One of the people who encountered missing Wisconsin girl Jayme Closs described what happened Thursday, when the nationally-watched case came to a dramatic conclusion

Peter Kasinskas said on "America's Newsroom" Friday that Closs flagged down a woman who was walking her dog near his house in the small town of Gordon, Wisconsin. 

Closs, 13, who had been missing since October, was dirty and malnourished after reportedly fleeing from a residence nearby. The dog-walker immediately knocked on Kasinskas' door and they called 911. 

A 21-year-old man was arrested shortly after Closs was found, and police identified him Friday as Jake Thomas Patterson. He is being held on charges of murder for the killings of Closs' parents and kidnapping. 

Kasinskas told Sandra Smith that Closs "did not know" her male captor before she was kidnapped. Closs vanished Oct. 15 after her parents were fatally shot in their home in Barron County, which is about 65 miles from where she was found in northern Wisconsin. 

"She told us his name and what color his car was," Kasinskas explained, adding he knows who the suspect is but does not know him "personally."

Kasinskas said Closs looked just like the pictures released by authorities but thinner, and it appeared that she was not able to take care of herself in the nearly three months since her abduction. 

He said Jayme relaxed quickly and played with their new puppy, but did not say much. Kasinskas said he was cleaning fish from a daytime fishing trip when he and his wife heard the unexpected knock on the door. 

Authorities said Patterson took proactive steps to cover his tracks at the crime scene and hide his identity from the general public. 

Barron County Sheriff Chris Fitzgerald said Friday that Patterson did not have a prior criminal history, did not have previous contact with the Closs family and deliberately targeted Jayme Closs.
