Why It Matters
The sentencing of Rex Heuermann to life without parole brought some measure of closure to the families of eight women he murdered near Gilgo Beach, New York. But law enforcement officials say the stretch of Ocean Parkway holds more secrets — at least four other individuals found in the same general area are not connected to Heuermann, and some of those cases remain unsolved decades later.
What Happened
Heuermann, a 62-year-old architect, pleaded guilty on April 24 to the murders of eight women: Maureen Brainard-Barnes, Melissa Barthelemy, Megan Waterman, Amber Costello, Jessica Taylor, Valerie Mack, Sandra Costilla, and Karen Vergata. He was formally sentenced to life without the possibility of parole at a hearing this week.
Nassau County District Attorney Anne T. Donnelly made clear the case does not close the book on Gilgo Beach. “Gilgo Beach can be described as a dumping ground,” Donnelly said. “There are a number of bodies that are not connected to the Gilgo Beach killer.”
The Unsolved Cases
Shannan Gilbert disappeared in May 2010 after visiting a client in Oak Beach, Long Island. Her skeletonized remains were discovered in a nearby marsh in December 2011. The Suffolk County medical examiner listed her cause of death as “undetermined,” though independent forensic pathologist Michael Baden conducted his own examination and concluded the findings were consistent with homicidal strangulation.
Former police commissioner Rodney Harrison weighed in on the case in 2022, stating, “Based on the evidence, the facts, and the totality of circumstances, the prevailing opinion in Shannan’s death was not a murder.” The case has never been officially closed as a homicide.
“Peaches” and Tatiana Dykes represent one of the more tragic threads in the Gilgo Beach story. The dismembered torso of an unidentified woman was found on June 28, 1997, in a West Hempstead state park. She had a distinctive peach tattoo, earning her the investigative nickname “Peaches.” Additional remains attributed to her were later discovered along westbound Ocean Parkway in the Zachs Bay area.
In April 2011, the skeletal remains of a toddler were found off Ocean Parkway at Gilgo Beach. Investigators eventually determined the child was the biological daughter of “Peaches.” The two cases were connected — a mother and her two-year-old daughter, their identities unknown for years.
A breakthrough came in April 2025, when the mother was identified as Tanya Jackson, 26, a U.S. Army veteran who had served from 1993 to 1995 and was originally from Mobile, Alabama. At the time of her death, she and her daughter had been living in Brooklyn, estranged from family. The toddler was identified as Tatiana Dykes, age two. Andrew Dykes, 66 — identified as Tatiana’s father — was arrested in December 2025.
Investigators also recovered the remains of an unidentified Asian individual in 2011. That person has still not been identified.
By the Numbers
- 8 — women Heuermann admitted to killing, earning him a life sentence
- 4+ — additional people found along Ocean Parkway not linked to Heuermann
- 1997 — year the “Peaches” torso was first discovered
- 28 years — approximate time between the discovery of Tanya Jackson’s remains and her identification in 2025
- 1 — additional unidentified victim (the Asian individual found in 2011) still without a name
Zoom Out
The Gilgo Beach investigation has drawn national attention as one of the most complex serial crime cases in recent U.S. history, involving multiple law enforcement agencies, competing autopsies, and victims whose cases span nearly three decades. Violent crime investigations involving unidentified victims have challenged law enforcement agencies nationwide, often requiring years of forensic work before families receive answers.
The identification of Tanya Jackson and Tatiana Dykes demonstrated how modern DNA techniques and renewed investigative focus can crack cold cases that once seemed permanent mysteries — but the work along Ocean Parkway is clearly not finished.
What’s Next
With Heuermann now sentenced, investigative attention is expected to shift more fully toward the remaining unresolved cases. The identity of the Asian individual found in 2011 remains an open question, and the full circumstances surrounding Shannan Gilbert’s death continue to be disputed. Prosecutors have signaled that the area’s history as a disposal site means additional investigative work is likely ahead.
