A pre-dawn collision Friday between a Freightliner and a Chevy van on the Will Rogers Turnpike has resulted in the death of one of the drivers.

OTTAWA COUNTY – The cause of a two-vehicle collision just outside of Miami early Friday morning remains under investigation by the Oklahoma Highway Patrol and has resulted in the death of one of the drivers.

According to an OHP report by Trooper Jason McCarthy #474 of the XA Detachment of Troop L, the collision occurred at approximately 2:25 a.m. eastbound on the Will Rogers Turnpike about three miles west of Miami.

A Freightliner tractor driven by Darnell Frazier, 47, of Battlefield, Missouri, and a Chevy van driven Erika Solle, 81, of Lebanon, Tennessee were both traveling eastbound when the truck struck the van from behind causing both vehicles to leave the roadway to the right.

The report says both vehicles then re-entered the roadway, coming to rest on the inside shoulder against a barrier wall.

Solle's condition is described as "apparently sleepy" in the OHP report, while Frazier's is listed as unknown.

Frazier was not injured.

Solle was pinned in the pre-dawn accident and then freed and transported by Miami EMS to Mercy Hospital in Joplin in critical condition Friday with trunk and internal injuries.

In an update issued by OHP Sunday, Solle was pronounced dead as a result of her injuries by Newton County Medical Examiner Dale Owen July 16 at 10:14 a.m.

Road conditions in the report were listed as dry and the weather as clear.

Trooper McCarthy was assisted by Trooper Shawn Cummings #450 of the XA Detachment of Troop L, Miami Police Department, Miami Fire Department and Miami EMS.
