It is unfortunate that we allow small local sheriff and police depts. to investigates homicides just because the crime occurred in that area. It leads to mistakes in almost every case I have followed. Some murders are never solved because of mistakes and missteps by LE that have never handled a homicide before. IMO a more uniform and effective approach would be a Federal agency that only investigates homicides . I am sure most victims family would agree, as well as most small town LE agencies.
The FBI was involved very early in this case. Are you saying you'd want to expand the FBI to do all local homicides? That would be an incredible change in recruitment and training (each FBI agent gets a *lot* of training - often coming from a prior LE background outside the bureau). There are wait lists for all this training and new agents are hard to find.
Are you saying every homicide should be investigated by the federal government?
At any rate, the Chief of Police in Moscow, ID has himself graduated the FBI academy and he called in the FBI right away. There are some 40+ FBI people on this case (about twice as many as the local LE staff) and some 15 US Marshals.
The number of steps involved in calling in and then responding to a homicide would prevent the FBI from arriving first. In this case, the roommates first called friends to try and open the doors of the non-responsive roommates. Then, 911 was called and LE/EMT's came. It was a shocking crime scene, certainly. But there's no evidence that local LE screwed up their initial response. And they are still holding the house as a crime scene.
A death certificate is only going to list the very minimum. Most likely the COD and the MOD. IMO.
And I would guess that the actual autopsy report is still under lock and key. It's a crucial part of the ongoing investigation.
So SG's comments are his own, based on viewing a body or bodies, and on the death certificate(s). I'd be very surprised if any of the families have been given the autopsy report at this point in time.
Certainly he could view Kaylee's body, but not MM's.
Although the two families are very close and since SG says he brought two urns to his house, it's possible he was charged with handling funeral arrangements or that both families went to the funeral parlor together. I believe they are from the same hometown and K and M's Instagrams show a longterm close relationship between the two families.
