John Bittrolff's childhood home

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

It is situated at 40 Shore Drive in Mastic Beach, New York.

In 2017, Bittrolff was convicted of murdering two sex workers called Rita Tangredi and Colleen McNamee. He is also the prime suspect in the murder of Sandra Costilla.

Bittrolff grew up in this house with his mother, Lynne, his uncle, Kenneth, and his two brothers, Timothy and Kevin.

As a teenager, he randomly provoked fights, broke into people's houses, 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 John 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."

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 John tortured animals as a youngster and that he was nicknamed Crazy Johnny B.
