MIAMI — As kids, Jamarco Stafford and James Adams shot hoops on the worn basketball courts of an Overtown housing project. Lifelong friends, they attended the same Head Start program, and helped win football games for the Overtown Rattlers — Stafford sporting number 88, Adams wearing 50. Some nights, Adams slept at Stafford's house. Now the teens, both 17, spend their nights in detention cells, facing murder charges for killing each other's brother.
