Investigators learned that earlier that night Bostic and his brother had been at Excalibur, where they'd scuffled with a group that included NBA player Tony Allen, a native west-sider who had just signed a new two-year, $5 million contract with the Boston Celtics.
It wasn't the first time Allen had been in a fight with members of the New Breeds. In 2005, he and several friends from the old neighborhood got into a confrontation at the White Palace Grill in the South Loop that ended with one man shot and another suffering a fractured eye socket.
Allen was eventually acquitted of aggravated battery.
Bostic and his brother weren't involved in the 2005 fight, but friends of theirs were, including two men who sued Allen for damages in civil court. "There was some notoriety amongst his crew," Commander Joe Gorman, the former head of the Chicago Police Department's gang investigations section, recalled of Bostic. "Him and Tony Allen, there were some confrontations amongst those groups."
