The Mississippi Court of Appeals has upheld the conviction of Matthew Nash in a shooting death in 2007 that resulted in two of his brothers also being sent to prison for life.

Nash was convicted by a jury in Warren County Circuit Court in March 2009 in the killing of Justin Maurice Harris.

Prosecutors said he did not carry or fire a weapon but knowingly went to Harris’ Grammar Street home with his brothers, Anthony and Armond Trevillion, in the early hours of June 17, 2007, after they had argued with Harris earlier in the evening at a Washington Street club.

The higher court heard Nash’s appeal in July. The unanimous decision, issued Tuesday, noted that Nash’s attorney filed the appeal for the court to review trial records and did not claim specific, arguable issues from the original trial.

“This Court has made a diligent search of the entire record, and we have found no error in the circuit court’s proceedings,” the court ruled in affirming the conviction.

Nash, Anthony Trevillion and Armond Trevillion were each found guilty of murder, shooting into an occupied dwelling and two counts of aggravated assault. They were sentenced to life in prison on the murder charges plus more than 50 years each on the additional charges.

A fourth brother, Alonzo Trevillion, was found not guilty in December 2009, and charges against another man, Rufus Armstrong, were dismissed following Alonzo Trevillion’s trial.
