The Douglas County Sheriff’s Department in Wisconsin notified the Barron County Sheriff’s Department on Thursday that they had located Jayme alive.
She was found Thursday afternoon in Gordon, Wisconsin, a town about 66 miles north of where Jayme was last seen, the Douglas County Sheriff’s Office said.
A suspect was taken into custody about 10 minutes after authorities found Jayme, the sheriff’s office said.
No more details were immediately available but authorities have said they will hold a news conference Friday morning.
Jayme’s aunt, Sue Allard, said her niece was in the hospital Thursday night.
Jayme vanished October 15, and her parents, James and Denise Closs, were found fatally shot in their home near Barron, a town of 3,300 in northwestern Wisconsin.
Police arrived to find the door kicked in but no one was there. Investigators said they believed Jayme was at home during the shooting.
“Finally we want to especially thank the family for their support and patience while this case was ongoing. We promised to bring Jayme home and tonight we get to fulfill that promise. From the bottom of my heart THANK YOU!” Barron County Sheriff Chris Fitzgerald said in a statement.
“This case has been very trying on the family so please respect their privacy and we reunite them later tonight.”
Thousands of people joined search parties for months as investigators received thousands of tips. The FBI offered a cash reward for information on her whereabouts and hunters in the area were also urged to be on the lookout for clues.
In the days after Jayme’s disappearance, law enforcement officials assured the public they believed she was alive and in danger.
Another of Jayme’s aunts, Jennifer Smith, pleaded with those who knew where the girl was to contact the sheriff’s department.
“Jayme, we need you here with us to fill that hole we have in our hearts,” Smith said more than a week after the girl went missing. “We all love you to the moon and back. And we will never stop looking for you.”
