Two people who were critically injured when a van crashed into a beauty salon in eastern Tennessee have been upgraded to serious condition.

In all, 10 people were hurt Tuesday when a driver who appeared to be having a seizure clipped a car and plowed through the glass front of the salon in Kingston, pinning four customers against a wall and one under the vehicle.

Kingston Police Department spokesman Lt. Gary Nelson said one of those customers, 63-year-old Cheryl Brooks, was listed in very critical condition Tuesday night and needed major surgery. Van driver Richard Ward, who is 52, was also taken to the hospital in critical condition.

University of Tennessee Medical Center spokeswoman Susan Wyatt said Wednesday that the conditions of both have been upgraded.
