Read article today, DM's father died of a gunshot to the eye.... End result, deemed suicide. Police have said, they are looking into his death.... I hear of gun suicide deaths... Usually its side of head or mouth... But eye? Also police are very confident, Bosma had NO involvement with any of these people.
I'm thinking DM was involved in something criminally organized with people above him. To show him that they, the people above him, were serious, they killed his father. Maybe in front of DM, who knows. But I think the murder of his father was to make a point.
