Burglars will often use a con to gain entry to your home. The subject will knock on your door and when you answer attempt to play upon your sympathies. The subject will claim to be cold or hungry and in need of your help. When you let the person in and leave the person alone they will take items and leave.
Burglars have also been known to pose as utility employees in an attempt to gain entry to your home. They will claim they need to check your fuse panel or pipes. One subject will ask you to show him where your fuse panel or water meter is located. While you do this the other subjects will go through your house in an attempt to locate valuables that can be carried away. REMEMBER any legitimate utility employee will have a photo ID on his person. IF you are ever in doubt DO NOT let the person into your home and call the utility company they represent to verify their identity and need to be in your home.
