The failure or success of an attorney isn't measured by how cases were "won" or "lost" To use this case as an example, if Casey is ultimately sentenced to less than 10 years in prison, I would say that her defense attorney has done a good job, even though the defendant technically "lost", i.e. - was found guilty of something.
And by the way, the chances of Casey doing less than 10 years in prison are not as remote as many would think: LE doesn't have one single shred of evidence that Casey was criminally responsible for Caylee's death. And the DNA likely won't provide LE with a cause of death no matter what else it might tend to prove.
What the evidence proves (so far) is that Caylee is dead, that Caylee died while under the general care and supervision of her mother Casey, and that based on all of the witness statements gathered, that Casey likely concealed Caylee's body somewhere. But there's no cause of death in any of the evidence.
