Defendant and co-conspirator shot and killed man in broad daylight

MINEOLA, N. Y. – Acting District Attorney Joyce A. Smith announced today that a Hempstead man was sentenced to 37 years to life in prison for the 2018 murder of a 30-year old man in Hempstead. 

Jamik Cannon, 28, of Hempstead, was convicted by a jury on May 14, 2021, of murder in the second degree (an A-I felony), assault in the first degree (a B felony), and two counts of criminal possession of a weapon in the second degree (a C violent felony). Cannon was sentenced before Judge Robert Schwartz to 37 years to life in prison. 

“This defendant and his accomplice turned a residential street in Hempstead into a killing field at 11 o’clock on a Friday morning,” said Acting DA Smith. “Fifteen gunshots over a petty argument took Demetrius Winfield’s life, nearly killed his friend, and terrorized the Hempstead community. We will continue to vigorously prosecute gun violence and its aftermath to the fullest extent of the law.”     

Acting DA Smith said that on October 19, 2018, at approximately 10:54 a.m., victim Demetrius Winfield was exiting his vehicle, on break from his job, in front of a home on Wellesley Street in Hempstead. Winfield and a friend were then shot by Cannon and his co-conspirator Brian Marshall-Gibson. Cannon and Marshall-Gibson fired at least 15 shots in 14 seconds.             

Winfield was shot in the face, chest and groin and was pronounced dead shortly afterward at Winthrop Hospital. The second man was also shot and continues to recover from his injuries.

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

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

Marshall-Gibson pleaded guilty on April 29, 2020 to charges of murder in the second degree, attempted murder in the second degree, and criminal possession of a weapon in the second degree. He was sentenced on August 24, 2020 to a combined 20 years to life in prison and five years’ post-release supervision.

Senior Litigation Counsel Michelle Lewisohn of the Homicide Bureau and Senior Assistant District Attorney Paula Cajdler of the County Court Trial Bureau prosecuted the Cannon and Marshall-Gibson cases. Cannon is represented by Dennis Lemke, Esq.
