An appeals court has upheld the murder conviction of a man accused in a 1989 beating that left a woman in a coma until her death in 2001. Louis Joseph George is serving a life sentence in the death of Michelle Steven. The investigation became a "cold case" for several years until a fresh review of the case linked George's fingerprints and DNA to the crime. George was convicted last year. He appealed the conviction, arguing that the judge should have delayed the trial to allow George's DNA expert to testify and accused the judge of mishandling the jury selection process. A three-judge panel with the state's 3rd Circuit Court of Appeal set aside those arguments and upheld the conviction in an opinion released Wednesday.
