PORTLAND - The US Department of Justice says a man "sexually fixated on children" has cut off his GPS monitoring ankle bracelet and fled his Portland home.

Paul Eric Presley, who is 47, faced up to 71 months in prison but failed to show up for sentencing in U.S. District Court in Tacoma, Wash. Monday.

Vancouver police and the FBI said the evidence against Presley included more than 7,000 child pornography images and several hundred movie files of children engaged in explicit sexual conduct.

In 2006 Vancouver police responded to a 9-1-1 call at Presley's home. His wife told officers Presley had child pornography stored on his desktop and laptop computers.

Officers seized the desktop computer. The next day Presley's daughter and her boyfriend delivered the laptop to police.
