Dorothy's Killing

Some one killed dorothy simons, though there were still many questions. For example, it was unclear whether her murder was premeditated. Dorothy's death seemed so violent and so well covered up that i wonder if the killer was experienced. You could have somebody who has been involved in this body disposal process before. If you have a reasonably inte a person who is thinking about, i want to commit a crime for whatever reason, how am i going to get away with it? That's your intelligent offender.
