I've been thinking about the word "sensitive" too and I agree with most mulled about above:
-'sensitive' in that it pertains to a person they are interested in as a perp and is information the the perp is unaware of. Eg finger prints of a known person somewhere where they shouldn't be etc.
-'sensitive' as in the details are gruesome and horrific and LE are sparing us the torment of knowing. (Although you'd think this would come with a definite public safety announcement.)
-and finally 'sensitive' because it suggests suicide which carries its own torment to family and friends. It is a very personal detail to be splashing about without tox details to back it up.
As Pickard mentioned a few more weeks for results I guess we're in it for the long haul. Well, at least we know we have played out every and any scenario under the sun with the scant information we have
PS: annoyingly, the mention of 'taking a bus' in the return text was mentioned again, now, from the horse's mouth... This snippet just doesn't mesh with the 'suicide' angle. The carpool buddy writes back "how long", CD writes "about 10 minutes, I'll take the bus", buddy writes "we'll wait". If you are contemplating suicide and want a few hours of alone time to make it happen, wouldn't you reply to that final text? To stall the panic being raised? To prevent calls to the house, the husband or even the carpool detouring around to see if her car has broken down etc.
