An East Flatbush-based gang member has been sentenced to 15 years to life in prison following his conviction for the murder of a rival gang member in 2017.

The defendant, 22-year-old Gymanni Carrington, was sentenced to 15 years to life by Supreme Justice Dineen Riviezzo. Carrington also has a concurrent term of 12 to 24 years in prison for another crime. His sentence follows guilty pleas from 17 co-defendants who were also indicted in June 2018 after a long investigation into the gang’s violent activities.

Brooklyn District Attorney Eric Gonzalez announced the sentencing on Monday and referred to it as the final act in a successful takedown of the Martense Beverly Bosses street gang.

“Today’s sentencing is the final disposition of a takedown of a gang that operated in Brooklyn with reckless disregard for life while hunting and shooting rivals,” Gonzalez said. “This defendant will now spend many years in prison for his callous actions that took the life of a young man and endangered many others.”

Carrington, a resident of Crown Heights, was convicted on June 26, of killing Donovan Frazier following a bench trial. His charges included second-degree murder, second-degree conspiracy, second-degree criminal possession of a weapon, and fourth-degree conspiracy.

On the morning of Sept. 16, 2017, Carrington shot Frazier, then 20, while Frazier was leaving Franklin’s Finest Deli on Franklin Avenue in Crown Heights. The fatal attack was gang-related, as Frazier was a member of the rival Lincoln Fam gang. Surveillance video captured Carrington firing six shots into the deli from a .40 caliber handgun, one of which caused Frazier’s death.

Evidence from the trial also showed that Carrington boasted about the murder, both on recorded calls from the NYC Department of Corrections and on social media. He even sent emails admitting the crime to his mother shortly after the shooting.

The Martense Beverly Bosses and their members, including Carrington, were charged in 2018 with multiple crimes connected to eight separate shootings, two of which were fatal. Evidence from the trial revealed that the gang actively engaged in conversations about shootings and other acts of violence against their rivals between June 1, 2016, and June 14, 2018.

Carrington’s co-defendants previously pleaded guilty to a variety of charges, including conspiracy, manslaughter, and possession of a weapon. Their sentences ranged from one to three years, with some sentenced to up to 13 years in prison. One defendant received probation.
