Deadly shooting mars funeral service for 10-year-old victim of gun violence

Two people were shot, one fatally, at the funeral service for a 10-year-old girl who was killed by a stray bullet in Maryland last month.
The shooting was the result of a dispute unrelated to the funeral and the victims were not directly connected to the funeral.
A suspect has been arrested in connection with the shooting at the Washington National Cemetery.
The funeral was for Arianna Davis, who was accidentally shot while in a car with her family on Mother's Day.
One victim, an adult male, was pronounced dead at the scene while an adult female suffered non-life-threatening injuries.
