Court documents reveal new details in the case of a 29-year-old Mountlake Terrace man arrested Thursday morning for sexual exploitation of minors.
The suspect, who will not be named until he is formally charged, was discovered through a sting operation by the Homeland Security Investigations (HSI) Team. Court documents show a HSI agent joined a peer-to-peer file sharing network in November 2015 claiming to be seeking child pornography. The suspect told the undercover agent he had some, but wouldn’t share it.
The HSI agent requested the subscriber information from an internet provider for the IP address of the suspect identified using forensic software. The suspect’s roommate was the internet subscriber at the time.
In October 2016, the agent signed into the undercover account again. He saw the suspect had recently logged into the peer-to-peer file sharing program again. The subscriber information was again requested from the internet provider, court documents say, showing the suspect as the internet subscriber. Investigators determined his old roommate had moved out.
In early December, the suspect’s account was again listed as “active” on the peer-to-peer file sharing network. A search warrant was issued on Dec. 14 and served on Dec. 15.
Court documents state that the suspect admitted to the agent that he had sexually explicit photos of children that he downloaded from the internet. He also admitted to having the username on the peer-to-peer network that the agent engaged with in 2015.
During the search, an external hard drive was found in his residence containing several images of minors in various sexual situations, some victims as young as 4 to 6 years old.
He was booked into the Snohomish County Jail for possession of child pornography.
