Michael Ray Hill, 28, of Tucson, was booked into the Pima County jail May 2, 2013, and is facing three counts of sexual exploitation of a minor. In January, an Internet service provider notified the National Center for Missing and Exploited Children that someone had used their services to post child pornography online. The center contacted Tucson police, which began an investigation. A search of Hill’s home turned up three images of child porn. Tucson police said the investigation also revealed that Hill may have been communicating with underage boys online.
