Are you suggesting the cop who has the same former name of Barb, who may be her ex?
If that were so, it would explain a lot wouldn't it?
Like how the cops found out about the partying on Friday night, why the Prosecution wouldn't put Barb on the the stand, and why LE had to find a patsy - and quick! All of this is speculation,I don't know that such a connection exists. But it would explain a lot of riddles.
