Oxford, MICHIGAN

"It is one of the more disgusting cases we have seen in some time," said Oakland County Sheriff Michael Bouchard. "Not only do we have a convicted sex offender plying his trade but it appears to be against a school girl with the indifference of a school employee. She should have raised some kind of alarm."

July 2, 2008 - A 64-year-old convicted sex offender and his wife are both expected to face charges Thursday in the sexual assault of a 16-year-old girl who was allegedly paid money to test and rate sexual devices for the man.

The teenager, who attends Oxford schools, was introduced to the man by his wife, who is an Oxford High School teacher, in 2006 when the alleged victim was a freshman at the school, according to investigators. The wife invited her to do household chores for pay. Because of her status as a teacher, the wife is expected to be charged with failure to report child sexual abuse.

The man was sentenced to probation in 2002 for a similar offense in 2001 involving his 14-year-old foster daughter. He was initially convicted of first-degree criminal sexual conduct following an Oakland Circuit Court jury trial but the verdict was dismissed on appeal. He subsequently pleaded no contest to a lesser charge of second-degree criminal sexual conduct, was sentenced to one year in jail (with time already served) and placed on two years probation that expired in 2004.

In the recent case, the teenager has told investigators she was invited over to the house on June 26 and while they watched a movie together he sexually assaulted her. She fled the house and drove home. She later called authorities and reported the incident.

The girl has also reported the man paid her money to test sexual arousal devices and submit a report, including ranking of the items and her experience.

The names are not being released until they are arraigned on Thursday.
