The children of a New York woman murdered by her husband five years ago will receive $850,000 as part of a settlement with a security firm that failed to provide adequate protection for the victim. In October 1998, Jill Cahill, then 41, had spent six months semi-comatose in a Syracuse hospital recovering from wounds she obtained when her husband, James Cahill, attacked her with a baseball bat. Disguising himself as a janitor, Cahill's husband, now on death row, entered her hospital room and poisoned her with cyanide. Cahill's family sued Doyle Security Systems of Rochester, the hospital's security firm, for negligence, alleging the company failed to protect Cahill. The settlement came as the case was scheduled to go to trial in State Supreme Court.
