Demario Johnson v. State of Tennessee

Post-conviction petitioner, Demario Johnson, challenges his 2008 conviction of first degree murder and resulting sentence of life imprisonment. On appeal, he alleges the following claims of ineffective assistance of counsel: (1) failure to investigate and present evidence of his mental health history; and (2) failure to challenge the medical examiner’s opinion regarding the victim’s cause of death. Discerning no error, we affirm the judgment of the post-conviction court.
