There hasn't been any DOCUMENTED PROOF that Ayla had bruises from when she was with dad. Only the word of the mother/mother's family.
As to Ayla's broken arm - Police said early on they'd looked into it - and that they checked it out and didn't find anything hinky (Tried to find the media links for Ayla but for whatever reason can't seem to find the thread?)
There has been nothing other than rumor and accusations when it comes to Ayla having bruises from dad. Clearly dad HAD been taking her to the doctor (and both ER's and Ortho doctors as usually pretty good about moving on ANY suspicious injury to a child - and at this point - if they thought there MIGHT have been - I feel like LE would know about it by now and that someone would've been stepping up for their 15 mins to talk about this?)
So - until there's PROOF I'm not gonna jump on the band wagon of accusing the dad of being abusive.
