1600: KMBC-TV is reporting the name of the deceased- 22 year-old Kasandra Perkins-

KMBC-TV correspondent Diane Cho is reporting that Perkins and Belcher got into an argument because Perkins apparently got home late from a concert Friday night in Kansas City.

SUNDAY UPDATE: Apparently, Perkins and Whitney Charles- the wife of Chiefs RB Jamaal Charles were cousins... here's more on Perkins from KSHB-TV
((HT: NBCActionNews.com))
Isaac Rauch, over at Deadspin, has published a piece involving an individual claiming to be close to Belcher.

This source is telling Rauch that Belcher's relationship with Perkins was one of two people who were "young and immature." The fight over the concert Perkins attended was only part of the dynamic and not the last straw. Belcher, allegedly, was balancing medication, alcohol, and occasional short-term memory loss from his playing time.

The November 18th game the Chiefs played against Cincinnati as a game that Belcher took direct contact to the head on more than one occasion- according to Rauch's source. Coaches held Belcher out of most of the Broncos game the following weekend since he was more of a run-stopper playing against a passing offense.

But, now we may have more of an idea on the "why." And if it is accurate, then the story compounded is even more sad.
