 County police say 24-year-old Alanis Pignon was arrested yesterday following an investigation. She's charged with sexual solicitation of a child under 18, endangering the welfare of a child and indecent exposures. She's being held at the Baylor Women's Prison. County police say there is concern there could be additional victims who have not yet come forward. Police say Pignon used Snapchat to communicate with her students, one of whom received sexually explicit photographs. The Catholic Diocese of Wilmington has cooperated in the investigation.
