Police on Thursday arrested a Cary man accused of possessing multiple pornographic images of young girls. Sean M. Keady, 25, of the 400 block of Redwood Drive, is charged with three counts of possession of child pornography. Each count carries a potential six- to 30-year prison sentence if he were convicted. Keady's arrest was the result of a nearly yearlong police investigation, according to a news release the Cary Police Department sent Friday. The Internet Crimes Against Children Task Force notified Cary officers in March about a social media account sharing photos believed to contain child pornography, according to the news release. Police used search warrants to seize Keady's electronic devices, which were then sent to the FBI’s Regional Computer Forensic Laboratory.
