Do not leave check books unattended. If they are left unattended, immediately check to insure all the checks are still in the book. To give him or her more time to use the checks without the fear of being discovered, a perpetrator may only take a few checks from deep inside the checkbook. You will not notice this has happened until you get to that point in the book or until you get your monthly statement. Remember the checks usually list your name address and phone number. Even if the perpetrator does not use the checks, he or she may use the information on them for other means. They know from observing you, the way you dress, and the car you drive what salary level you are probably in. From the check, they can usually tell if you are single and probably living alone. They can immediately go to your address and take what they need since they know where you are at the time. They may even leave a lookout to watch you and report back your location.
