Authorities say they are still puzzled as to why the suspect allegedly went to Barron to kidnap Jayme from the family home, where her parents were found dead, killed with a shotgun.
Jake Patterson, 21, is accused of shooting and killing Jayme's parents before abducting the 13-year-old at her northwestern Wisconsin home on October 15.
Police identified the man suspected of kidnapping Jayme as 21-year-old Jake Thomas Patterson. He was jailed on suspicion of kidnapping and homicide.
Fitzgerald hasn't said whether Jayme was sexually assaulted but said Saturday that investigators believe Jake Patterson acted alone.
Jayme's cousin, Angela De Andriano, is managing the gofundme account Jayme is Home - Help Heal her Heart.
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". "She said she did not know him".

Mrs Kasinskas told the Press she had not seen him on their street or in town since high school, describing him as "a quiet kid". He faces an initial court hearing on Monday.
Sheriff 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 taken from her Salt Lake City home in 2002, when she was 14 years old.
"Jayme had a pretty good night sleep it was great to know she was next to me all night what a great feeling to have her home".
"We are still mourning the loss of longtime Jennie-O family members Jim and Denise, but our entire team is celebrating with the community, and the world, that Jayme has been found", Lykken said.
Another aunt, Sue Naiberg Allard, posted that Jayme got "the most awaited hug ever" when he returned home.
He added: 'She did not talk about why or how. "We don't really know a lot, all we know is just she's alive".More news: Jadon Sancho reveals Callum Hudson-Odoi talks over Bayern Munich move
"I've always been a glass half-full kind of guy", Sheriff Fitzgerald said at the time. We believe he acted alone.
Patterson had worked for less than two days at a turkey processing plant where Closs' parents worked, but the sheriff said he did not have any contact with them.
"We believe Jayme was the target, and he (Patterson) was getting rid of possible barriers to taking her", Fitzgerald told CNN's Jean Casarez on Saturday. Property records show that the cabin belonged to Patterson's father.
She escaped and ran to a vacation cabin where Jeanne Nutter was just returning from walking her dog at around 4:30 pm Thursday.
She said they stole things and spent time in foster care. No one pressed her to talk, he said, adding that Federal Bureau of Investigation agents and doctors advised them to let her speak when she's ready. Investigators were still interviewing her, and she was "doing as well as circumstances allow", he said.
He had no criminal record, according to the sheriff.
The few neighbours who know Patterson's family say he grew up in a cabin in a remote development that's a mix of seasonal and year-round homes about 10 miles (16 kilometers) outside Gordon proper.More news: Australia shuffle pack for Sri Lanka Test series after India batting failures
