Nosy Neighbor

The other day I came home to see my neighbors fighting. I was mostly concerned with getting my family in the house without hearing spicy words so I didn't hear what they were fighting about. About a half hour later I hear two loud bangs. I didn't think much of it because we have neighborhood kids who play with fireworks and stuff. Then my imagination started getting the better of me and I decided to just spy on the neighbors a little. I see the husband pacing in and out of the kitchen and constantly looking at the floor. I can only see his shoulders and up so I don't know what is on the floor. I decide to call Tony. He tells me to call the police. I don't want to make a false accusation especially about MURDER and all. So I call up my friend Ellen to see what she says. She says to just call the police. So while I was on the phone with the two of them, I was still spying. I see a friend of his pull up. Then I see them leave with flashlights. I didn't see what they did between these two events because I was looking up the non-emergency number online. I looked up the non-emergency number because I'm still chicken of being wrong. I know, stupid right. By now it's like an hour after the bangs were heard. Here's my conversation with the officer.
Me: Hi I'm calling about something that sounded like gun shots.
Off.: In the Superior, Huron area?
Me: Yes. Do you know what caused the shots?
Off.: No, we do not ma'am.
Me: Well my neighbors were fighting tonight, and I'm worried that he might have shot her.
Off.: The police already have a suspect ma'am, thanks for calling. Bye.
Me: Bye.

Okay, so I felt a little better that my neighbor probably didn't kill his wife but I have to keep watching his house. So I see him and his friend get back. The neighbor shakes his friends hand on the back steps and the friend leaves. Then the neighbor goes in his house and looks out his window right at my house. I jump back from the window and take a deep breath. That night I slept on the couch with both phones beside me and a bat hidden above the door frame. Nothing happened. Yesterday I had almost forget about the whole thing. Then a random thought pops into my head. What if he didn't shoot her? What if he just murdered her? So I've been watching to see if the neighbor lady is still alive, but I haven't seen her yet. Today will be the fourth day.
I also forgot to add in another little bit of history. My neighbors are fairly new. They moved in about two months ago. Their grandchildren are living with them. One of the grandson's told my sons that they have to live with their grandparents because their mom stabbed their dad to death and she's in prison. I don't know if it's true but what if it is? What if the family has a rage problem. I'll keep watching the house for now and I'll keep the doors locked and the phones close. I sure do hope I'm wrong.
