Bootsctr linked to this originally, but notice where they say:
We also have to make sure that no other children are harmed or in danger, Conley said. Any other children in this household are also at risk.
To me, that says they think she was murdered (again, as opposed to her being the daughter of illegal immigrants and died through an accident/health issue).
So if you murdered a child, why would you dispose of the body in a public place? Why not in the water where at least more evidence might wash away? Why not buried or under concrete or in some remote area where she would not be discovered for years or at least months?
Only scenario that would make sense to me, is that a boyfriend of a young mother killed her "accidentally" and mom helped dispose of body, but wanted to leave her somewhere she would be discovered and buried.
As far as the clump of hair in the composite near the ear, my daughter had a similar one when we grew out some of her bangs. It is also possibly a photoshop "error". Not really a mistake, but just where the artist got a bit heavy handed and didn't bother making the hair look as wispy as the other fly-aways. It is also possible she had side-burn hair and it was meant to depict that. Or she simply could have cut it herself, as kids love scissors and even the kid friendly type will cut a small section of hair. I'm not entirely sure that it would have been pronounced enough for many people to notice though, especially if no one has come forward by now anyways.
