Grube was seen standing naked in his bedroom, watching children and parents during the week of April 8, 2013, as they arrived or left the day care center, his complaint and sheriff’s reports state.

Someone reported seeing Grube watching the children with binoculars, multiple times, while completely naked or nude from the waist down, according to his complaint.

"At least from the reports we've had, no children saw him," Assistant District Attorney Robert Repischak said during Wednesday's sentencing.

"There is no indication he has ever expressed any interest in children," defense attorney Patrick Cafferty said, adding Grube and his wife have since sold their home and moved to Walworth County. "He's been publicly embarrassed by this."

Grube reportedly admitted standing there naked, but said he wasn’t a pedophile and was looking more at the parents dropping off their children. Grube reportedly admitted he became excited knowing someone might see him, according to sheriff’s reports and the complaint. Grube told an investigator he had been exposing himself since early winter.
