Nineteen-year-old Lameco Turner, 19-year-old Ray Grace and 16-year-old Tarris Turner are charged with capital murder.
Officials say Lameco was the one who pulled the trigger.
A Crimestoppers tip led police to one of the suspects and the murder weapon.
Officials then arrested the other two suspects and took all three in for questioning.
The suspects confessed to shooting Prahkash Shah.
Two of the teenagers have also been charged with the April 12 robbery of the Sandhar Grocery Store located on Third Avenue.
