Lexington police said in a statement that they charged Marquis D. Thurman and Adrian L. Dunn after determining both men fired shots during a robbery Monday night at the girl's home. Police say 2-year-old Nova Marie Gallman died from a gunshot wound and her mother's boyfriend was wounded.
Media report the men, who had already been charged with assault and robbery in the case, pleaded not guilty to those charges on Wednesday. They'll be arraigned on the upgraded charge later. Online jail records don't list an attorney for either man.
The girl's mother told investigators that two men forced their way into the family's home and demanded money before shots were fired.
