WICHITA - A prominent Tulsa attorney was among the three people killed in a crash in Wichita Sunday.

Wichita Police believe a medical condition may have played a role in a fiery crash that killed three people.

The accident occurred around 1 o'clock Sunday afternoon on the eastbound exit ramp at Kellogg and Oliver.

Police released additional information this morning. Officers said the SUV was going 70-75 mph when it crashed.

Police say the driver was Kurt Ackermann, an assistant city attorney for the City of Tulsa. A memo to Tulsa City Hall employees, released by Tulsa's Mayor, said Ackerman's wife and mother-in-law also died in the crash. Ackermann's mother-in-law is from Lyons, Kansas.

Kurt Ackermann, 57, had worked with the City of Tulsa for eight years.

Witnesses say they saw the small SUV veer off the road and then over-correct before crashing into the large overhead road sign structure. The car then burst into flames.

Eastbound lanes of Kellogg were closed for more than eight hours Sunday. Traffic was diverted to Hillside.

The westbound lanes of Oliver at Kellogg were closed for a time, but have also since been reopened.

Statement from Tulsa's Mayor on Ackerman's death:

It is with great sadness that I share with you that yesterday we lost a
long-time city employee, Kurt Ackermann, Assistant City Attorney.

Kurt, his wife, and a third person believed to be his mother-in-law,
were killed in a car accident at approximately 1 p.m. on Sunday,
December 21, in Wichita, Kansas.

Kurt worked diligently in the City's Legal Department for four years
in the sphere of Zoning and Historic Preservation, as well as in tax
increment financing. He acted as a legal advisor for the Board of
Adjustment, Tulsa Preservation Commission, and the Park Department.
Before transferring to the City Attorney's Office, Kurt worked for
nearly eight years as a zoning official with the City's Development
Services.

Kurt was deeply appreciated by both his co-workers for his excellent
people management skills, a great sense of humor and the knowledge of the law. Many of us had an opportunity to work with Kurt and see his
deep dedication to the City of Tulsa. We will all miss him greatly.
