I would like to see the numerical toxicity levels of cola he came up with. Sounds like an awful coroner to infer something he cannot measure and can only glean from unscientific claims. A test for cola metabolite? Really? Maybe he was confusing cola with coke.. yes, that we can measure. Who hired this guy? He has questionable credentials, I would infer.
2 gallons a dy of anything can probably kill you
The direct evidence does seem a bit slim. However, there’s probably enough indirect evidence for the coroner to draw the conclusions he did — or at least to put them within the realm of plausibility. (Momentarily setting aside the possibility of media nonfeasance, misfeasance, or malfeasance in the coverage of this story.)
The toxicity of caffeine is quite well known, as is the number of Calories in a gallon of Coke. Also, she had her teeth removed, because the coke dissolved the enamel. That’s got to correlate with other health problems.
