Gilgo Beach serial killer suspect Rex Heuermann has been charged with two additional murders.
Heuermann, of Long Island, was indicted on Thursday for the murders of 20-year-old Jessica Taylor in 2003 and 28-year-old Sandra Costilla in 1993.
The 60 year-old is now accused of killing six women in total.
Heuermann made an appearance at a Long Island court this morning as the new charges can be put to him.
He has pleaded not guilty to the murders of four other women, who were sex workers.

It comes a week after police searched his dilapidated home in Massapequa Park, Long Island.
That sparked speculation they’d been able to pin other murders to Heuermann.
The headless and handless body of Taylor, 20, was discovered in the woods of Manorville, New York, in 2003. The rest of her remains were discovered in 2011 over 40 miles away near Gilgo Beach on Long Island.
Costilla, who lived in Queens, was tied to the Gilgo Beach investigation after an April search the property were her remains were found.
She was strangled and was possibly raped, police said after her remains were found. Her body was found naked with her hands tied behind her back.
Unlike the other victims in the case, Costilla has never been described as a sex worker by law enforcement.
Detectives were seen scouring woodland close to where body parts belonging to the two were found.

Search teams with K9s were seen sweeping the wooded area in Manorville over three days.
Last month, detectives also went back to search the alleged serial killer’s Long Island home.
Officers had recovered a cache of weapons during an initial search following his arrest last summer.
Heuermann was arrested in July and initially charged with killing Melissa Barthelemy, 24, Megan Waterman, 22, and Amber Lynn Costello 27.

In February, he was also charged with the murder of Maureen Brainard-Barnes, 25.
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, an architect, has pleaded not guilty to all counts and currently remains in jail awaiting trial. A date for trial has not yet been set.
The Gilgo 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.
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

All of the victims worked as escorts who advertised themselves on Craigslist.
Heuermann was linked to the killings by DNA on the burlap used to transport the bodied which was compared to samples taken from a pizza crust and napkin that were discarded outside his Manhattan architectural firm, police said.
The samples boasted a 99.96 percent match, according to law enforcement officials.
Cops said they were alerted to Heuermann as a potential suspect after a witness linked Heuermann’s Chevrolet Avalanche to Costello’s murder.
The car was then tied to Heuermann’s cellphone records, which allegedly linked him to locations related to the murders.

The indictment stated that Heuermann had used different burner phones to contact each of his victims.
Cops also accused Heuermann of using Barthelemy’s phone to make taunting phone calls to her family from the comfort of his office.
Her sister Melissa told how she was bombarded with threatening phone calls from the killer who boasted of the killing and was keeping tabs on her movements.
Vess Mitev, a lawyer for Heuermann’s two adult children, said the family was closely monitoring the developments.
‘The hearing is yet another mile marker in this macabre saga, where they continue to be unfortunate bystanders,’ he said.
