The owner of the Matrix Center in Danbury died this weekend in a car crash on Long Island.  Port Jefferson Police say 48-year old Glen Nelson hit a telephone pole Sunday afternoon with his Lamborghini.  It was not immediately clear if speed was a factor in the crash.  Nelson founded the Matrix Group in 1993.  He purchased the old Union Carbide building in Danbury in 2009.  Sunday's accident happened two days before Nelson's 49th birthday.
