South Floral Park Man Pleads Guilty to Murder and Attempted Murder Charges for October 2018 Slaying

Updated transparent seal

MINEOLA, N.Y. – Nassau County District Attorney Madeline Singas announced that a South Floral Park man pleaded guilty on Wednesday for his role in a broad daylight murder and attempted murder that occurred in Hempstead in October 2018.

Brian Marshall-Gibson, 25, pleaded guilty before Judge Robert Schwartz to charges of Murder in the Second Degree (an A-I felony), Attempted Murder in the Second Degree (a B violent felony) and Criminal Possession of a Weapon in the Second Degree (a C violent felony). The case was adjourned for sentencing on June 30. The NCDA is recommending a sentence of 22 years to life in prison.

“The two male victims were talking outside a house on Wellesley Street just before 11 a.m. when the defendants ambushed them, leaving one man dead and another shot in the leg,” DA Singas said. “This senseless act of violence – allegedly to settle a fight that occurred a few days earlier at a gas station – happened in close proximity to a school and in a residential neighborhood. We hope this plea helps the family and friends of Demetrius Winfield in the grieving process as they continue to mourn his tragic loss.”

DA Singas said that on October 19, 2018, at approximately 10:54 a.m., victim Demetrius Winfield, was with a friend, a local cab driver on break, in front of a home on Wellesley Street in Hempstead. Winfield and his friend were then allegedly shot by Cannon and Marshall-Gibson.

Winfield was shot in the face, chest and groin and was pronounced dead shortly afterward at Winthrop Hospital. The second man was shot in the leg and is recovering.

Cannon and Winfield were known to each other and had gotten into a disagreement several days earlier at a gas station.

Cannon and Marshall-Gibson were arrested by members of the Nassau County Police Department on December 11, 2018.

The case against Cannon is pending.

Senior Assistant District Attorney Michelle Lewisohn of DA Singas’ Major Offense Bureau and Assistant District Attorney Paula Cajdler of the County Court Trial Bureau are prosecuting this case. Marshall-Gibson is represented by Dana Grossblatt, Esq. and Cannon is represented by Dennis Lemke, Esq.

The charges are merely accusations and the defendants are presumed innocent until and unless found guilty.
