The Nebraska Supreme Court has rejected a motion for post-conviction relief by an Omaha man sentenced to life in prison for the 2003 shooting death of another man.

Edward Robinson Jr. was convicted of killing 28-year-old Herbert Fant in February 2003 after arguing with him in north Omaha. Fant was found dead in a car parked in a restaurant lot and had been shot several times in the chest and abdomen.

The state's high court affirmed Robinson's conviction on direct appeal in 2006, and he filed a motion for post-conviction relief. Such motions are filed after all other appeals have been exhausted.

Robinson argued in his post-conviction appeal that he was denied a fair trial because his lawyer was ineffective, but the Nebraska Supreme Court rejected those arguments Friday.
