Three Arrested in Child Predator Operation 

Larimer County Sheriff’s Office investigators arrested three men during an operation to fight child prostitution. 

In late May, LCSO investigators conducted an undercover operation. Using online forums, men solicited sexual services from investigators posing as underage sex workers. Several hundred people responded to the postings and expressed interest in buying sexual services from children. Three men ultimately arrived at the agreed upon location, where they were met by law enforcement. They were arrested on the following charges:

“Over the past year, we’ve arrested numerous suspects during undercover child predator operations,” said Undersheriff Joe Shellhammer. “Our investigators work countless hours to catch those trying to prey on the innocent. We’re doing everything in our power to stop this kind of crime in Larimer County.” 

The charges are merely an accusation, and the defendants are presumed innocent until, and unless, proven guilty.
