A Tyler woman was sentenced to 40 years in prison for the 2015 murder of her boyfriend.

Louise Anderson, 49, pleaded not guilty in a Smith County Court on Friday to the murder of 58-year-old John Wayne Pierce.

A Smith County jury found Anderson guilty and sentenced her to 40 years in the Texas Department of Criminal Justice.

Pierce died from a gunshot wound in Dec. 2015 after Anderson shot him once in the left side of his torso after a domestic argument outside of a Game Room on Highway 31 in Tyler.

According to the arrest warrant, Anderson stated Pierce struck her in the face, but there were no obvious injuries on her and she did not request EMS at the scene.
