ST. LOUIS (AP) — Michael Devlin received one final sentence Friday — 170 years — for making pornography of a boy he kidnapped and sexually assaulted over four years.

Devlin is already serving multiple life terms for kidnapping and assaulting Shawn Hornbeck and another Missouri boy, Ben Ownby. This time around, a federal judge went well beyond the sentencing guideline of 30 years.

The sentence came on a guilty plea in October from Devlin to four counts of making pornographic photos and videotapes of Shawn, who was abducted at age 11 in 2002, and two counts for taking Shawn across state lines on trips to Illinois and Arizona with the intent of sexually assaulting him.

The Associated Press generally does not identify victims of sexual assaults, but the identities of Devlin's victims became widely known in the coverage of his arrest and prosecution.

Devlin, 42, was sentenced to multiple life sentences in October after admitting to crimes in Franklin, Washington and St. Louis counties connected to the abductions of Shawn and 13-year-old Ben Ownby in January. Both boys were found four days after Ben was abducted at Devlin's apartment in the St. Louis County town of Kirkwood.
