Residents in North Babylon are outraged Tuesday about not being notified of a home invasion that left one man dead.According to police, on December 30 an individual asked 82-year-old Charles Kollmar for directions then left. A short time later, when Kollmar was walking down a hallway in his house he noticed that some items were askew and was then struck from behind. Kollmar died 10 days later from his injuries and now police are investigating the incident as a homicide. Neighbors, however, want to know what took so long. Police told News 12 Long Island that they made a mistake in the Kollmar case saying they should've warned the public sooner. Neighbors say that's too little, too late.Police have also confirmed at least two other recent home invasions. One took place on January 8 in North Bay Shore and the other in Miller Place on December 17. Police say in both cases, the attacks did not appear to be random or a threat to the immediate community.
