Man Found Guilty Of 2018 Nassau Murder

HEMPSTEAD, NY — A Hempstead man was found guilty on Friday of murdering another man in broad daylight in a 2018 shooting.

Jamik Cannon, 28, was convicted by a jury of second-degree murder, first-degree assault and two counts of second-degree criminal possession of a weapon. He was remanded into custody and is due back in court on July 15 for sentencing, and faces 50 years to life in prison.

“The victim stood outside in the late-morning, talking to a friend, unaware of the defendants’ impending attack that would take his life,” said Nassau County District Attorney Madeline Singas. “We hope that this conviction provides some measure of closure for the family and friends of Demetrius Winfield who continue to mourn after this senseless act of violence.”

According to Singas, at 10:54 a.m. on Oct. 19, 2018, Demetrius Winfield was on a break from his job ata home on Wellesley Street in Hempstead and was talking to a friend. The two were shot by Cannon and his accomplice Brian Marshall-Gibson. The two fired at least 15 shots in 14 seconds.

Winfield was shot in the face, chest and groin and was pronounced dead at Winthrop Hospital. The second victim, who authorities have not named, was also shot, but survived, and is recovering from his injuries.

Cannon and Winfield knew each other and had gotten into an argument three days prior at a gas station.

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

Marshall-Gibson pleaded guilty on April 29, 2020 to second-degree murder and second-degree criminal possession of a weapon. He was sentenced on Aug. 24, 2020 to 20 years to life in prison.
