No, it doesn't. All it means is they've ruled out anything obvious. Toxicology and pathology reports might shed some light.
I should not be up this late tonight. I have an important hearing in court tomorrow. It was contined from 2 weeks ago to give the lawyers time to review all the medical documents. So we will be having more testimony tomorrow. It could go all afternoon. Hopefully it won't. We start at 11. There are at least 3 more witnesses that I know of. I don't know who the other lawyers might try to put on for witnesses. I doubt if they have any....at least any who are credible.
