Case details
What we know:
According to the criminal complaint against Liepert, a Waukesha police detective made contact on Nov. 24, 2024 with a 16-year-old juvenile victim. That person reported he had communicated with an adult male via an app called "Sniffies" between February and March 2024. That teen had also communicated with the same person on Snapchat and Telegram. The victim described the adult male "as a married, Lutheran school teacher," the complaint says. The teen indicated he met with the defendant "about three or four times," the complaint says.
When the detective checked the defendant's Snapchat account, it was discovered that "he is a teacher at a Lutheran school." The complaint goes on to say "records showed the user explaining that he teaches 9-12 grade at a private school." It also shows "the defendant's receipt of several sexually explicit videos" from the teenage victim," the complaint says.
The detective interviewed the defendant on Feb. 13, 2025. The defendant advised he has a Snapchat and Sniffies account. The defendant indicated he did not have his Sniffies account because he deleted it a few weeks prior, the complaint says.
