A Roseville man was sentenced to seven years in prison for possessing child pornography.
Daniel Harrison McGrath, 60, was found with more than 3,000 images and videos depicting child porn, the U.S. Attorney's Office for the Eastern District of California said.
Court documents said some of the images showed prepubescent children and infants in "sadistic and masochistic conduct."
The attorney's office said during an unrelated investigation, McGrath told investigators that he had child porn on his computer. When officers searched his computer, they found the videos and photos, court documents said.
