The death of a man last weekend means charges against a Milwaukee man could be upgraded to murder. Dorian Ramsey is currently charged with aggravated battery, but the victim died Saturday. Witnesses say he punched the man in the face and stomped his head while he was on the ground during an incident February 18th. The victim died seven weeks later. His girlfriend had called police when she heard the two men shouting at each other outside her house. The man who died was never able to tell investigators his version of what happened.
