A Mishawaka man is charged with three counts of possession of child pornography and one count of child exploitation after police say they found hundreds of child pornography pictures on his laptop.

William Evans Jr. was arrested Wednesday and posted $5,000 bond on Thursday, WNDU reported. 

A St. Joseph County cybercrimes investigator downloaded a file containing child pornography from an IP address police eventually tied to Evans’ computer, WNDU reported. When police executed a search warrant at his home weeks later, they found 500 files of pornography on the computer.

Evans faces up to 13 ½ years in prison if he’s convicted of all four charges.
