"Getting away with blue murder"
Implies a person has gotten away with something so bad that they were expected to get get caught for.
If you a royal was murdered it would be assumed that the culprit would be apprehended as there would be an unusual large manhunt undertaken making getting away with this murder harder than the murder of a normal person. And since royals are known as blue bloods this is were the term originated.
The full expression is: like a (lightning) bolt from the blue, meaning the rare instance of a bolt of lightning that strikes a long way from its cloudy source, seemingly out of a clear blue sky.
