The man who stands accused of being the notorious Long Island Serial Killer is dealing with unspecified health issues, Us Weekly can confirm. Rex Heuermann was a no-show Tuesday, March 17, for a hearing in his ongoing criminal case on Long Island. The hearing proceeded as planned, and afterwards, Heuermann's attorney, Michael Brown, told reporters that his client has been using crutches for little over a month. Heuermann, 59, is dealing with some health issues, Brown said.
