Caryn Wyman is the wife of Major Jim Wyman and a drug trafficker exploited because of her addiction. She was a paid mule for Daniel and Rosa Alvarez, but drug dealer Joe Pena killed them and threatened Cary and the people she loves to work for him instead.
Caryn was originally charged with drug trafficking, as well as hesitant to testify due to Pena's threats and the career embarrassment she caused Jim. Jim held no ill will against Caryn and encouraged her testimony, resulting in Pena's successful conviction.
The Wymans were placed in Witness Protection after the trial. (L&O: "White Lie")
