On Thursday, after being missing for close to three months, Jayme approached a stranger near the small, isolated north woods town of Gordon, Wisconsin and pleaded for help.
Authorities believe Patterson went to the Closs home intending to kidnap Jayme. He was jailed on suspicion of kidnapping and homicide.
Closs was targeted by suspected kidnapper Jake Patterson, 21, who carefully planned her parents' murder, even shaving his head to avoid leaving forensic evidence at the crime scene, Mr Fitzgerald told reporters on Friday.
Smart said in an interview that Closs' story is "why we can never give up hope on any missing child".
The grandfather of a Wisconsin teen abducted during a home invasion that left her parents dead says the suspect had no connection with the family. She said if she could pass one piece of advice on to Jayme, it would be to take time to heal and have faith that she will be able to process the hard emotions that follow such an experience.
The sheriff said he didn't know whether Jayme had been physically abused.
"I'm lost and I don't know where I am, and I need help", Jayme told Nutter, the woman told the station.
"It's a awful feeling when you don't know where your kid is but I don't know how I would react if I was to have mine walk through that door".
"We don't really know what shape she's in", he added.
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". She said they stole things and spent time in foster care.
Jake Thomas Patterson, 21, who allegedly killed two people and held their daughter captive for three months.
Storm Punishes Swath of US With Snow, Ice and Freezing Rain
Louis residents are digging out from a major snowstorm that buried the region with almost a foot of snow over the weekend. In Indiana, one person was killed in a crash on Interstate 70 in Greenfield on Saturday, according to WISH-TV .
The news that Jayme was safe set off joy and relief in Barron, which has a population of 3300.
Jayme's aunt, Jennifer Smith, posted the photos on Facebook.
The neighbour had been walking her dog in the area, a subdivision known as Eau Claire Acres, when a teenage girl came up to her in the cold and asked for help.
"And I would tell her that this experience might feel like it's defining, it might feel like that's who she is now, but it doesn't have to be", Smart said.
As Jayme begins to process her trauma, experts and former victims say what she needs most is space and time to discuss it on her own terms.
Smart called Closs fearless, strong, and a powerful survivor - but also says there is a long road ahead.
Another aunt, Sue Naiberg Allard, posted that Jayme got "the most awaited hug ever" when she returned home. "She did not talk about why or how. She said she did not know him".
Patterson surrendered peacefully and was arrested "just down the road from the residence" Closs Douglas County Sheriff Thomas Dalbec previously said.
There is no evidence in the early stages of the investigation that links Patterson to the parents or to Jayme, Fitzgerald said.
"I don't understand it yet myself", Fitzgerald said.
Despite Erik Patterson's criminal record, few across the township seem to have heard of his family.
The disappearance of Jayme Closs has captivated the country.
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.
