Kanasho Johns, 29, and Kevin Deon Johnson, 26, were convicted in October for the 2015 murder of Tavin Price. Johns, who was also convicted of felony possession of a firearm, received an additional three years for that charge.
Last May, Price and his mother, Jennifer Rivers, were at a car wash near the corner of Florence Avenue and Crenshaw Boulevard.
Price had gone to a nearby store, where he was approached by a man who asked Price to remove his shoes. Price walked back to his mother at the car wash to tell her what happened when the man followed him back to the car and opened fire.
Price was shot four times in the back and chest by Johns, and he later died at the hospital, prosecutors said.
Prosecutors say Johns and Johnson were two neighborhood Crips members, and they targeted Price because of what he was wearing.
Rivers described her son as having a mental capacity of a 12-year-old, saying he was never affiliated with a gang in his life. Price was also described as standing under 5 feet tall and weighing less than 90 pounds.
A third man, 31-year-old Dwight Kevin Smith, pleaded guilty on one count of voluntary manslaughter in August. He faces 12 years in state prison.
