- Notice to the Public Regarding Distraction or Ruse Burglaries - posted 09/27/12
Distraction burglary is a crime in which elderly persons are often the targets. The perpetrator seeks to draw a resident out of the house on a pretext. This could be having the resident take them to the back yard because they need to test the water, or check on a broken pipe in a neighboring house, or to check the electrical power lines. They might just take the resident to the kitchen to test the water.
