This was the lead story on most of the TV stations in the area tonight: http://www.wltx.com/news/story.aspx?storyid=67437&catid=2 For the non-Americans who are puzzled by the circumstances: on October 31, Halloween (All Hallows Eve), children dress up in costumes and go from door to door begging for (usually) candy with the expression "trick or treat". That is, "if you don't treat us (to candy), we'll trick you" (with some minor vandalism). I did it myself when I was a child many years ago. Back then, we did it in small groups on our own. Nowadays, parents usually accompany their children out of fear for their safety.
