An argument over the respective merits of United States' boxing legend Mike Tyson and Ukraine's Klitschko brothers ended with a Russian college teacher stabbing his friend to death, investigators said Friday.
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 regional investigating committee said in a statement.
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.
Alcohol abuse kills around 500,000 Russians each year.
