The Collin County Sheriff’s Office praised partnering police departments Monday for its part in Operation Medusa, a weeklong multi-agency investigation into the online sexual exploitation of children. A prepared statement from CCSO Public Information Officer Jim Moody said Operation Medusa resulted in the arrest of 15 individuals charged with offenses ranging from the promotion of child pornography to online solicitation of a minor.

The release said in addition to making the arrests, investigators seized hard drives and other electronic devices believed to be used during the commission of the crimes. Once the evidence has been analyzed, Moody said, other offenders might be identified and that might lead to further arrests.

“Sheriff Skinner would like to thank the following agencies for their participation in this operation,” the release said and then listed Sherman PD along with Allen, Dallas, Frisco, Garland, Grand Prairie, McKinney, Mesquite, Murphy, Plano, and Wylie police departments. Also, the sheriff thanked the Collin County District Attorney, the FBI, Texas Department of Public Safety and the United States Attorney’s Office in the Eastern District of Texas.

“Operation Medusa is an excellent example of federal, state, and local law enforcement agencies working together to bring to justice those predators who seek to harm our children. To be clear, if you traffic or trade in child pornography, or you come to Collin County with the intent to have sex with a child, know that we are hunting for you. We will protect our children,” the statement said.
