SAUK COUNTY, Wis. — The search for James Yoblonski is continuing nearly a month after he was first reported missing, the Sauk County sheriff’s office said.

Yoblonski is 13-years-old, weighs 120 pounds and is 5’11”. He has a half-inch scar on the back of his neck, blue or green eyes and brown hair.

Yoblonski was first reported missing June 12. On Monday, Sauk County Sheriff Chip Meister said “this case is still an active investigation and all avenues are being looked into.” Meister said several investigators have been assigned to the case; they are continuing to work through tips and leads, conduct interviews and analyze electronic information, he said.

Authorities said they initially believed Yoblonski could be near Devil’s Lake State Park. He was last seen wearing red shoes, blue jeans, an unknown shirt and baseball hat. Officials said Yoblonski left his home overnight in a family vehicle. That vehicle was found on U.S. Highway 12.

Law enforcement and Yoblonski’s family have conducted several searches of the highway area since June 12. Meister said law enforcement has also searched “several other locations that were believed to be areas of interest.”

“We will continue this investigation until it is resolved,” he said.
