Quincy Man Convicted Of Brutal 2015 Marshfield Murder

QUINCY, MA — A Quincy man was sentenced to life in prison without the possibility of parole after he was found guilty of first-degree murder in the 2015 killing of a Marshfield man found with his arm severed. A Plymouth Superior Court jury took four hours of deliberation to return the verdict on Michael Moscaritolo in the murder of Robert McKenna in his Marshfield home.

Superior Court Judge C.J. Moriarty sentenced Moscaritolo, 37, to life without parole.

"Robert McKenna was terrorized and left to die that day in 2015 and Michael Moscaritolo was the ringleader who orchestrated the massacre," Plymouth County District Attorney Timothy Cruz said. "This has always been about getting justice for Rob. Through three trials and this re-trial, Rob's family spent day after day in the courtroom listening to excruciatingly painful details of their loved one's murder. I hope that with this verdict they finally find some peace and are comforted by their memories of Rob's positive attitude, adventurous spirit and the joy that he brought to their family."

Cruz and Marshfield Police Chief Phil Tavares announced the verdict Wednesday afternoon.

The body of McKenna, 45, was found in his Damon's Point Road on Sept. 16, 2015 with a severed right arm and severe wounds to his head. The DA's Office said clothing, footwear and gloves were found at the scene and DNA testing determined the McKenna's blood was on one of the items.

Police identified Moscaritolo, Mark O'Brien, 44, and James Ferguson, 44, as the three suspects in the robbery and murder. Moscaritolo was found guilty of aggravated burglary, five counts of larceny with a firearm and unarmed robbery in 2019, but that jury did not reach a verdict on the murder charge, and a mistrial was declared.

"This crime was complex with several defendants," Cruz said, "and I commend the excellent police work of investigators to close out this case and bring all those involved with this horrific murder to justice."

Moscaritolo was also convicted of aggravated burglary and unarmed robbery in the retrial.
