OKC Man Sentenced To 60 Years In Prison For Advertising Child Porn

An Oklahoma City man has been sentenced to 60 years in prison for advertising child pornography.

According to U.S. Attorney Sanford C. Coats, Mark Edward Hamme, 45, advertised access to a child porn trading network that he moderated for several years.

In order to gain access to Hamme's network, prospective members had to email him child pornography in the amount of 25 pictures or a video in excess of one minute.

Hamme was interested in child pornography depicting young boys, according to authorities.

At sentencing, the court considered evidence that Hamme was a serial predator, whose victims included infants, toddlers, and preteens of both sexes.

Hamme was indicted on February 19, and pled guilty on April 29.

Hamme faced a heightened maximum sentence of 60 years' imprisonment because at the time of his federal offense, he was already a registered sex offender due to Cherokee County convictions for molesting children.
