420 P.3d 172
Wyo.2018Background
- Doyle Gabbert committed multiple violent offenses over three days in August 2016 while on parole, including shooting at a motorist, brandishing a gun and demanding keys, stealing vehicles, and attempting further theft while fleeing police.
- Charged with eight felonies: three counts aggravated assault/battery, one count aggravated robbery, two counts theft, unlawful possession of a firearm, and possession of a deadly weapon with unlawful intent.
- Gabbert pleaded not guilty and not guilty by reason of mental illness or defect (NGMI). The court ordered a statutorily required evaluation at the Wyoming State Hospital.
- Dr. Alex Yufik, the designated forensic examiner, diagnosed antisocial personality disorder and an amphetamine-type substance disorder, concluded Gabbert’s psychotic symptoms were substance-induced, and opined Gabbert retained capacity to appreciate wrongfulness and conform conduct to law.
- After a bench trial the court found Gabbert guilty on all counts and rejected the NGMI defense; Gabbert appealed, arguing the court erred in finding he failed to prove NGMI.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the district court erred in rejecting Gabbert's NGMI defense | Gabbert argued the court wrongly found he failed to prove by a preponderance that, due to mental illness/deficiency, he lacked substantial capacity to appreciate wrongfulness or conform conduct | State argued evidence (including examiner's opinion and circumstantial evidence of awareness and evasion) supported rejection; standard of review should defer to factfinder | Affirmed: viewing evidence in light most favorable to State, a rational trier of fact could conclude Gabbert failed to prove NGMI by a preponderance |
