BOSTON — The highest court in Massachusetts has refused to grant a new trial to an Oklahoma man convicted of killing the manager of a fast food restaurant.
Quillie Merle Spray III, of Anadarko, Okla., was convicted of first-degree murder and sentenced to life in prison in the death of Sherylann Miller at a KFC-Taco Bell under construction in Clinton in 2000. There was no apparent provocation or motive.
Miller was stabbed to death by Spray, who was a tile setter working at the restaurant. Spray claimed his sister-in-law, who was also working on the tile job, killed Miller.
In his appeal, Spray argued that his trial lawyer was ineffective for failing to use an insanity defense.
The Supreme Judicial Court on Thursday rejected Spray’s arguments and affirmed his conviction.
