Not directly for sure, and as another HNer wrote there's some Darwin involved. I didn't know there had been an investigation for possible murder, so thanks to all HNers who pointed it out. It seems however from the latest articles I could find that the murder suspicion has been dismissed and the man death ruled as an accident. What however is strange is that the couple worked both at John Deere, and the man was an engineer with a high degree of education, which doesn't seem that compatible with the level of stupidity needed to drink a fish tank cleaner. Unrelated, but looking around i found that the two once sued their employer for sex and age discrimination against the wife. https://www.leagle.com/decision/infdco20140721507 https://www.leagle.com/decision/infdco20140721507
