Much of the information given in the above posts is not true. I live very close and watched it happen. The police were there within a very short time period. People can enter our property from many entrances and police were stopping people and redirecting them. The street was closed. As I understand it at the moment, this involved a person with mental problems. Our neighborhood is trying to deal with this senseless tragedy which is the worst thing by far that has ever occurred in this wonderful neigborhood since I moved here 20 years ago. Many people are very upset, including the family of the victims, so please keep that in mind when you make comments.
