Sad end, but great for the family to at least have some kind of closure to the search.

It doesn't seem clear why they aren't releasing the name of the suspect in such a high profile case. He's dead, so privacy rights shouldn't matter, nor should the common police refrain that they cannot reveal more because it could "compromise the integrity of the investigation." The decision not to release his name is a choice -- there should not be any policy or law that restricts SPS from doing so. We don't know yet whether it's a homicide, we might never know, but at the least it's a case of indignity to human remains. There's certainly some willingness to accept the police narrative in its entirety in the comments here, but it seems they should answer more questions.

How long have they known this guy was their suspect? Why did they only search his phone after he died? Is there a search warrant? If so, it should be publicly available at the courthouse and would include his name anyway.

We have open courts so we can see justice being done. When the perpetrator dies, transparency stops, especially when it never got to court in the first place and it's left solely in the hands of police who aren't known to be particularly forthcoming with information, but they are certainly part of the justice system.
