Reputed U.S. mobster Anthony "Big Tony" Moscatiello was convicted of first-degree murder Wednesday in the 2001 slaying of a prominent Florida businessman during a power struggle over a lucrative fleet of gambling ships.

The jury also found Moscatiello, 77, guilty of murder conspiracy in the shooting death of Konstantinos "Gus" Boulis, founder of a chain of casinos and restaurants. Evidence showed Boulis was killed by a mob hit man, and Moscatiello was accused of ordering the slaying. He faces a possible sentence of death or life in prison.

Moscatiello's wife fainted after the verdict was read.
