Who or What Killed Hugo Ramirez?

Police are trying to confirm what killed a man who was found near Belmopan last night. Close to 10, police were called to that stretch of road near the Agriculture and Trade Show Grounds. They found 33 year old Hugo Lionel Ramirez with massive head and body injuries. But while police suspect he was knocked down, they aren't sure. And because he was unaccompanied, they can't say. So now, they are asking anyone with information on his last whereabouts to please call the police.
