The biggest mistake that police departments make according to researchers is assuming that a dead body in water is just an accidental drowning. http://abclocal.go.com/wls/story?section=news/iteam&id=9028337 Not that I am saying that EL's case is homicide, but given the bizarre circumstances; I am appalled at how very little investigation seems to have gone on. Up to 20% of drownings ruled as accidental are actually homicides because LE do not even bother to see it as a potential crime scene because they assume water deaths, in absence of obvious trauma, are accidents. That is 7,000 people a year! They note how bodies are immediately removed from water. In EL's case, they took photos, but I would think that they could have taken water and sediment samples to check for trace evidence. I cannot believe they did not test the particulate in her clothes even just to make the case for their ruling stronger. No fingerprints taken, no search for a ladder, I don't think it was ever treated as a crime scene. In all the video footage and photos of LAFD on the roof, I did not see any sort of tape demarking the scene. This article points out that most LE agencies have fire/arson specialists, and people trained in traffic fatalities, but no specialty for water deaths, and it really does seem to require extra training. Sad that this is not a priority. It also skews stats, so it looks like there are very few homicides involving water and that just reinforces LE's dismissal of drownings as accident.
