From what I've read about Avonte, I doubt he would change his clothes. If he cannot feed himself, then he likely can't dress himself, either. But, I've wondered also about his toileting skills. I doubt he would seek out restroom facilities on his own. I can't imagine what condition he's in now, if he's still alive. I hope he is still alive and is found soon, but I know the chances are waning.
ETA: I also can't imagine someone with autism hanging out in a noisy place, or a place where a lot of people are around. He would likely be wary of anyone trying to help him. That's why I find it hard to believe that someone is taking care of him. He may stay around temporarily if offered something to eat and drink when he gets hungry and thirsty, but being in an unfamiliar environment he is going to bolt again as he did at school.
