The parents of one of the victims are upset about the status of Michael Hayes, who was acquitted by reason of insanity in the 1988 shooting that killed Thomas Nicholson and three others. Doris and Nick Nicholson are using a two million dollar judgment they won against Hayes in 1990 to find out information about him. Hayes has lived at the Dorothea Dix mental hospital in Raleigh. His attorney, Karl Knudsen, says the Nicholsons are using the litigation to exact whatever retribution is available to them. He says his client has a right to privacy.
