When my difficult child is "out and about" on the streets, I always get "I will call you back" it all came back to me when I read your post. It think that statement is enough to know that he has other things that are more important right now than speaking with you and grandma about coming home.
I cant really offer much more about the images etc... I am in the same boat. you are one step ahead of me, yours is already out. Direct him to halfway houses is a very good idea.
