you wouldnt need a new IV just inject into the existing one. While high levels of digoxin could be detected it would not commonly be tested for in a patient that was not on the drug and died suddenly. Insulin would be almost impossible to test for.
What about succinylcholine?
Good point.
I completely missed that.
He only killed people on IVs.
Just recently, a male nurse in Japan was convicted of mass murder.
He got the death penalty, which surprised me.
I thought Japan ended the death penalty after WW2.
