State of Tennessee v. Douglas Marshall Mathis

The defendant, Douglas Marshall Mathis, was convicted of first degree murder and sentenced to life imprisonment. In this appeal, he contends: (1) that the evidence is insufficient; (2) that the trial court erred by giving an irrelevant definition of "knowing" as a part of the instructions to the jury; (3) that the prosecutor's comments during closing argument were improper; (4) that he was denied the right to a fair and impartial jury; and (5) that the trial court erred by admitting certain evidence. Because the state's closing argument was improper and the error cannot be classified as harmless, the judgment of the trial court is reversed and the cause is remanded for a new trial
