Dickerson v. State
Annotate this Case
George Kevin Dickerson was convicted by a jury of second-degree murder and attempted second-degree murder. The case arose from an incident on January 8, 2023, when Dickerson called 911 and confessed to killing his mother-in-law, Rose Dennis, and her husband, Andy Martin, with a kitchen knife. Police found Martin dead and Dennis severely injured. Dickerson claimed that an accidental overdose of his antidepressant medication, venlafaxine, caused a violent outburst and a disconnect from reality, leading to his actions.
The District Court of Natrona County oversaw the initial trial. Dickerson entered pleas of not guilty and not guilty by reason of mental illness or deficiency (NGMI). The court ordered a mental examination, which concluded that Dickerson did not have a mental illness or deficiency that would absolve him of criminal responsibility. The court also admitted evidence of a prior statement by Dickerson about provoking Martin to facilitate moving Dennis to an assisted living facility, following a Gleason hearing.
The Supreme Court of Wyoming reviewed the case. Dickerson appealed, arguing that the district court erred in its jury instructions regarding his NGMI plea and the inference of malice from the use of a deadly weapon. He also contended that the court abused its discretion in admitting his prior statement about Martin. The Supreme Court found no plain error in the jury instructions, noting that the NGMI instruction allowed the jury to consider whether Dickerson’s overdose was involuntary. The court also upheld the instruction on inferring malice from the use of a deadly weapon, citing precedent. Additionally, the court found no abuse of discretion in admitting the prior statement, as the district court had carefully considered its relevance and potential for unfair prejudice.
The Supreme Court of Wyoming affirmed Dickerson’s convictions.
