David Glass is a musician and entrepreneur on the radar of mother-daughter con artists Lorraine Dillon and April Troost, along with occasional associate Patrick Sullivan. In a fraudulent "investment", the trio set up a con where the two women pretended to "shoot" Sullivan and blackmail Glass into accepting the "deal".
Glass was eventually defrauded out of $500,000, and when Troost sells Dillon out for Troost's own killing of Sullivan and gets away with the money, Glass commits suicide by hanging out of despair. (L&O: "Flaw")
