He then attests that Birdman should be partially held responsible for the incident and is a party to the crime. In a recent interview with Angie Martinez, Birdman maintained that he had no involvement in the shooting, and that Lil Wayne is his son forever. Birdman and Young Thug were previously named in an indictment that connected them to the shooting, though they haven't been brought in on any charges at this time. We will continue to update this story when more details are made available.
