In September 1992, Ferguson was awarded $26,250 for his workers' compensation claim against Ademco Security Group. In April 1993, he insisted that he was still in pain and demanded that the case be reopened so that he could get more money for medical treatment. In the following weeks, Ferguson visited a Manhattan law firm for a consultation, and attorney Lauren Abramson said that she immediately felt uncomfortable and threatened by him. She asked a law clerk to sit in on the meeting because she did not want to be alone with him, which she had never done before. Ferguson was neatly dressed during the consultation, but he acted strangely and identified himself by a false name before providing his real name. Months later, he made threatening calls to members of the firm, claiming that they were discriminating against him. In one of the calls, he made reference to a massacre which occurred in California. The calls prompted the lawyers to start locking their inner office doors out of fear. Ferguson tried to have his workers' compensation claim reopened by the New York State Workers' Compensation Board, which reexamined the case due to his persistence, but it was ultimately rejected. The board placed him on a list of potentially dangerous people whom security guards were to watch for.
