Missouri ? A former pizzeria manager accused of abducting two boys pleaded not guilty Monday to kidnapping, sexually abusing and trying to suffocate the one he is suspected of holding for four years.

Michael Devlin, 41, clean-shaven and thinner since he was arrested in January, heard the charges against him from a jail cell in Potosi via a closed-circuit video feed. He stared into the camera and showed no emotion as he listened to the allegations that he sexually abused and tried to kill Shawn Hornbeck in October 2002.

Shawn, now 15, was 11 when he was taken while riding his bike near his home in Richwoods, Mo. In January, authorities searching for another missing boy, 13-year-old Ben Ownby, found both boys in Devlin’s apartment.

Ben, of Beaufort, Mo., had been missing for four days after being abducted shortly after getting off a school bus.

Devlin faces charges including kidnapping and forcible sodomy in three Missouri counties, plus federal charges of pornography and transporting a boy across state lines.
