A 23-year-old Washington woman died Saturday afternoon in a West Virginia hospital after an all-terrain vehicle accident.

Mariah Zambelli was pronounced dead at Broaddus Hospital in Phillippi, Barbour County.

The accident happened about 2:14 p.m. at King Knob, a motorsport park outside Phillippi, said Phillippi fire Chief David Utt.

Zambelli and an unidentified man were on a four-wheeler going up a high wall when the vehicle rolled over the wall. The man who was operating the vehicle was not injured, Utt said. An emergency helicopter was called, but Zambelli was taken by ambulance to the hospital.

Brett Carpenter, chief deputy sheriff, said Tuesday that no information, including the name of a person charged in the incident, would be released until the investigation is completed.
