They were found, yes. But sadly too little for three little baby.
I don't believe that's what us in question though, op was saying people may question whether the outcome would have been different and I have wondered this myself. It's difficult without being accused of being in support of them but I do wonder had the police operation been more covert, could they have prevented them from running and hiding? I think they would have run out if cash at some point, become blaze. Thinking they were "safe" and no one was looking for them. I doubt they would have gone so far underground, so thoroughly unprepared if not for the attention and spotlight on them at that time. I mean no one really knows but they were favouring hotels until the point they knew they were front page news, then panic mode set in.
To clarify I don't defend or condone any if their actions, they are wholly responsible for the death of their daughter and I hope it haunts them every day of their wretched lives. I do think things could have been handled differently.
