A Houston man named John Henry Skillern was arrested after Google alerted authorities about illegal photos of children in his Gmail account. The 41-year-old, who works at a Denny’s restaurant in Pasadena, is a registered sex offender, convicted of sexually assaulting a child in 1994. The search giant informed the National Center for Missing and Exploited Children after detecting three allegedly pornographic images of children in Skillern’s email. The Center then alerted the police, which in turn used the information to get a warrant. According to the police, the raid yielded more than what Google knew was there.
