On or about and between January 29, 2023, and January 30, 2023, Doonan and Haughey, acting individually and in concert with each other, killed Constantinos Mastakouris at 45 Ruth Drive in New City, New York.

After Doonan and Haughey killed Mr. Mastakouris, they hid his body in a crawl space located in the residence, in close proximity of where they slept with their children. On or about and between January 29, 2023, and March 19, 2023, Doonan and Haughey stole and possessed property belonging to Mr. Mastakouris, which they did not have permission or authority to use.

District Attorney Thomas E. Walsh II said, “I would like to commend the investigation by the Clarkstown Police Detective Bureau on this case. 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. “  

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

On December 7, 2023, Doonan and Haughey were arraigned in front of the Honorable Kevin F. Russo and were remanded without bail to the Rockland County Jail. The defendants face a maximum of 25 years to life in state prison if convicted. 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.
