According to multiple overseas reports, and the Associated Press, an argument over the merits of Mike Tyson and Klitschko brothers caused a heated argument that ended in murder. A Russian college teacher stabbed his friend to death, investigators told the AP. Nikolai Makeyev, a teacher in the Siberian city of Tyumen, was having drinks with two other men in his apartment when the argument broke out.

"Makeyev said that Tyson would come out as winner, but his guest accused him of a lack of patriotism. The host did not like that and he fatally stabbed the victim several times in the back," the investigation report said.

The other guest, Makeyev's friend, managed to flee to his own apartment though he also had stab wounds, and his wife called the police.
