Then you would be saving your Dad also. His instincts are in high gear also. I would listen to both of your instincts. Your Dad and you can pull this off. Get together with your Dad and follow him. I have done this before. You just have to be very careful. Don't do it without your Dad. Use two cars if you have to and cell phones to communicate. Stay far away and see where he goes. You can even supply a photo to immigration and just tell them where he is if he goes to someone elses house. I am sure you don't want him picked up at your Mom's but if that is what it takes, I say "do it".
