Not so patiently waiting for a mechanism of death to be announced. LE said it's been concluded and they've been freely sharing other info as of late (though the info shared seems they are trying to deter public speculation moreso than fully inform the public).
If COD was blood loss via laceration, I could start accepting more possibilities. If COD is something like gunshot wound to head/abdomen, or a drug related overdose or poisoning*, I would still have my reservations.
*I could imagine certain ingestions could cause esophageal/gastric bleeding i.e. if it was a caustic liquid like a bleach, but I am not confident how much bleeding that would produce. Painful poisoning suicide is also, statistically, not a "first choice" method for Justin's demographic.
