Background
Alexandria Marie Griste was indicted for first-degree murder after she shot and killed Corey Lyles outside her Oxford home on June 7, 2022. Griste and Lyles lived together with Griste’s two young daughters and had a history of domestic violence. That day, the couple exchanged hostile messages and argued at home. Later, after Lyles returned to the house, Griste fired her pistol; Lyles was unarmed and had not entered the house.
In statements admitted during the State’s case, Griste said she feared Lyles and believed he was coming toward or trying to enter the house. She said she fired warning shots before shooting him through a window in the door. A jury found her guilty of manslaughter, and the circuit court sentenced her to twenty years in Mississippi Department of Corrections custody.
The Court’s Holding
The Court of Appeals affirmed. Griste could not invoke the Weathersby rule to obtain a directed verdict because she did not testify or present other defense testimony. Her unsworn police statements, though introduced by the State, did not establish her version of the homicide for Weathersby purposes.
The court also held that the circuit court acted within its discretion in excluding evidence of Lyles’s 2016 conviction for enticement of a child. Although that offense is statutorily designated a crime of violence, the record contained no evidence that Lyles committed a violent act in connection with it. The trial court permissibly found the conviction’s unfair prejudice substantially outweighed its probative value. Finally, the evidence supported an imperfect-self-defense manslaughter instruction and was legally sufficient to sustain the verdict; the verdict was not against the overwhelming weight of the evidence.
Key Takeaways
- A defendant who presents no trial testimony cannot rely on unsworn statements introduced by the State to invoke the Weathersby rule.
- A victim’s prior conviction may be excluded under Rule 403 when its prejudicial effect substantially outweighs its relevance to claimed self-defense.
- A murder indictment gives statutory notice that the jury may be instructed on manslaughter as a lesser-included offense when supported by the proof.
Why It Matters
The decision reinforces the narrow scope of the Weathersby rule and confirms that a defendant’s out-of-court statements alone do not trigger it. It also illustrates that an asserted self-defense claim can support an imperfect-self-defense manslaughter instruction when the jury could find the defendant’s fear genuine but unreasonable under the circumstances.
