BROCKTON – A Brockton man has been indicted on charges that he stabbed his mother to death at their family home, Plymouth County District Attorney Timothy J. Cruz has announced.

A Plymouth County Grand Jury today returned indictments against Frantz Polynice (DOB: 02/02/98) of Brockton, charging him with one count of Murder and two counts of Assault and Battery with a Deadly Weapon.

At approximately 12:30 pm on November 30, 2016, Brockton Police received a 911 call from a neighbor. The neighbor, who resided at 34 Merritt Avenue, called on behalf of a woman who had appeared at her door hysterical and only spoke Haitian Creole. The woman motioned
for the neighbor to follow her back to 34 Merritt Avenue where they entered a side door to the kitchen. As they entered the kitchen, Polynice was seen coming out of the living room and approaching the women wielding a knife. The women ran from the house and stood in the street.
Polynice exited the house and sat on the porch steps until emergency personnel arrived.

Upon arrival, Brockton Police and emergency medical personnel found 44-year-old Mania Menieda lying on the living room floor with multiple stab wounds. She was transported to Signature Hospital in Brockton where she was pronounced dead at 1:36 pm. Menieda was the
mother of Polynice.

Investigators interviewed family members who reported that Polynice had refused to eat or drink in the days before the murder. Investigators also learned that Meneida had attempted to get him help and return him to live with an aunt in Haiti but he refused. Meneida was attempting to get Polynice to eat a meal that day when he turned on his mother with the knife. An autopsy revealed that Polynice stabbed Meneida numerous times about the head and face and upper torso.

Polynice, who is currently being held without bail, will be summonsed to Brockton Superior Court for arraignment.

Assistant District Attorney Richard Linehan is prosecuting the case, which was investigated by State Police Detectives assigned to the Plymouth County District Attorney’s Office and Brockton Police.
