The women known as the 'Gilgo Four' were discovered close to Heuermann's Long Island home. However, other bodies - including those of sex workers - have been found in the area
The first victim, 24-year-old Melissa Barthelemy, was discovered by Suffolk County Police on December 11, 2010. The body of Megan Waterman, 22, from Maine, was found two days later

DNA found on the burlap wrapped around Waterman's body was a 99.96 percent match to samples from a discarded pizza crust and napkin in a garbage bin outside Heuermann's firm, police said
In February, he was also charged with the murder of Maureen Brainard-Barnes, 25.
The searches come after the father-of-two's home in Massapequa was raided following discovery of the bodies.
The women were found wrapped in burlap and buried along the remote stretch of Ocean Parkway on Long Island's South Shore over a decade ago.
Heuermann has pleaded not guilty to all counts and currently remains in jail awaiting trial.
The women's remains were discovered during the search for 23-year-old Shannan Gilbert, an escort from New Jersey who had vanished in May 2010 after making a frantic 911 call.
Her remains were found along the same stretch of coast in December 2011 - and it was her body that led police to the discovery of the 'Gilgo Four'.
No one has ever been charged in Gilbert's death and police said it may have been accidental - but her family believe she was murdered.
The women were among 11 found on the desolate stretch of coastline close to Heuermann's Long Island Home between 2010 and 2011.
All of the victims worked as escorts who advertised themselves on Craigslist.
