Rockland County District Attorney Thomas E. Walsh II announced today the sentencing of Constantinos Doonan, a/k/a “Dino” (DOB 7/17/92) of New City, New York on a charge of Murder in the Second Degree (class “A” Felony), and Jo-Ann Haughey (DOB 1/15/96) of New City, New York on a charge of Manslaughter in the First Degree (Class “B” Felony), in the killing of Constantinos Mastakouris. Constantinos Doonan, a/k/a “Dino” is the grandson of the deceased Constantinos Mastakouris.
In the County of Rockland, on or about and between January 29 –30, 2023, acting individually and in concert with each other, the defendants brutally caused the death of Constantinos Mastakouirs of 45 Ruth Drive, New City, New York.
Mr. Mastakouris was strangled and choked to death; after he was killed, the defendants wrapped his body in a tablecloth, kiddie pool, and shower curtain and then placed the body in a crawl space in the basement of 45 Ruth Drive, New City, New York. After they placed the body in the crawl space, the defendants stole Mr. Mastakouris’ belongings, including but not limited to his car, jewelry, and credit card.
District Attorney Tom Walsh said, “Today, the defendants in this case were held responsible for their heinous crimes that resulted in the senseless murder of an 85-year-old man, who was the grandfather of one of the defendants. The killing of one’s grandfather is evil and an unimaginable act. The actions of the defendants have left their family completely shattered by this horrific act. The defendants are being held fully accountable for their crimes and will serve lengthy prison terms. I commend the investigation by the Clarkstown Police Department and prosecution by Deputy Chief Assistant District Attorney Dominic Crispino and Supervising Assistant District Attorney Sharleen Bailon.”
Doonan and Haughey were sentenced on December 3, 2024. Doonan was sentenced to twenty (20) years to life in state prison on the second-degree murder conviction. Haughey was sentenced to fifteen (15) years in prison on the manslaughter in the first-degree conviction.
