A Vincennes murder trial has been pushed back for a third time. Court documents say 53-year-old Robert Baldwin was originally set to appear in court this week. He is accused of killing his five-year-old son Gabriel in April. Baldwin faces charges of murder, strangulation and domestic battery. The documents say Baldwin's attorney has asked for a change in venue, with arguments and testimony re-scheduled for January. The Knox County Prosecutor is seeking life without parole.
