SUFFOLK COUNTY, New York (WABC) -- Shannan Gilbert's disappearance in 2010 sparked the discovery of 11 bodies on and near Gilgo Beach on Long Island. After more than a decade passed with no arrest, 59-year-old Rex Heuermann was arrested on July 13, 2023. He was charged with three counts of first-degree murder and three counts of second-degree murder in connection with the deaths. Heuermann has pleaded not guilty to all counts, and he was named as a prime suspect in a fourth murder investigation.
The four deaths investigators believe Heuermann is connected to are those of the "Gilgo Four." The "Gilgo Four" were all petite sex workers in their 20s who advertised on Craigslist. All of their bodies were found wrapped in burlap near Gilgo Beach within a mile of each other.
Thirteen years after Gilbert disappeared, the Gilgo Beach murders case has garnered national attention once again. But this case has roots as far back as 27 years ago.
The first human remains connected to the Gilgo Beach murders are found.

April 4, 2011
Police find three more victims in the area between Oak Beach and Gilgo Beach, bringing the total count of victims to eight. Investigators identify the victims as Jane Doe Number 6, a baby girl and an Asian man.
The baby was found wrapped in a blanket and between 18 and 24 months old when she died. Investigators say they are unsure if she was murdered. They believe the man was in his late teens or early 20s when he died. Although a cause of death was not revealed, police say he died a violent death. He was found wearing what investigators referred to as women's clothing.
April 11, 2011
For the first time, investigators expand their search into Nassau County, and a ninth and 10th victim are discovered. Their bodies were found on Ocean Parkway in Jones Beach, about five miles from where the "Gilgo Four" were found. Police say they have several people they consider as persons of interest, but no suspect has been named.
The ninth victim, Jane Doe Number 9, is discovered to be Fire Island Jane Doe, whose legs were found in 1996. Due to DNA testing, it is also believed that she was the mother of the unidentified baby found on Gilgo Beach. Fire Island Jane Doe/Jane Doe Number 9 is renamed "Peaches" because of a tattoo found on her body. Investigators say they believe mom and baby were killed at the same time.
May 9, 2011
Investigators say that the fifth and sixth bodies that were found were dismembered, unlike the "Gilgo Four." Only the head and hands of the women were found on Gilgo Beach. The rest of their bodies had been found 20 years earlier, 40 miles away, in Manorville.
One of the dismembered women, Jane Doe Number 5, is named as 20-year-old Jessica Taylor. Taylor disappeared in 2003. She was working as a sex worker in New York City. The other woman remains unidentified, but investigators believe their two cases are linked. The partial remains of Jane Doe Number 6 are connected to Manorville Jane Doe, whose torso was found in Manorville in 2000.
Investigators now say they believe they are looking for three, if not four, killers. One killer who they believe is responsible for the "Gilgo Four," one responsible for Jane Doe 5 and Jane Doe 6, and one or two separate killers responsible for the four other bodies found.
Investigators have found 10 bodies and identified five of them, but they are still searching for Gilbert.
November 29, 2011
Suffolk County Police say they believe all of the 10 victims found on and near Gilgo Beach may have been related to sex work, even though only five of the 10 were identified. They say it is possible that one killer is responsible for all of their deaths. Even though her disappearance sparked the investigation, investigators say they do not believe Gilbert's case is connected.
After a year and a half of searching, investigators find Shannan Gilbert.
