The Mississippi Supreme Court has declined to hear an appeal from a Scott County man convicted in a 2010 slaying.
The state Court of Appeals upheld Timothy Joseph Patterson's murder conviction and life sentence.
Patterson was convicted in Scott County in 2011 in the death of 28-year-old Michael Guy.
Prosecutors say Guy was shot to death May 9, 2010, at a home in Morton where Patterson and others were watching a fight on television.
Defense attorneys say Patterson never intended to harm Guy.
The court rejected Patterson's arguments that his attorney should have done a better job and that prosecutors didn't prove his guilt.
Prosecutors say Patterson shot Guy once in the head and then stood over Guy and shot him in the head a second time.
