Behavior of witnesses and suspects is significant when solving murders. MM found herself to be a murder suspect and complained about it in court. What did she expect? She was sleeping with her friend's husband, leading him on, commiserating about marriage, professing their love and suddenly, her friend is murdered. She kept contact with him even after the murder and her performance in court leaves much to be desired - particularly in terms of being forthright. She is deception, evasive and cutesy. I bet she can talk for two hours and say nothing.
