A former Mansfield youth pastor was arrested Thursday on 10 sex-related felonies reportedly involving a teenage parishioner.

John Picard, 40, of Springboro, was charged with 10 counts of sexual battery, all third-degree felonies. He is accused of having sexual relations with a girl starting in 1992 when she was 13 and continuing until she reached adulthood. Picard was a youth pastor at Grace Brethren Church on Marion Avenue at the time.

Police said they think there are other victims.

“He’s probably one of the most despicable pedophiles that there can be,” Mansfield police Lt. Allen Vandayburg said. “It’s a sad, sad state of affairs when somebody of trust can’t be trusted.”
