Ann Carter is the ex-wife of Bill Carter, who consulted with divorce lawyers Fred and Lizzy Bellamy. The Carters not only had a suicidal son, David, but they were holding captive a Haitian girl named Isabel they abused as a child slave. Ann used that for the divorce going in her favor, but the Carters couldn’t prevent Isabel being returned to Haiti once they were found out.
As the Bellamys were starting an investigation to dismantle the trafficking ring, they were killed in their home to silence them. The Carters were originally suspected of sexual abuse of their kids, until the ring was found, and the operators, Miriam and Eric Johnson, and all their accomplices were arrested to rescue all the remaining kids.
The Carters were cleared on suspicion of murder but imprisoned for child trafficking and abuse. (L&O: "Chattel")
