Jayme Closs was discovered by the Douglas County Sheriff's Department in Gordon, Wisconsin, a town about 65 miles north of where she was last seen.
A suspect has been taken into custody, Barron County Sheriff's Department announced.
Jayme Closs was abducted from her home in Barron, Wisconsin on October 15, the same day the teenager's parents, James, 56, and Denise Closs, 46, were found shot dead inside.
"I heard she escaped and found a woman walking with a dog and asked for help and that's all I know", Sue Allard, Jayme's aunt, told KMSP.
The Barron County Sheriff's Department confirmed Thursday evening that Jayme has been located in Douglas County, and an unidentified male suspect has been arrested.
Jayme Closs, 13, was found and a suspect was taken into custody a short time later, according to the department.
At a news conference, police said they had received about 400 tips from the public since the 13-year-old disappeared and an Amber Alert was issued for her. There are no other details on the case at this time due to a fluid and active investigation. Described as "5 feet tall and 100 pounds with strawberry-blond hair and green eyes", Jayme Closs is an 8th grader at Riverview Middle School in Barron.

Kristin and Peter Kasinskas say their neighbor had a skinny, dirty girl with matted hair standing next to her.
In the 20 minutes Jayme was in their home, Kasinskas and her husband, Peter, tried to make her feel more comfortable, they said.
Searches of her social media, cell phone and computer have offered no evidence of a boyfriend or anyone she met anyone online who might have targeted her or her parents.
WCCO-TV's Mary McGuire spoke to Jayme's aunt Sue on Thursday evening, who said her niece was now in the hospital.
"The family would help anyone, anytime, with anything they needed". "It's unbelievable. It's like taking a big black cloud in the sky and getting rid of it and the sun comes out again". "I think everybody wishes her a good recovery and a happy life going into the future". County buildings dedicated Christmas trees to Jayme, decorating them in her favorite colors and the word "Hope".
When they arrived they couldn't find a gun, and Jayme had gone missing.
