OP: I strongly agree with what you write. The recent past history regarding recognizing homicides in general hasn’t been entirely favourable toward LE.
By not favourable, the OP means that LE's interpretation of some past murders have been plain wrong. In fact, it seems they chose to take the easy route and focus on the KISS principle (which some seem to be suggesting is good enough in this Sherman case as well), which in the end, hindered their ability to produce evidence for the Crown in prosecuting the murderer(s). Had LE instead operated with open minds, collected evidence, and then followed the evidence, it could have saved lives.
I am speaking of the Laura Babcock and Wayne Millard cases specifically. By the time LE figured out they needed evidence because the crimes were not as they initially may have appeared, it was too late to collect evidence - CCTV was recorded over, crimescenes were adulterated, people had lots of time to get stories straight if they felt they needed to, etc. Thankfully in *this* Sherman case, the family hiring their own set of investigators and paying to have second autopsies performed, has, at the very minimum, served the purpose of keeping LE on their toes in this case and performing the due diligence with which the public *assumes* all cases are being treated in the first place.
