No civilised justice system in the world is getting to murder from these facts.
Manslaughter via negligence if you're feeling really lucky
>To avoid the need for reliance upon common law interpretations of what felony conduct merges with murder, and what offenses do and do not qualify for felony murder, many U.S. jurisdictions explicitly list what offenses qualify in a felony murder statute. Federal law specifies additional crimes, including terrorism, kidnapping, and carjacking.
Note that US states are not consistent on what is second degree murder. I cannot find a federal definition (I'm not a lawyer - this should be seen as me not knowing the right search terms). There are many other countries with their own definitions of murder which are all slightly different.
Felony murder statutes disagree.
The regulators are also culpable since the design of the system was in the public domain before the second crash and they did nothing about it.
