John Bittrolff's house

Serial Killer House in Manorville, New York

This is the former home of murderer and suspected serial killer John Bittrolff.

It is situated at 167 Silas Carter Road in Manorville, New York.

Bittrolff's wife purchased the property in 1997 for $198,500. He lived here until 2014, when he was arrested for the murders of two sex workers named Rita Tangredi and Colleen McNamee.

He was convicted of the crimes in July 2017. Two months later, the District Attorney's Office prosecutor publicly named him as a potential suspect in the Long Island serial killer case. However, that changed on July 14th, 2023, when the police arrested Rex Heuermann in connection with the murders. Interestingly, Heuermann's cell phone history showed that he had actually searched Bittrolff's name on Google.

Bittrolff is also the prime suspect in the murder of Sandra Costilla, whose body was discovered near Old Fish Cove Road in Southampton in November 1993.

He was linked to the murders of Tangredi and McNamee after a swab from one of his brothers proved to be a familial DNA match with semen samples that were collected from the victims' bodies.

Both women had been beaten, raped, and similarly posed in wooded areas. Their left shoes and underwear were also missing from the crime scenes—a sign that he may have kept them as trophies.

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 talking 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, Bittrolff allegedly responded, "I f**king knew it. I f**cking knew it."

It was taken in August 2012, which was roughly two years before he was charged with the murders of Colleen McNamee (20) and Rita Tangredi (31).

If you have ever researched Bittrolff, then you will already know that there are almost no personal details about him on the Internet.

Despite this, we were able to piece together his background and childhood by using online records, criminal record searches, and personal accounts from people who knew him.

Bittrolff was born on July 1st, 1966, to John Frederick Bittrolff and Lynne F. Bittrolff (nee Norwick). He has two younger brothers named Timothy and Kevin.

His parents separated when he was just a child. Around the same time, his father's brother, Kenneth Bittrolff (Uncle Kenny), started living with his mother.

He grew up at 40 Shore Drive in Mastic Beach, New York, with his mother, Lynne, his uncle, Kenneth, and his two brothers.

One source said that his mother was domineering and often absent. However, she treated Bittrolff like "the golden child". In her eyes, he could do no wrong.

As a teenager, he randomly provoked fights, broke into people's homes, stole things, vandalized property, and picked on younger kids. On one occasion, he reportedly forced a kid to eat a black snake firework. On another occasion, he fired a tipless arrow at someone's leg.

One person described him as "fearless" and said that there were a number of times when he would just walk up to someone without saying a word and "start swinging."

Another neighbor said that he killed his family's pet cat.

These reports are backed up by remarks from Detective Sgt. Charles Leser of the Suffolk County Police Department. During a 2017 interview with The Daily Beast, Lesser stated that Bittrolff tortured animals as a youngster and that he was nicknamed Crazy Johnny B.

Bittrolff attended William Floyd High School. Although one "classmate reunion" website states that he graduated in 1984, this seems to be incorrect (this information was added by members of the public, one of whom misspelled his surname).

His photo is not present in the 1984 William Floyd High School yearbook. Furthermore, a source familiar with the matter told us that he was held back in 1984 and that he was actually expelled the following year after he drove a dirt bike through the school grounds and knocked over an assistant principal who attempted to stop him. Although "Crazy Johnny B" fled the scene on his bike, he was identified after an onlooker recognized him from an earlier incident.

Bittrolff has worked as a self-employed carpenter throughout most of his adult life. Judging by public records, he owned at least two contracting companies. These were called "Coastal Construction" and "My 2 Boyz Contracting", both of which were registered by his wife.

On March 22nd, 1987, he was arrested and charged with fourth-degree grand larceny. He pleaded guilty in July 1987 and was sentenced to 60 days in jail and five years' probation.

One person who lived in Bittrolff's old neighborhood remarked that he had a reputation for stealing: "If someone robbed your house, it was probably John."

On October 8th, 1990, he was charged with third-degree assault after he beat up someone with a baseball bat (he reportedly did this as a favor for someone else).

In February 1994, he pleaded guilty to the crime and received a one-year conditional discharge. This would have required him to stay out of trouble for a year. There may have also been other conditions attached.

In 1994, he also pleaded guilty to driving under the influence. However, it is unknown when the incident occurred.

He started dating Patricia Asero in the mid-1980s. By 1993, they were engaged and living together.

The couple got married in 1995. Patty gave birth to their first son in July 1996. Their youngest son was born circa 2001–2003.

His father, with whom he reportedly had a strained relationship, passed away in 1998.

Before moving to Manorville, he lived on Concord Road in Shirley and Orchard Neck Road in Center Moriches.

When he was arrested for the murders of McNamee and Tangredi, shocked neighbors described him as a "regular guy" who was helpful and pleasant. They also said that he liked to hunt deer.

Although his name did not appear on the deeds to 167 Silas Carter Road until 2003, this was most likely due to mortgage-related reasons. For example, there may have been issues with his criminal record, self-employment income, or tax records. Notably, one source told us that he may have filed for bankruptcy at some point during the mid-1990s.

Rita Tangredi and Colleen McNamee

On July 5th, 2017, Bittrolff was convicted of the murders of Rita Tangredi and Colleen McNamee.

The naked body of Tangredi was found in a wooded area in East Patchogue on November 2nd, 1993. The killer had bludgeoned the 31-year-old sex worker and strangled her to death.

Three months later, on January 30th, 1994, the remains of McNamee were discovered in a forested area near the Long Island Expressway in Shirley. Like Tangredi, the 20-year-old 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 apart. Furthermore, both victims were missing their underwear and left shoes.

For more than 20 years, their murders remained unsolved.

Then, in 2013, 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 Tangredi and McNamee.

Bittrolff became the prime suspect after Timothy's DNA match proved that he was closely related to the killer.

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 eventually discarded an item with his DNA on it.

However, Bittrolff immediately saw through this facade and realized that he was being followed by the police. At one point, he even pulled an evasive driving maneuver in an attempt to lose them.

When the lab tested items from the family's garbage, they found a sample that matched the DNA found on Tangredi and McNamee.

At that point, the police decided to pull him over and bring him in for questioning. During the interrogation, he drank from a cup that they offered him. This cup gave investigators a sample of his DNA, which confirmed the match.
