A Washington County man has been sentenced to 29 years in federal prison after admitting he sexually abused a girl and coerced her into sending explicit images. William R. Murphy, 41, received the punishment in U.S. District Court in St. Louis on April 29, closing a case prosecutors say involved both threats and sexual contact with a juvenile.

Guilty plea and charges

Murphy pleaded guilty in January to one count of production of child sexual abuse material and one count of coercion and enticement of a minor, according to a press release from the U.S. Attorney's Office for the Eastern District of Missouri. Prosecutors said Murphy admitted engaging in sexual contact with the victim when she was between 13 and 17 years old and at times threatened her to obtain explicit images.

The plea paperwork showed both sides agreed to recommend a 27-year term at sentencing, a substantial stretch that still fell short of the maximum penalties on the table.

Judge imposes 29-year term

Instead, the court went higher. U.S. District Court handed down a 29-year sentence on April 29, as reported by First Alert 4. That term exceeded the recommendation in the plea agreement. The local report did not include the judge's explanation for the longer sentence, leaving the reasoning on the record but out of public view for now.

Investigation and federal program

The Washington County Sheriff's Office led the investigation in partnership with the FBI, according to the U.S. Attorney's Office. Prosecutors identified the case as part of Project Safe Childhood, a U.S. Department of Justice initiative that pulls together federal, state and local resources to pursue child exploitation crimes. Assistant U.S. Attorney Jillian Anderson handled the prosecution.

Legal context

The charges Murphy admitted carry some of the stiffest penalties in the federal criminal code. Production of child sexual abuse material under 18 U.S.C. § 2251 carries a mandatory minimum of 15 years and a maximum of 30 years. Coercion and enticement of a minor under 18 U.S.C. § 2422(b) carries a minimum of 10 years and up to life in prison. Those statutory ranges help explain why prosecutors were seeking a multi-decade outcome in the first place.

The sentence brings a federal conclusion to a case that investigators say began with threats to a juvenile victim and ended with Murphy's guilty plea earlier this year.
