The only issue I have with the story is that it says the murder victim was killed when the gas was shut off on the heater and turned back on. The room filled up with gas and he suffocated. This could not happen in real life. Those heaters have a valve called a robertshaw valve that has a safety mechanism to prevent something like this from happening. If you shut the gas off and the pilot goes off, the valve automatically shuts off the main gas until the pilot is re-established.
