They noted that multiple other agencies were assisting, including the Walworth County Sheriff's Office, Wisconsin Department of Justice, the Town of East Troy Police Department and Milwaukee Police Department.
A suspect has been taken into custody in regards to the case, according to the Barron County Sheriff.
Jayme Closs, the 13-year-old Wisconsin girl who was declared "missing and endangered" after her parents were found dead in their home in October has been found.
Gordon lies about 40 miles south of Lake Superior and about 65 miles north of Barron, Jayme's hometown. We also could not have endured this case without the support of the public and I want to thank them for all the support and help. Investigators believed Jayme was kidnapped before her parents were gunned down in their home.
In the 20 minutes Jayme was in their home, Kasinskas and her husband, Peter, tried to make her feel more comfortable, they said.
Trump urges wall funding to fix border crisis in Oval Office address
Some say Trump's hardline policies are slowing processing for migrants, creating an overwhelming bottleneck at the border. And it seems that this development did not escape the watchful eye of political commentator Ben Shapiro as well.
The Douglas County Sheriff's Office posted on their Facebook page late Thursday thanking "the citizen who phoned in the information".
Jayme Closs is seen in an undated photo released October 15, 2018, by the Barron County Sheriff's Department.
Jayme was skinny and dirty, wearing shoes too big for her feet, but appeared outwardly OK when she was discovered Thursday afternoon near the small town of Gordon, the neighbors said. "And I just shut myself totally down". From the bottom of my heart THANK YOU!' She asks people to continue to pray for "Jayme's well-being and our families healing".
The caller didn't communicate with police, but noises heard in the background suggested a disturbance or struggle of some kind.
Jayme's name was added to the top of the FBI's Missing Persons list and has been on digital billboards across the nation since she vanished four months ago.
The child's disappearance made national news, sparking massive searches, with 1,500 volunteers scouring woods and fields in suburban Minneapolis, and the offer of a US$25,000 (S$33,700) reward for her safe return.
