[King Kong]

It's been awhile but I've seen a lot of stuff about this case.  The stationary the note was written on. Wasn't it the mother's work stationary or something? Plus knowing the exact bonus amount for the ransom,  was always strange to me.  Then she was found in the basement.  Why even write a ransom note to being with,  if she had already passed. Maybe trying to stage something, a cover up. 

Like I said it's been awhile since I've followed this.  Not really sure who I lean towards as a prime suspect.
