Marie Greevey is the wife and later widow of Detective Max Greevey. She keeps a friendly relationship with Max's partner, Detective Mike Logan, and is the mother of their three children. Marie personally witnessed her husband get forced onto his knees and shot dead in the rain by Daniel Magadan, Jr., just outside the family's home, all over the case Greevey and Logan were investigating at the time.
Marie was in the gallery during Magadan's trial and emotionally watched as the jury found him guilty of first-degree murder and the judge handed down a 25-to-life sentence. (L&O: "Confession")
