Jackson, Miss. The state Court of Appeals has upheld the conviction of Christopher Lee Baxter in the 2010 death of George County Sheriff Garry Welford.
Baxter and his girlfriend, Brandy Nicole Williams, were convicted in 2012 of capital murder. Each was sentenced to life without parole.
Welford was struck by a pickup truck in which Williams and Baxter were fleeing from authorities July 21, 2010. Baxter was sought on an arrest warrant issued after he missed a sentencing date for drug convictions.
Welford was putting spikes at an intersection near the Alabama line to stop the truck and end a high-speed chase.
After an all-night search, Baxter and Williams were captured the next morning at a mobile home about six miles north of the scene.
