A Tucson man, who was a convicted felon, was sentenced in federal court Tuesday to 18 years in prison for accessing child pornography.
Billy Dewayne Mills, 34, pleaded guilty to knowingly accessing child pornography on March 7, states a news release from the U.S. Attorney's Office.
Once released from prison, Mills will have a lifetime term of supervised release with stringent sex offender conditions, including registration as a sex offender, according to the release.
After an investigation by Tucson agents of the Department of Homeland Security, Mills was indicted by a federal grand jury for accessing child pornography.
Investigators found out that Mills downloaded and shared child pornography through a sharing program, states the release.
In 2008, Mills was convicted in Missouri of possession of child pornography and in 2000 of first-degree child molestation, according to the release.
Mills case was investigated under Project Safe Childhood, a nationwide initiative by the Department of Justice to combat child sexual exploitation and abuse.
The project coordinates federal, state and local resources to locate, apprehend and prosecute persons who exploit children via the Internet, and identify and rescue victims.
