An Anchorage man charged with child pornography offenses last year has received a seven-year federal prison term.

U.S. Attorney for Alaska Bryan Schroder's office says Michael John Collier, 32 was sentenced Thursday by Chief U.S. District Judge Timothy M. Burgess. Collier had pleaded guilty in February to one count of sexual exploitation of a child through distribution of child pornography.

The investigation that led to Collier began in February 2018, when Anchorage police got a tip from the National Center for Missing and Exploited Children that a person using the screen name "TorPedo" had an Alaska IP address and was exchanging pictures of child sexual exploitation on social media. The IP address led to Collier, and a search warrant served by APD recovered devices that had thousands of images and videos showing children being sexually exploited.

According to a statement from Schroder's office, Collier told law enforcement that "TorPedo" was one of his user names and that it stood for "Tor" (the anonymizer software for Internet users) and "Pedo" (short for pedophile). Collier also told law enforcement his pornography collection included images of kids between 11 and 13 years old and toddlers.

In addition, Collier also admitted he had started to follow young girls on social media and had started exposing himself to kids, both in person and online. Law enforcement said Collier talked about how to look at a manual on how to exploit children without getting caught.

The case was investigated by the Anchorage Police Department and the Federal Bureau of Investigation as part of Project Safe Childhood started by the Department of Justice to fight the epidemic of child sexual exploitation and abuse.  The Project Safe Childhood website offers links to help and resources for victims and survivors of child sexual abuse.

Collier's sentence includes a lifetime of supervised release after his prison term.
