According to newspaper articles Jack Seavers was struck from behind by a "tractor-trailer rig" and his car exploded. The truck driver was killed as well. This happened at 1:15 pm (July 30, 1984.)
Mr. Seavers was part of a road-striping crew at the time. Authorities weren't sure what caused the accident but skid marks indicated that the truck driver did not apply the brakes until after the impact. The truck then overturned and caught fire.
They believe Mr. Seavers was killed instantly.
Note: The other posters are right, however. When asking for genealogical help you should provide as much info as possible. I had some extra time to try to figure out your question, but you should try to make it as easy as possible to find info, not harder. :) All questions should have names, dates, and locations, if possible.
