Twenty-one dangerous sexual predators who targeted children in Pierce County were removed thanks to a multi-day operation run by the Washington State Patrol (WSP), and several local law enforcement partners and affiliates. Dubbed “Operation Net Nanny,” this was the 13th operation around the state with a mission to proactively target those persons involved in child abuse and child exploitation via the internet. In addition to the identified suspects, Detectives believe four suspects have been recognized as having access to over 10 children at risk of being abused. Supplemental follow-up investigations are currently underway to identify those children and arrange for the appropriate assistance for any abuse they may have been exposed to.

The Net Nanny operations began in August of 2015 by the Washington State Patrol (WSP). Since the original operation, there have been twelve additional operations throughout Washington State. The WSP Missing and Exploited Children Task Force (MECTF), an Internet Crimes Against Children (ICAC) affiliate, spearheads the multi-agency operation that includes partners in federal, state, and local law enforcement.

The “Net Nanny” series, conducted throughout the State of Washington, has now netted a total of 205 arrests and rescued over 30 identified child victims throughout the state.

“While the Internet is a powerful tool for our nation, criminals using it to target our communities’ necessitates a need for this type of proactive investigations by our law enforcement troopers and partners in order to combat these horrible crimes,” says WSP Chief John R. Batiste. “This operation is protecting our vulnerable children and making communities safer.”

Undercover Law enforcement officers communicated on the internet through various websites and mobile phone applications with people interested in having sex with children. The operation generated hundreds of responses. The would-be perpetrators who were arrested over the five day operation traveled to meet with undercover detectives posing as young girls and boys with the intent to engage in sexual activity with children as young as nine years old.
