An Evans City man accused of photographing and videotaping a 14-year-old girl during a yearlong course of sexual assaults will likely spend 8 years in prison.

Stephen R. Sahady, 26, pleaded guilty to statutory sexual assault and possessing child pornography.

His plea arrangement with the Butler County District Attorney's Office calls for a sentence of 8 to 16 years in state prison, according to court records,

However, as a special condition of the plea arrangement, prosecutors agreed if Sahady is well-behaved in prison, they will not object to his release on parole after he serves the minimum eight years.

Sahady is to be sentenced July 8 by Butler County Judge Timothy McCune. However, the defendant must first be evaluated by a member of the state's Sexual Offender Assessment Board.

Court records say Stephen Sahady began assaulting the girl in August 2008 and the incidents increased in frequency until July 2009, just before Sahady's wife, Chantal Sahady, reported the activity to Cranberry Township police.

After that report, investigators allegedly recovered images and videos from Sahady's home computer of the girl and Stephen Sahady engaged in sex acts as well as acts of bestiality.

Multiple charges of conspiracy and engaging still pend against Chantal Sahady, 24, for her alleged role in the assaults.

Court records allege Chantal Sahady picked up the victim, a Cranberry girl, and brought her to the couple's home.

Court records allege Chantal Sahady told investigators she was aware of some of her husband's activities with the girl and even began participating a few times. But Chantal Sahady allegedly told investigators she became uncomfortable and left the room.

Chantal Sahady is scheduled to appear in court July 20.
