I sure hope you're right about LE knowing who did this and where they are. And don't worry about scaring me any more than I already am. I'm not sure it's possible. I am writing this in my bedroom with my kids in bed between me and my husband. Yes, I am over-the-top.
I feel so bad for you! I was wondering if you slept with your kids right next to during these times. I know I would!
I think that LE knows who the perp is. Can you just imagine them having made a public announcement that neighborhood is in no danger, if something more were to happen, the liability? So even though nobody has been arrested for this murder, they much have someone they feel sure about. And they will keep him/her/them under surveillance.
However, much as I believe what I am saying, I would sleep next to my kids until someone is actually arrested.
