It's possible she actually did kill herself. And the cops did nothing more than ignore the paperwork saying "she's on meds and admitted suicidal".
That mugshot looks like a half-assed attempt to cover this error. They know they're looking at lawsuits, prosecution, etc for missing the paperwork. Writing over dates, creating a 2nd set of documents, and then a mugshot where gravity pulls face, the floor as a background, deadpan look, hair falling backwards, and wearing her jail clothes already...
Seriously fishy pic. IMO, this is an example of a cover-up being worse than the crime (neglect on paperwork). And of course, the police lose ALL credibility when they do this. And of course, people will defend them with "they didn't kill her, they only faked a pic, what's the big deal?" because they don't like the dead person here. But if it was their parent/ child/ themselves that was posed dead in a mugshot, there'd be outrage.
I don't concern with the characteristics of the victim - my concern is with police abusing their power (IF this is the case with a faked mugshot here). If the mugshot is real, they should be shouting it from the roof top. This looks like a very sloppy 2am cover-up job here... down to lowering brightness on her early pics so nobody can see details... shady as fcck.
