Mariners outfielder Greg Halman may have been stabbed to death because of an argument about loud music. Police spokeswoman Patricia Wessels says that loud music "appears to be the reason the victim walked downstairs," but police are still trying to piece together what happened after that. Authorities are still interviewing the brother of Halman as a suspect in the death of the 24-year-old Dutch baseball player, who was killed in the early hours of Monday morning at an apartment in Rotterdam.
