I am trying to locate my sister's grave and any information I can find regarding her death Sept 23 1956 in Killeen, TX. Unfortunately, anyone that knew the complete story has passed away. I'm going to be in the Killeen area in August and would like to locate her grave and perhaps put a marker up.

I also want to find any information about her death. All I know is that my parents were at a racetrack (cars, I guess) one car went off the track and hit spectators.

Any help anyone can give me would be appreciated.
Thank you in advance
