Honestly....... MC's testimony in court is hypothetical. There is no solid evidence that is backing anything his saying. His just making guess work based on the evidence he saw. Honestly, after that serial killer case, he seemed to have lost his professionalism. And that was why he was used by the lawyer. Even when the lawyer asked him a question that was not part of what they agreed on, he should have shut it down and refused to answer. He just clearly stated in a law court that the lady was the killer without indispensable evidence. And he will be held to that testimony even after the case is over.
