Forensic Toxicologist - Lethal Injection Dose Failure Science

URGENT: I’m working on a story for The Times of India examining the science behind Christa Pike’s botched execution and a central question: How can two lethal-injection doses fail? I’m looking to speak with someone with relevant medical or scientific expertise who can help explain what may happen physiologically when a lethal injection does not proceed as expected. I’m particularly interested in understanding the science of drug delivery, how the body responds to the drugs involved, and what could potentially cause a lethal dose to fail. If you have relevant expertise or can recommend someone, please DM me.
