"What?
Paraquat?" Doctor Shrek's face drastically changed, for he certainly knew what Paraquat was -- a herbicide, commonly referred to as pesticide.
Whoever drank Paraquat was bound to die. Moreover, there was no antidote for such a poison. Once it was consumed, the victim would not die instantaneously, but would suffer from heart and lung failure.
"Impossible!"
Hearing William Cole's statement, Doctor Shrek immediately shook his head, "If one had consumed Paraquat, then how could they possibly live for three more years? They wouldn't even survive for three more days."
"His heart and lungs were seared, completely depleted. Although it resembled the effects Paraquat would have, it was absolute not Paraquat!"
"What nonsense as you talking about?"
Russell Booth hollered, "How on earth could Uncle Campbell have been poisoned with Paraquat? Mind your words!"
