SEASIDE, Ore. (AP) — A Seaside man was sentenced to 20 years in prison Friday for encouraging child sex abuse.

Joshua Allen Pickering, 36, pleaded guilty to eight counts of encouraging child sex abuse in the second degree. He was originally charged with 18 counts of possession of child pornography, The Astorian reported.

Pickering has a long criminal history in Clatsop County, including numerous arrests and charges related to sex abuse and assault.

District Attorney Ron Brown argued that Pickering is anti-social and has not been open to treatment. Jail staff described Pickering as challenging to work with and volatile.

Pickering’s attorney described a childhood of abuse and unstable housing beginning when Pickering was removed from his home at age 9. He said in court that he does want to be a better person.
