The problem with a clone of a person murdering the original is that you’ll find only one set of fingerprints and one set of DNA markers.
So, a murder will get flagged a suicide by the automatic systems, or it will get placed in the hard cases queue.
The investigators in that queue are really good at their jobs. As if they were born to do the job.
But they weren’t born to do it.
They were grown. In tanks.
And every so often, one goes astray, and kills another.
The rest circle the wagons quickly.
Call it a suicide.
