The high court, without comment Monday, rejected the appeal from Terry Edwards. He was convicted and condemned in 2003 for the fatal shootings of a Balch Springs Subway store manager and an employee. Killed were 34-year-old Tommy Walker and 26-year-old Mickell Goodwin.

Evidence showed Edwards had been fired from the store a few weeks before the shootings in July 2002. About $3,000 was taken in the holdup.

Edwards had argued in earlier unsuccessful appeals that his Dallas County trial judge gave improper instructions to jurors during jury selection, violating his right to an impartial jury.
