Cost is plummeting (Score 1)

In the last few years the cost of this kind of sequencing has plummeted and will continue to do so. As long as it's still within the statue of limitations there, if there is one, in just a handful of years it will cost only a few hundred dollars to sequence both twins and detect all mutation differences between them as well as all epigenetic differences (the methylation that turns genes on and off). So eventually the mounties will get their man.
