Authorities have arrested a 70-year-old man on child pornography counts. The Advocate reports William J. Nason of Denham Springs was booked Wednesday on 20 counts of pornography involving juveniles. Police say a search of Nason's home turned up hundreds of images of child pornography on electronic equipment. Nason is being held in the Livingston Parish Detention Center in lieu of a $2 million bond. It was unclear whether he has an attorney.
