BOZEMAN, Mont. (AP) — A Manhattan man has pleaded not guilty to vehicular homicide while under the influence for a January crash that killed his wife.

Belgrade Liquor Store owner Michael Soule entered his plea Monday in District Court.

Prosecutors allege Soule was traveling 100 mph on the way home from a Gallatin County Tavern Association dinner on Jan. 25 when he hit a guardrail along Interstate 90, causing a rollover that killed Jennifer Soule.

Court records say Michael Soule's blood-alcohol level was 0.231, nearly four times the legal limit, and that he also had traces of cocaine and marijuana in his system.

District Judge Mike Salvagni allowed Soule to be released on his own recognizance while wearing a drug- and alcohol-monitoring ankle bracelet.
