Case Summary
Joanna Hunter was found dead in 2011 in her home in Vacaville, California, in an apparent suicide by hanging.

Mark Lewis was not charged for Joanna's death but later convicted for unrelated violent crimes. The case influenced the creation of Joanna's Law to improve death investigations involving domestic violence.
