Better answer: He wasn't murdered. Neither Mr. Murphy nor anyone can overcome the laws of chemistry and physics. This is sort of high school level science, so those who believe Mr. Murphy are likely to believe a lot of things outside their knowledge.
The tip-off is that the promoters either never have a scientific explanation of the details, to show why it is or would be possible, or their explanation is incomplete. Or they begin to act squirrelly if reasonable questions are asked. Questionable accomplishments even get significant scientific and industrial notice, before they mysteriously dwindle into obscurity (usually related to odd financial maneuvers of the proponents). An example of this was Andrea Rossi and his cold fusion gadget, the E-Cat. (Here's a good run-down: https://skepticalinquirer.org/2019/05/rossis-e-cat-expose-of-a-claimed-cold-fusion-device/) We had the E-Cat come up for consideration at my company, but making sense out of it was elusive. My best guess at the time was that the process might have been the stimulation of beta decay in the construction materials, transforming nickel into copper. Alas, no joy.
What if he was channeling power from the Dark Dimension? What if he had a racecage filled with super-hamsters? What if he had an accomplice pull his car with an invisible fishline? If you want to play the "what if?" game (a child's game), I can go on indefinitely. The point is, what he touted is not scientifically possible and he evidently never explained why it could be. It's just another perpetual motion hoax.

I want to argue but your reasoning is solid. Slight of hand.

Our understanding of chemistry and physics. What if he discovered something an alien race figured out a long time ago?

You figured it out! Eureka! Water fueled cars, here we come!
