A Wasilla man will serve more than a decade behind bars for secretly filming children using the bathroom inside his own home. 

Tyler Arlan Weis, 41, was sentenced Monday to 12 years in prison and a life-term of a supervised release. 

While investigating a file-sharing network online, Alaska State Troopers downloaded multiple files from Weis' computer. Among those files, the U.S. Attorney's Office says, were images of adults sexually assaulting prepubescent females. 

When searching Weis' home, troopers found more child pornography on his computer. 

Further, multiple hidden camera videos were found that showed minors using the bathroom inside Weis' home. 

Chief U.S. District Judge Timothy Burgess described Weis' crime as "extremely serious" and noted the "profound" effect the images and videos had on their victims. 

The images "depicted serious, disturbing, heinous violations that children in the video suffered," Burgess said. The hidden camera videos produced be Weis were "even more troubling" because "the activity occurred in his own house."
