The details of the murder-suicide of Kansas City Chiefs linebacker Jovan Belcher are troubling, and more information continues to become available. Why did an undrafted free agent from the University of Maine who earned a starting spot at linebacker kill his girlfriend and then himself early this morning? According the KansasCity.com, the two argued after Belcher's girlfriend returned early this morning from a Trey Songz concert. The couple had been dating for a few years and had a young child together. What is even more troubling is that Belcher's mother, who was visiting from New York, witnessed the shooting of 22-year old Kasandra Perkins.

Belcher left the scene and drove to the Chiefs practice facility, where he was met by general manager Scott Pioli and head coach Romeo Crennel. Details of the encounter are still coming in, but apparently Belcher told the two how grateful he was for the opportunity to play for the Chiefs. According to the Kansas City Star, when police arrived, they heard a gunshot and found that Belcher had shot himself in the head. Chiefs owner Clark Hunt issued the following statement:

“The entire Chiefs family is deeply saddened by today’s events, and our collective hearts are heavy with sympathy, thoughts and prayers for the families and friends affected by this unthinkable tragedy. We sincerely appreciate the expressions of sympathy and support we have received from so many in the Kansas City and NFL communities, and ask for continued prayers for the loved ones of those impacted.

“We will continue to fully cooperate with the authorities and work to ensure that the appropriate counseling resources are available to all members of the organization.”

Tomorrow's Chiefs-Panthers game appears to be on as scheduled, but you have to wonder what physical and mental condition the Kansas City players will be in. What has been a disastrous 2012 season just became a tragic one for the Chiefs and their fans.
