There's no evidence Patterson knew the Closses or had previous contact with them, the sheriff said.
He had dressed in a black jacket and black mask, shaving his face and head to avoiding leaving any physical traces at the scene. "We have to take little steps".
She was found in northern Wisconsin last Thursday after fleeing the home she had allegedly been kept in.
As Jayme Closs starts her road to recovery following her kidnapping, investigators are trying to piece together what happened during the almost three months she was in captivity. She put on a pair of his shoes and walked outside, where she encountered the woman walking her dog. But Patterson's attorneys have been lauded for taking high-profile cases with a special emphasis on sexually violent people, according to a state public defender office news release from February 2018. Her grandfather, Robert Naiberg, told The Associated Press that Jayme told Federal Bureau of Investigation agents she did not know Patterson at all.
She and her mother, Denise, hid in the bathroom. They heard a gunshot, and Jayme knew that James had just been killed, according to the complaint.
Mr Patterson, who was dressed head to toe in black, taped Jayme's hands and ankles and dragged her out to his auto where he threw her in the boot. He threw her in the boot and drove away as sirens began to sound, the complaint said.
The man accused of kidnapping a 13-year-old Wisconsin girl Jayme Closs, after killing her parents, and holding her hostage for months, sometimes under his bed, told police he had picked his victim at random, prosecutors say.
At that moment, he said, "he knew that was the girl he was going to take", said a criminal complaint filed on Monday.
Patterson was charged Monday with kidnapping and with killing Jayme's parents.
Smith posted photos to social media of Jayme smiling with her dog and her aunt.
Denise Closs complied and then Patterson shot her, the complaint said.
Patterson was charged on Monday. Jayme's parents were shot to death and the teenager vanished the same day.
Officials and loved ones have said they will give Jayme all the time she needs to share details of her story, which Smart agreed is the best course of action.
The girl allegedly "described how, on one occasion, Patterson got mad at her and hit her "really hard" on her back with what she described as a handle for something used to clean blinds and that it hurt really bad when Patterson hit her with it".
Barron County Sheriff Chris Fitzgerald says Patterson will appear via video from the Barron County Jail.
"I have to pinch myself", Allard said.
There is no evidence in the early stages of the investigation that links Patterson to the parents or to Jayme, Fitzgerald said. He decided then and there he would kidnap her, but abandoned two attempts before October 15 because there either were a lot of cars at her residence, or the lights were inside in the house.
It's unclear exactly what Closs experienced - including whether she was coerced with threats or physically abused - so people must be careful how they interact with her, said Duane Bowers, a trauma therapist who works with families of missing and exploited children and adults.
Nutter and Jayme went to the closest house, the home of Kristin and Peter Kasinskas.
