New City Couple Accused Of Murdering His Grandfather

NEW CITY, NY — Constantinos Doonan, 31, and Jo-Ann Haughey, 26, have been arraigned on the felony charge of second-degree murder and other charges over the death of Doonan's grandfather, Rockland County District Attorney Thomas E. Walsh II and Clarkstown Police Chief Jeffrey Wanamaker announced Thursday.

Prosecutors allege that Doonan and Haughey killed Constantinos Mastakouris at 45 Ruth Drive in New City sometime between Jan. 29-30, 2023.

Mastakouris, Doonan's grandfather, was the owner of the house, and lived there with, amongst other family members, Doonan and Haughey and their two young children.

After Doonan and Haughey killed Mastakouris, they hid his body in a crawl space in the house, near where they slept with their children, prosecutors said.

Between Jan. 29 and March 19, Doonan and Haughey stole and possessed property belonging to Mastakouris.

Doonan and Haughey were charged with:

• Murder in the Second Degree (a class “A” violent felony)
• Burglary in the Second Degree (a class “C” violent felony)
• Grand Larceny in the Third Degree (a class “D” felony)
• Grand Larceny in the Fourth Degree – 3 Counts (a class “E” felony)
• Criminal Possession of Stolen Property in the Third Degree (a class “D” felony)
• Criminal Possession of Stolen Property in the Fourth Degree – 3 counts (a class “E” felony)
• Criminal Possession of Stolen Property in the Fifth Degree (a class “A” misdemeanor)
• Concealment of a Human Corpse (a class “E” felony)
• Endangering the Welfare of a Child – 2 counts (a class “A” misdemeanor)

"As a result of the tireless and collaborative efforts of the Clarkstown Police Detective Bureau and the of the Rockland County District Attorney’s Office, these individuals who have been arrested will now face justice for the heinous murder of Mr. Mastakouris," Clarkstown Police Chief Jeffrey Wanamaker said in the announcement.

Doonan and Haughey were arraigned Thursday in front of the Honorable Kevin F. Russo and were remanded without bail to the Rockland County Jail. They each face a maximum of 25 years to life in state prison, if convicted.

"I would like to commend the investigation by the Clarkstown Police Detective Bureau on this case," Walsh said. "The alleged actions of the defendants show a clear disregard for human life. What makes this case very troubling is the grandfather and grandson relationship between the defendant and victim."

First Assistant District Attorney Dominic Crispino and Senior Assistant District Attorney Sharleen Bailon are prosecuting the case. It should be noted that a criminal complaint is merely an accusation and that a defendant is presumed innocent until proven guilty.
