John Bittrolff's house.
Serial Killer House in Manorville, New York, United States.
This is the former home of murderer and suspected serial killer John Bittrolff. The house sits on Silas Carter Road in Manorville, New York.
Bittrolff and his wife purchased the property for $198,500 in 1997. He continued to live here until 2014, when he was charged with the murders of two sex workers called Rita Tangredi and Colleen McNamee.
In July of 2017, he was convicted of the crimes. Two months later, the District Attorney's office prosecutor officially named him as a suspect in the Long Island serial killer case.
In addition to the LISK case, Bittrolff is also the prime suspect in the murder of Sandra Costilla. In November of 1993, Costilla's body was discovered near Old Fish Cove Road in Southampton, New York.
Bittrolff became a suspect in the murders of Tangredi and McNamee after a swab from one of his brothers proved to be a familial DNA match with semen that was collected from the victims' bodies.
Both of the victims had been beaten, raped, and similarly posed in wooded areas. Their left shoes and underwear were missing from the crime scenes.
Although the authorities initially claimed that there was nothing linking him to the Gilgo Beach victims, their public stance changed after he was found guilty and sentenced to two consecutive 25-years-to-life sentences.
Following his arrest, he claimed that he didn't know the two women. However, he became noticeably unsettled when the police told him that they had found his DNA on their bodies. At that point, he stopped speaking and asked for a lawyer.
Hours after the interrogation had ended, Bittrolff reportedly asked Detective John McLeer how they had collected his DNA. When McLeer explained that his brother's DNA had been entered into the system and that they searched through his garbage, Bittrolff allegedly responded, "I f**cking knew it. I f**cking knew it."

On July 5th, 2017, John Bittrolff was convicted of the murders of Rita Tangredi and Colleen McNamee.
The nude body of 31-year-old sex worker Rita Tangredi was found in a wooded area in East Patchogue on November 2nd, 1993. The killer had bludgeoned Rita and strangled her to death.
Three months later, on January 30th, 1994, the naked remains of 20-year-old Colleen McNamee were discovered in a forested area near William Floyd Parkway in Shirley. Like Rita, she had been beaten and strangled to death.
Both of these women were sex workers who were killed in a similar fashion. Their bodies were found nude and "posed" in wooded areas that were less than 10 miles away from each other. Furthermore, Colleen and Rita were both missing their underwear and left shoes.
For more than 20 years, their murders remained unsolved.
However, in 2013, John Bittrolff's brother, Timothy, was arrested for an unrelated crime. As a result, he was forced to submit a DNA sample. Not long after, Timothy's sample proved to be a familial match with the DNA evidence that was collected from the bodies of Rita Tangredi and Colleen McNamee.
This DNA match proved that Timothy was closely related to the killer of Tangredi and McNamee. As a result, John Bittrolff quickly became the prime suspect in the murders.
At that stage, investigators started using a fake plumber's van to keep Bittrolff under surveillance. Their goal was to follow the carpenter until he discarded an item with his DNA on it.
However, Bittrolff immediately saw through this facade and realized that he was being tailed by the police. At one point, he even pulled an evasive driving maneuver in an attempt to lose them.
Detectives also noted that he had a lot of beer bottles. However, he never put any of these bottles into the household recycling bin. Furthermore, when the lab did test items from the family's garbage, they were only able to find samples belonging to his wife and two sons.
All of this suggested that Bittrolff had a basic knowledge of forensic science and that he knew why he was being tailed.
After failing to find a DNA sample in his garbage, the police eventually decided to pull him over and bring him in for questioning. During questioning, he drank from a cup that they offered him. This cup gave investigators a sample of his DNA, which proved to be a match with the evidence that had been found on both Tangredi and McNamee.

Is John Bittrolff the Long Island serial killer?
John Bittrolff is a strong suspect in the case.
In 2000, the Long Island serial killer dumped the torso of Valerie Mack in a wooded area near Halsey Manor Road in Manorville. Two and a half years later, he also left Jessica Taylor's torso on a pile of wood scraps off Halsey Manor Road.
The two dump sites were just half a mile away from each other.
Both of the women were sex workers whose dismembered remains were found in an area that is only 3-4 miles away from John Bittrolff's house on Silas Carter Road.
Furthermore, one of these dump sites was on an isolated access road that is off the beaten track. This suggests that the killer has an intimate knowledge of the Manorville area.
In 2011, the police uncovered Taylor and Mack's skulls on Ocean Parkway—close to where the killer dumped the Gilgo Four.
This discovery proved that the Long Island serial killer had been operating in both Gilgo Beach and Manorville.
Following Bittrolff's conviction for the murder of Rita Tangredi and Colleen McNamee, the Suffolk County District Attorney publicly announced that he was a prime suspect in the LISK case.
Bittrolff and the Long Island serial killer both targeted petite sex workers. The details of their crimes indicate that they both derived pleasure from torture.
In September of 2017, the mother of Melissa Barthelemy stated that her daughter "had a lot of calls to Manorville" on her phone.
Finally, his behavior while he was under surveillance suggests that he has a rudimentary knowledge of forensic science.
A lot of people remain unconvinced about Bittrolff's involvement in the Long Island serial killer murders. In their opinion, the M.O. doesn't match.
However, this argument is based on the common misconception that a killer's M.O. will never change.
Other cases have repeatedly shown us that a serial killer's modus operandi can evolve. In reality, a killer's M.O. can change so quickly and remarkably that law enforcement will sometimes struggle to connect their crimes.
For example, Ted Bundy started off by breaking into women's houses and attacking them while they were sleeping. In January of 1974, he brutally assaulted Karen Sparks. Not long after, he abducted college student Lynda Ann Healy from her house in the University District of Seattle.
Following these first two attacks, Bundy drastically changed his M.O. Instead of breaking and entering, he started approaching his victims in public places and luring them back to his car by using various ruses.
The murders of Rita Tangredi and Colleen McNamee took place in 1993 and 1994. This means that there was plenty of time for Bittrolff's M.O. to evolve.
For example, at some point, he may have decided that he needed to lower his risk of being caught by putting more effort into concealing his victims' identities.
This might explain why he started dismembering his victims and dumping their body parts in different locations.
