Naugatuck Man Sentenced To 90 Years In Waterbury Murder Case: DCJ

NAUGATUCK, CT — A Naugatuck man accused of murdering a Waterbury woman last year has been sentenced to 90 years in prison, according to the Connecticut Division of Criminal Justice.

In a news release, Waterbury State's Attorney Maureen Platt said Franklin Robinson, 40, of Naugatuck, was sentenced Wednesday on charges related to the 2022 murder of Mabel Martinez Antongiorgi, 56, in Waterbury.

According to evidence introduced at trial, Robinson and two other men were on Walnut Street in Waterbury on April 9, 2022, when multiple gunshots were fired at a vehicle and missed their intended target.

As a result, Antongiorgi was fatally struck by the gunfire while ironing in her home, according to Platt. A second person was also wounded as a result of the shooting but later recovered.

According to Platt, evidence showed Robinson planned the shooting and was found criminally liable for murder, both as an accessory and under the Pinkerton theory of liability, which means a person can be held responsible for crimes committed by their co-conspirators.

On July 20, a jury found Robinson guilty of murder, attempted murder, first-degree assault, conspiracy to commit murder and murder under Pinkerton theory of liability.

According to the Darien Times, Antongiorgi was the mother of Yarimar Mercado Martinez, who was on the Puerto Rican rifle shooting teams at both the 2016 and 2020 Olympics.
