Yesterday Wednesday, April 29, 2009 at around 9:30am there was a white ('90's buick or chevrolet) park in my driveway and when my daughter left for school made me aware of it and I asked driver what was he doing parked in my driveway and he showed me a private investigator id and badge and stated he was checking some workers doing deliveries in our neighborhood. I found story to be kind of suspicious and afraid went inside my home trying to figure what to do and 5 minutes later I went back out and car was gone. I ran back in the house and got car keys and drove around neighborhood looking for vehicle but did not see it and thought it was kind of suspicious. Well I think that he might have been i thief looking to see if nobody is home to break in. My advise if anybody sees a car in any driveway or in front of any home with driver inside and kind of suspicious call police. And if nobody is home most of the day set your alarm. We must stick together to make our neighborhood a safe place to live in.
