Morag, I have thought about this over the past several days, and I can only hope that the "ruling" on Friday might be a way to try to draw the real killer out. Maybe they feel like they're dealing with someone egotistical or who would eventually want to take credit or be known for having done this. The suicide ruling would probably get their goat.
LE doesn't operate this way. Nothing to suggest anyone is trying to draw anyone out.
