Koker, 17, and Naceir Mayes, 15, are facing adult felony charges of 1st degree attempted intentional homicide for allegedly shooting a 17-year-old boy in the chest Jan. 21 after he got off a bus at the transit center on State Street.
Mayes will also have a combination status conference/arraignment; his next court date is Feb. 16.
Koker is also charged with carrying a concealed weapon, and Mayes is charged with possession of a firearm by a felon and possession of marijuana.
According to their criminal complaints, Mayes admitted to police that he and Koker are members of a gang, and they had problems with the victim, who is a member of a rival gang on the other side of town. The defendants were both armed when they reportedly went to the bus station to confront the boy.
Police say during a brief verbal exchange, both Mayes and Koker fired, and it is unclear who fired the shot that hit the victim in the chest. The second shot grazed the arm of the boy’s sweatshirt.
Koker and Mayes remain in the Racine County Jail on $500,000 cash bonds.
