A western Nebraska man and convicted sex offender has been sentenced to 10 years in federal prison for possessing child pornography.

Federal prosecutors say 38-year-old Bobby Joe Ansley, of Mullen, was sentenced Friday in Lincoln’s federal court.

Prosecutors say the Nebraska State Patrol received tips in February 2016 about images of sexually explicit conduct involving minors being attached to Ansley’s email address. After investigation, the patrol searched Ansley’s home and seized an external hard drive that held 1,950 images of child pornography, many including prepubescent children.

Ansley had previously been convicted in 2003 of aggravated sexual abuse in California.
