I haven't yet. I live in colorado now and it makes it a little harder to research and I'm not sure what county he died in. I was told the car wreck was on rt. 22 comin g up from pittsburg. The 1940 census should be out soon maybe that will shed some light. The 1930 census I have lists Jennie as Sadie Gibson and I've seen it also as Sarah Gibson. I was told the wreck was really bad as he was traveling at a high rate of speed and hit a tree forcing the engine into the front seat. I thought since it was so bad I might find it in old newspapers but havent yet. I need to check old court records to find out when and why he was released from a life sentence.
