It’s been more than four years since Sarah Boone became known as the alleged “suitcase killer.” Now, ahead of her murder trial, she wants a judge to let her lawyer rely on so-called battered spouse syndrome as his defense – something prosecutors are taking serious issue with.

Ms. Boone is currently facing a second degree murder charge after her late boyfriend Jorge Torres Jr. was found dead zipped inside a suitcase outside the home they shared at Winter Park, Florida. She has previously claimed the tragedy resulted from drunken hide-and-seek gone wrong, but now she wants to rely on battered spouse syndrome in her defense.
