SAN ANTONIO —  A 27-year-old woman has been arrested on charges of distributing harmful material to a minor after a 14-year-old's parents found a topless photo of her on his cell phone.

Victoria Ann Chacon, a former middle school teacher, allegedly met the boy at their church, where she was a Sunday school teacher. Authorities at Somerset Independent School District said they found no evidence of any inappropriate relationships with students; the 14-year-old attended school elsewhere.

The boy's parents called police in March after finding racy letters in which Chacon professed her love. The boy initially refused to give a statement about the relationship, the arrest warrant says.

Several months later, the parents found a cell phone with a topless photo of Chacon. The phone was owned by Chacon and the two had been calling on another, according to court documents.

The woman was arrested Tuesday. Jail records had no attorney listed for her.
