NOBLESVILLE, Ind. -- A Hamilton County child protective services worker who already faced sex-related charges involving two boys has been charged with molesting a third.

Cory Heinzman, of Arcadia, was charged this week with molesting an 11-year-old boy on three occasions in 2002.

Heinzman was arrested in May on charges that he molested an autistic teenage boy who had been part of his caseload. Authorities said molestation in that case allegedly happened between August 2004 and March.

In June, he was charged with having sexual contact with a second boy late last year. That boy made the allegations after the first investigation started.

Heinzman was placed on unpaid administrative leave. He is free on bond and is prohibited from having contact with the three boys.
