Arizona Man, Donald Edward Cobern, Sentenced to 15 Years in Prison for Sexual Exploitation of Minor

PHOENIX, AZ (STL.News) Arizona Attorney General Mark Brnovich announced 63-year-old Donald Edward Cobern, of Tucson, was sentenced to 15 years in the Arizona Department of Corrections for Sexual Exploitation of a Minor, to be followed by lifetime probation.  Cobern, a registered sex offender who was previously convicted of First Degree Child Molestation in Washington State, pleaded guilty to three counts of Sexual Exploitation of a Minor earlier this year.

In February of 2019, investigators with the Arizona Attorney General Special Investigations Section and the Tucson Police Department received a tip from Microsoft that a computer in Tucson had used Microsoft services to view child pornography.  Based on that tip, investigators traced the computer to Cobern.  When they searched his apartment, investigators found a desktop computer, two flash drives, and an external hard drive.  A forensic analysis confirmed that these devices collectively contained hundreds of images of child pornography.
