Murdoster 

A portmanteau of both murderer and imposter, where someone has not only been proven to have murdered someone in some way, but also having taken on someone else's life, appearance, and ego. Both deeds don't have to be related to each other in order for a person to be a murdoster.

An example of this word being used in a sentence are as follows:
It could be used as a condensation of murderer and imposter, having the same uses as both simultaneously would entail: You murdoster! You not only killed someone in cold blood, but you also impersonated someone to cover your tracks.
