Another freeper pointed out that insulin overdose can cause potassium deficiency (hypokalemia). We've heard that the initial cause of Terri's heart failure was potassium, which has been explained by bulemia.
I have been cross-posting a snippet of a court case where the murder weapon used was insulin in the hopes that some medical experts would think this out some more.
Just what I was thinking. Was there anything on the night of the event. However, it is my understanding there was no glucose level done the night of her admission when the event occurred. Too bad about that if true.
