648 S.W.3d 235
Tenn. Crim. App.2021Background
- Defendant Demontez Watkins was convicted by a Davidson County jury of first-degree felony murder (merged with second-degree murder), two counts of attempted first-degree premeditated murder (children in an occupied bedroom), attempted especially aggravated robbery, and firearm enhancements; effective sentence: life + 27 years.
- Victim Reginald Ford Sr. was shot outside his duplex late on Aug. 5–6, 2015; autopsy recovered .40-caliber fragments; shell casings and multiple shots into the duplex (where two children slept) were documented.
- Codefendants Davonta Sherrill and Rolandus Denzmore (and others) testified that Watkins was present, possessed a .40, shot the victim, rifled the victim’s pockets, and fled with the others; Watkins gave a pretrial interview admitting presence and firing once in the air but denying he killed the victim.
- Complex DNA mixture was recovered from the victim’s pants pocket; MNPD lab determined the sample required probabilistic genotyping and Cybergenetics’ TrueAllele analysis reported a very high likelihood ratio linking Watkins to the mixture.
- Pretrial litigation: Watkins moved to exclude TrueAllele output (Daubert/McDaniel/Rules 702/703/403), moved to suppress his interview (complaining of police misrepresentations), challenged chain of custody of the pants, and later contested consecutive sentencing as a dangerous offender.
Issues
| Issue | State's Argument | Watkins' Argument | Held |
|---|---|---|---|
| Sufficiency of the evidence for murder/robbery-related convictions | Accomplice testimony corroborated by Watkins’ admissions, DNA match to pants pocket, physical evidence (.40 fragments) supports identity and intent to commit theft/robbery | Convictions rest on uncorroborated accomplice testimony and weak/insufficient physical evidence | Affirmed: Viewing evidence in State's favor, rational jury could find guilt beyond reasonable doubt (Jackson standard) |
| Admissibility of probabilistic genotyping (TrueAllele) | Probabilistic genotyping is a form of DNA analysis admissible under Tenn. Code §24-7-118; trial court properly considered McDaniel factors and found relevancy, reliability, and probative value outweighs prejudice | TrueAllele/likelihood ratios unreliable for complex mixtures (many contributors), insufficient validation, jury confusion/unfair prejudice under Rule 403 | Affirmed: TrueAllele analysis is DNA analysis within §24-7-118; trial court did not abuse discretion admitting likelihood ratios and allowing full cross-examination for weight |
| Denial of motion to suppress Watkins’ pretrial statement | Interview voluntary; Watkins signed Miranda waiver, was not in custody, and did not request counsel; police misrepresentations did not overbear will | Statement involuntary due to false promises/false claims (fabricated video, eyewitness ID, offers to "help" if honest) that coerced admission | Affirmed: Totality of circumstances shows voluntariness; misrepresentations did not render statement involuntary under Tennessee standards |
| Chain of custody for victim’s pants / authentication of DNA sample | Combined documentary proof and testimony (ME, Detective Frank, MNPD lab witnesses) sufficiently tracked pants from ME to property room to lab; no suggestion of tampering | State failed to show unbroken transfer from property room to TBI lab; chain broken so evidence should be excluded | Affirmed: Trial court did not abuse discretion — authentication and practices evidence adequately established identity/integrity of pants |
| Consecutive sentencing (dangerous offender) | Wilkerson factors met: Watkins’ conduct showed little regard for human life (shooting, rifling pockets, shots into occupied bedroom); consecutive service necessary to protect public | Multiple offenses alone insufficient; life +27 years is greater than deserved and not least severe means | Affirmed: Trial court made required Wilkerson findings; consecutive partial sentences within-range and not an abuse of discretion |
