354 So.3d 308
Miss. Ct. App.2022Background
- On June 25, 2016 two boats collided bow‑to‑bow on Bayou Caddy; passenger Vanessa Mauffray (on Necaise’s boat) was injured and later died. Defendant Eugene Butler piloted the other boat.
- Investigators and expert reconstruction testified Butler was on the wrong side of the waterway, traveling at an unsafe speed, and violated multiple navigation rules; Butler claimed a broken shift linkage limited his ability to change gears and denied seeing Necaise.
- Necaise gave varying statements about speed, distance, and where he fell; a presumptive drug screen suggested prior marijuana use but a confirmatory test was negative. The trial court excluded evidence of Necaise’s alleged marijuana use.
- Butler’s blood drawn ~4 hours after the collision tested positive for inactive THC metabolite and Delta‑9‑THC (3.7 ng/ml); experts disputed whether that level showed impairment. Butler was never charged with boating under the influence.
- A jury convicted Butler of culpable‑negligence manslaughter (amended indictment to habitual offender) and sentenced him to 12 years. He appealed raising three issues: (1) improper grant of the State’s motion in limine excluding evidence of Necaise’s drug use, (2) insufficiency of the evidence for culpable negligence manslaughter, and (3) verdict against the weight of the evidence.
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Butler) | Held |
|---|---|---|---|
| Whether the trial court properly granted the State’s motion in limine to exclude evidence of Necaise’s drug use | Evidence was irrelevant and more prejudicial than probative; confirmatory toxicology was negative; exclusion appropriate under evidentiary rules | Excluding Necaise’s admission of smoking marijuana hours earlier deprived Butler of impeachment and denied his ability to present his defense | Affirmed — exclusion not an abuse of discretion: no proof Necaise was under influence at collision (Rule 401/402); excluded under Rule 608(b) as not probative of truthfulness |
| Whether the State presented sufficient evidence of culpable‑negligence manslaughter | Presented expert reconstruction, testimony that Butler violated lookout and navigation/speed rules, and circumstantial factors supporting gross negligence | Argued evidence insufficient; no proof Butler was intoxicated and collision could be a tragic accident | Affirmed — viewed in light most favorable to prosecution, reasonable jurors could find culpable negligence beyond a reasonable doubt |
| Whether the verdict was against the weight of the evidence (motion for new trial) | Jury’s credibility determinations entitled to deference; evidence did not preponderate heavily against verdict | Asked for new trial as verdict was against the weight of the evidence | Affirmed — appellate waiver for cursory treatment; on merits, no exceptional case justifying new trial and trial court did not abuse discretion |
