The suspect is an architect and has lived much of his life in
Massapequa Park on
Long Island. According to an interview he did with a YouTuber, he has worked in
Manhattan since 1987.
[101] Authorities began to seriously consider him as a suspect in March 2022 after discovering that a
Chevrolet Avalanche registered in his name had been linked to one of the killings by a witness. Further investigation of his cellphone records indicated that he had been in contact with three of the four victims. Through June 2023, an email account linked to the suspect had conducted online searches of the investigation's progress. Court records also indicated that he had searched the internet for "sadistic materials, child pornography, [and] images of the victims and their relatives."
[101][102] Hair believed to be from the suspect's wife, who was out of state during the murders, was found on or near the victims and was matched using DNA testing. DNA taken from a pizza box discarded by the suspect was also used in his identification.
