Now, if something had been poured into the engine to contaminate or dilute the motor oil for example, THAT could have caused it to fail.
When you drain the oil, pay attention to its appearance (thin or thick, normal color or not) and the smell (like gasoline or some other solvent), and check the oil for having sand or some other substance in it, other than some metal debris from the engine failure itself.
X2 Mark, I was wondering the same thing if something was actually poured in the engine to cause this mishap.
