HUBBARD, Ohio - The Ohio State Highway Patrol says it believes an Arizona man was driving drunk when his semi-tractor trailer crashed along Interstate 80 in Hubbard, killing a woman who troopers believe was his fiancee.

Troopers say Ademayowa A. Saint, 46, of Glendale, Arizona was driving toward Pennsylvania at around 6:30 p.m. Monday when his truck went off the road, struck a ditch, and several trees before jackknifing.

Authorities have not released the name of the woman who was in the sleeper berth of the truck, but believe she was Saint's fiancee. The woman died in the crash. Saint was not injured.

The Ohio State Highway Patrol Crash Reconstruction Unit investigated the accident.

According to troopers, Saint was under the influence of alcohol and illegal narcotics at the time of the crash.

Saint was booked into the Trumbull County Jail on charges of vehicular homicide, possession of marijuana, having an open container, and operating a commercial vehicle while under the influence.

During his arraignment on Tuesday, Saint's bond was set at $50,000.

Eastbound I-80 was down to one lane after the crash but has since re-opened.

Any witnesses to the crash are asked to contact the Ohio State Highway Patrol Warren Post at 330-898-2311.
