers and ATV riders in the winter.
Authorities blocked off the street that leads to the cabin from which Closs escaped Thursday and law enforcement has been going in and out all day.
Detectives pursued thousands of tips, watched dozens of surveillance videos and conducted numerous searches in the effort to find Jayme.
