It is the intersection where three family members died two weeks ago after racers collided with their van.
Fifty-two-year-old Carl Findley from Dakota was traveling west on Riverside approaching Huffman. Witnesses say he appeared to be unconscious; he swerved and then hit a guard rail.
Police believe the man had some sort of medical condition. Findley's death appears to be a result of a medical crisis. An autopsy will take place Monday.
