I didn’t know that. I wasn’t aware they could even determine one way or the other whether he had a recent seizure since he died from drowning (as did the other passengers).
I guess the cause still remains unknown.
You may be right. This is the article I read which lead me to believe that epilepsy was ruled out:
http://cbs11tv.com/local/southlake.toyota.crash.2.1471874.html
“And an autopsy released today said there was no evidence he had a seizure before the crash.”
No evidence does not necessarily mean it didn’t happen.
