A Puyallup man accused of having 100,000 images of child pornography on his computer pleaded guilty Thursday.
John Graff, 56, is charged with first-degree possession of child pornography.
Puyallup police started investigating him March 19, based on a tip from the National Center for Missing and Exploited Children.
Microsoft Skydrive reported a cloud account under Graff’s name that contained child pornography between Feb. 28 and May 14, when police followed up on the report and he was arrested.
Images were also found on an external hard drive at his home.
His sentencing is scheduled for Sept. 18.
