WAUKEGAN, Ill. (AP) -- A judge in northern Illinois has sentenced a Tennessee man to 30 years in prison for killing another man over a $500 bet.

Judge George Bridges handed down the sentence Tuesday for 71-year-old Robert Bostic of Kingston, Tenn.

Bostic was convicted in September of killing 31-year-old Carlton Richmond in 1982. The shooting happened in a garage in Round Lake Beach that was used as a clubhouse by a motorcycle club.

Prosecutors in Lake County say Bostic downed a fifth of whiskey in one swig to win a $500 bet with Richmond and became angry when the other man wouldn't pay up.

Richmond's killing went unsolved for years, but officials say several witnesses finally came forward with new information.

Bostic was arrested in January in Tennessee.
