Here's how this works.  I'll give you a riddle or a crime scene.  You have 21 posts worth of questions you can ask as a whole.  I'll ignore other questions until I answer the first.  Think wisely to ask the right questions and get your answers.  Everything confidential or not listed can be asked about.

So, the first is this.  A man was killed . The date and time are confidential.  We know several people who were there of varying age and type, but the two suspects whose names start with S are more likely than the others.  Motives are confidential.  The murder weapon was a shard of what looks like a mirror, that sliced the neck after what looks like a struggle.  The man in question was recently going through a divorce.

Ok, you can ask the rest.

They have to be involving the riddle.  But they can be about anything involving the riddle.

The answer to this riddle is complex.  That's what it is.  :P

The answer has to be at least more than two words, but not a paragraph.  It must tell me the person who did it.

Your wasting your questions and everyone else's.
