We live in a very quite suburban residential neighborhood. I have never heard of a burglary or any other crimes in the neighborhood. Last night my wife and I went to bed around midnight. We were awakened around 3:00 AM by someone knocking on our front very hard. We both wondered why someone would be at out door at that time on night without calling us first. We looked out the windows and peep hole but saw nothing. I told Rose to call 911 while I searched through the rest of the house. As she was calling the police we saw a patrol car slowly going down the road with the spot light shinning around the area. He went on by but within a minute of the time of our 911 call two police cars pulled up out front and 3 uniformed officers and a plain clothes cop got out of the vehicles shining their flashlights on our property. I opened the front door and when down the porch steps to meet them. As I got to the bottom step an officer shined his flashlight on the steps and said "Watch out where you step, there's blood on the steps." He had noticed that I was bare footed. I don't think I stepped in any. My wife told the cops that we have several buildings in the bake of the house that were not locked. They did a quick search and found nothing. Then they looked around some of our nearby neighbor's yards and continued their search around the neighborhood. After they left we took a closer look at our front door and porch. There was fresh blood all over the door from the door knocker down. It had even puddled up where it ran down the door onto the threshold. I'll put on some protective gloves and clean it up today. Needless to say we did not get much sleep after that. We may never know what the guy did or if they apprehended him latter but I know I’ll never forget the whole situation. BTW, I forgot to mention that after the cops searched our property outside they were shinning flashlights on the front grill and hood of one of the patrol cars which leads me to believe that they were trying to arrest the guy nearby and a struggle took place and the guy escaped. One of the cops said they were looking for him for ten minutes before we called 911.
