CLAYTON, Mo. -- A St. Louis man will spend the rest of his life behind bars for killing another man in revenge outside an auto parts store.

Michael Crawford was sentenced to life without parole Friday in St. Louis County. He was convicted in July of killing Dion Butler, 29, outside the Advance Auto store in Jennings in October 2000.

Authorities say Crawford, 28, opened fire on the victim and a second man as revenge for the 1998 murder of his brother, Anthony Crawford. Butler was arrested in that shooting but was never charged.
