The 7-year-old boy who fatally shot his 3-year-old sister in Southeast D.C. late last month got a gun from a 17-year-old boy in the home, documents filed by prosecutors say.
The 17-year-old has been charged as a juvenile with first-degree child cruelty and handgun offenses.
Court documents show the 17-year-old gave the 7-year-old boy a nylon bag with the 9mm handgun inside, The Washington Post reported.
According to the documents, the boy told police he took the gun out and started playing with it in a bedroom. The boy told police he accidentally pulled the trigger.
Little Dalis Cox died after she was accidentally shot about 8 p.m. Wednesday, July 29. The shooting occurred in an apartment on the second-floor of an apartment on the 600 block of 46th Place SE in Benning Ridge.
D.C. Police Chief Cathy Lanier previously said detectives were investigating whether a teenager had brought the gun into the home.
