SEATTLE -- Family and friends said goodbye to Seattle Mariner Greg Halman at the public memorial service Sunday in the Netherlands. Meanwhile, police say an argument over loud music may have led to Halman's death.
At Halman's memorial, some mourners wore red caps from the club where Greg and his younger brother Jason played baseball in the Netherlands.
Jason Halman, 22, remains behind bars for reportedly stabbing his brother. The Halman family reportedly sought help for Jason before the attack.
"They were afraid that perhaps Jason would do something to himself, not to his brother, because they were so close," said Fritz Huizinga, family friend. "His brother was his big hero and his great example for life. We will never understand what happened."
Mariners Vice President Bob Engle also attended Sunday's service. Halman's burial is scheduled for Tuesday.
Meanwhile, police say an argument about loud music could be the reason Halman was stabbed to death.
Police spokeswoman Patricia Wessels tells The Associated Press that loud music "appears to be the reason the victim walked downstairs," but police are still trying to piece together what happened after that.
Police say they were still interviewing Jason 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.
Halman hit .230 in 35 games and made starts at all three outfield positions for the Mariners in 2011 before being optioned to Triple-A Tacoma.
