Somebody upthread brought up the question of identifying these remains--I can't find the post I wanted to reply to now.
I'm not LE and this is just my observation from following a bunch of cases here--but medical examiners/coroners rarely make an ID these days by anything other than forensic methods like dental, DNA, or fingerprints. Matching tattoos, ID on the body, visual identification might tell them what they think the answer is, but they almost always wait for confirmation before making an announcement.
Also, in most states, only the ME/coroner can make that determination. The LE on the scene can be positive about who a particular victim is, but until the ME confirms, it's just a guess.
It's possible that they will make a preliminary announcement saying something like "pending confirmation," but it seems to be less and less common.
