The Gilgo Four: Who are they?

Their bodies were found near Gilgo Beach in 2010 and 2011, but their murders started in the ’90s.

Amber, who was known for her quirky and generous nature, went missing in September 2010. Her flatmates had to step in to protect her from a dangerous client before her disappearance. On the night she vanished, she left without her phone or purse to meet a man who promised her a large sum for a 24-hour engagement. Her case was linked to the suspect years later, leading to a breakthrough in the investigation.

So, what was the impact of The Gilgo Four discovery?

The discovery of these four women’s bodies was crucial in shifting the investigation into high gear. It wasn’t just the number of victims, it was the fact that they were all sex workers. This suggested that the killer was targeting women in that specific line of work. As more bodies were found, authorities began to realise they were dealing with a serial killer, someone who was likely local to the area.

While the investigation had previously lacked urgency, especially due to the victims’ profession, the discovery of The Gilgo Four brought national attention and more resources to the case. Other bodies were discovered nearby, including Shannan Gilbert, whose 911 call is played at the beginning of Gone Girls.

In 2023, nearly 30 years after the first murder, architect Rex Heuermann was arrested. He was charged with the murders of seven women, including the Gilgo Four. The arrest followed years of investigation and a key tip from Amber’s flatmates, whose detailed description of a man who had visited her before her disappearance eventually led to Heuermann’s capture.
