In February 2022, District Attorney Tierney formed the Gilgo Beach Homicide Task Force with the Suffolk County Police Department, New York State Police, Suffolk County Sheriff’s Office, Federal Bureau of Investigation, and other law enforcement partners, to reinvigorate the investigation into the series of murders that occurred between 1993 and 2010 in Suffolk County. In March 2022, the Task Force developed a suspect which they investigated over the course of the next 16 months, culminating in the indictment and arrest of Rex A. Heuermann in July 2023 for three of the murders. In January 2024, Heuermann was charged by the grand jury with a fourth murder. In June 2024, Heuermann was charged again by the grand jury with two more murders. In December 2024, Heuermann was charged again by the grand jury with an additional murder, bringing the total number of homicides charged to seven. District Attorney Tierney has been deeply involved in this case from it’s inception and will conduct the trial in this case along with a team of other experienced prosecutors.
