Holly, he just moved into the care home to live with his wife who needed care; he himself is fine and free to come and go as he pleases (or so I read in one report).
However, the staff were right to be concerned when he didn't return - the same as family would be concerned if he hadn't come home. He had told his wife what he was up to but thought he would be stopped if he told anyone else. To be fair to the staff, they had tried to get him onto a RBL official trip but had not managed to do so. Some reports were rather embellished, I think!
However, to described him as 'wilful' was rather ridiculous, I thought. 'Determined' yes, but wilful makes him sound like a naughty child.
