From an article:
A neighbor speaking on condition of anonymity told WAVY.com how the scene unfolded, "The father of the baby, the mother and the other man everybody was arguing. The father went back out to his car and got a gun and he shot up. He's downstairs. He shot up. He didn't mean to shoot his baby, but he just shot up and shot the baby."
The neighbor said she was in a hallway at the apartment complex when the shooting happened.
