I love to hear that there are still honest people in the world-good for you. Another thing you can do is contact the camera maker and based on the serial number if that person registered they can track down the owner.
Lets all take this as a lesson I read about years ago-print your name address and phone number on a piece of paper and then take a picture of it(I am assuming most people are digital) if your camera should get lost hopefully the person will review the pictures and see your info.
