State of Tennessee v. Zachary Everett Davis

When he was fifteen years old, the Defendant, Zachary Everett Davis, killed his mother by hitting her in the head with a sledgehammer numerous times and attempted to kill his brother by setting the family’s residence on fire. After determining that the Defendant was competent to stand trial, the juvenile court transferred the Defendant’s case to the Sumner County Criminal Court. The Sumner County Grand Jury indicted the Defendant on charges of first degree premeditated murder, attempted first degree premeditated murder, and aggravated arson. After a competency hearing, the trial court determined that the Defendant was competent to stand trial. After a suppression hearing, the trial court concluded that the Defendant knowingly and voluntarily waived his rights prior to an interview conducted by the Sumner County Sheriff’s Office. A Sumner County jury found the Defendant guilty as charged, and the trial court ordered the Defendant to serve a life sentence for his first degree murder conviction. After a sentencing hearing, the trial court ordered the Defendant to serve twenty years with a thirty percent release eligibility for attempted first degree murder and twenty years with a 100% release eligibility for aggravated arson; the trial court ordered the twenty-year sentences to run concurrently with each other but consecutively to the Defendant’s life sentence. On appeal, the Defendant argues that the trial court erred in: (1) denying the Defendant’s motions to be declared incompetent; (2) denying the Defendant’s motion to suppress his statement to the Sumner County Sheriff’s Office; (3) denying the Defendant’s motion for mistrial after the Defendant testified on direct and cross-examination that he did not commit the offense; and (4) sentencing the Defendant to a de facto sentence of life without parole in violation of the Eighth Amendment of the United States Constitution. After a thorough review of the record and applicable case law, we affirm.
