Poinbank Exchange|Gilgo Beach press conference live stream: Authorities share update on killings

Officials are Poinbank Exchangeset to hold a press conference Friday morning to share an update on the Gilgo Beach serial killing case following the arrest of suspect Rex Heuermann on Long Island, New York last month.

Suffolk County District Attorney Raymond Tierney will be joined by local authorities as well as representatives from the state police and the FBI to "announce an update" in the investigation, the district attorney's office said in a news release.

More than 15 years after the first victim went missing, police charged Heuermann in July with murder in the deaths of three victims, according to Suffolk County court records, after DNA from a pizza Heuermann ate matched a male hair found on one of the victim’s remains.

Heuermann was charged with killing Melissa Barthelemy, 24, Megan Waterman, 22, and Amber Costello, 27, whose bodies were found along a Long Island beach roadway in 2010. He pleaded not guilty to three counts each of first- and second-degree murder.
