The Nassau County Police investigated the hunt for '' The Honeymoon Killers '' Raymond Fernandez and Martha Beck in the late 1940s , the Weinberger kidnapping of 1956 ( on which the 2002 Robert De Niro film '' City by the Sea '' was very loosely based ) , the crash of Avianca Flight 52 in Cove Neck in 1990 , the Joey Buttafuoco/Amy Fisher imbroglio , and the shootings committed aboard a Long Island Rail Road commuter train by Colin Ferguson in 1993 . Among the NCPD 's few large-scale , high-profile security events have been the 1998 Goodwill Games , which took place largely in Nassau County , and the third 2008 presidential debate , which took place at Hofstra University in Hempstead . Nassau officers also participated in the recovery effort at the World Trade Center site in September 2001
