A man named Dayvonta Mackey, who was part of a gang called the 1800 Boys, has been found guilty of killing Marquis Carter in a dispute over territory in November 2022.
On April 29, a jury found 39-year-old Dayvonta Mackey guilty of manslaughter, using a gun in a crime, having a gun with a previous felony conviction, and carrying a handgun during Carter’s death on Wilkens Avenue on Nov. 3, 2022. The manslaughter charge was a lesser offense because Mackey was initially charged with murder and other weapons charges.
Mackey, defended by lawyers Benjamin Charlton and Amanda Savage, was sentenced to 10 years for manslaughter, 20 years for using a gun in a crime, and 15 years for having a gun with a previous felony conviction on May 15 by Baltimore City Circuit Court Judge Althea M. Handy. The charge of carrying a handgun was included in the other charges.
Mackey was one of nine gang members indicted, and his trial showed he planned to kill Carter. Videos showed him watching Carter, checking the area, and planning to escape with two other gang members before shooting Carter three times.
The prosecution said the shooting happened because of an argument over drug territory. However, Charlton said Carter had shot Mackey five years earlier and had threatened to kill him. The defense also said there was no proof that Mackey was part of the gang, even though he had a history of selling drugs.
