A campground owner's arrest in connection with the alleged sexual assaults of several boys and young men has local investigators concerned that more victims may be out there.
Brian J. Miller, the owner of Kastle Kampground, was arrested Friday evening in Dane County and is being held at the Dane County Jail.
Kastle Kampground, N11301 Kinney Lake Road, is a popular spot on Lake Kinney, which is near Marion in the Township of Dupont, Waupaca County.
The investigation started June 28 after deputies were called to an underage drinking party at the campground, WISC-TV reported.
"It grew, and kind of spider-webbed out to a lot bigger case when we investigated that," said Sheriff Brad Hardel.
Deputies said they learned through questioning that two of the young men involved claimed to have been sexually assaulted by Miller.
There are now three known male victims who were allegedly assaulted by Miller at the campground and in the Madison-area, where Miller owns a home, WISC-TV reported.
"The current victims that we're aware of range from 10 to 21 years of age. And we feel there could be other victims out there who have not yet come forward," said Sheriff Hardel.
Investigators from the Waupaca County Sheriff's Department and the Wisconsin Department of Justice Division of Criminal Investigation, known as DCI, executed several search warrants at the campground Saturday morning. The warrants were issued based on an on-going investigation, according to the Waupaca County Sheriff's Department.
The Dane County Sheriff's Department and the DeForest Police Department are also involved in the investigation.
Investigators believe more victims may be out there and want them to come forward.
Anyone with information should call the Waupaca County Sheriff's Office at 715-258-4466, Waupaca County Crimestoppers at 888-258-9955, or DCI at 920-832-2750.
Miller will face three counts of third-degree sexual assault and one count of fourth-degree sexual assault, according to the criminal complaint.
Kastle Kampground has 700 campsites and was purchased by Miller about a year-and-a-half ago.
