A grand jury has brought an indictment against two Louisiana police officers who fatally shot a six-year-old boy after opening fire into his father's car.

The officers -- 23-year-old Norris Greenhouse Jr. and 32-year-old Derrick Stafford -- were charged with second-degree murder and attempted second-degree murder in the Tuesday shooting that made Jeremy Mardis the youngest person to be killed by law enforcement this year.
