My father in law went to London to visit sil, he has been there many times before. He went out on friday morning and never came back. he is 73 elderly, has had/has a drink problem, has had a stroke and can be confused. My sil only phoned and told my bil yesterday and eventually through a message from Australia we found out this afternoon. Dh's family don't really have good relations and this particular sil has caused us big problems in the past, so we are not sure if she is telling the whole truth. Anyway thats another issue. What I need to know is if anyone has any tips, we have called the police and national missing help line.
