Random Riddle :)

My neighbors think I am a nosey old women, but today I witnessed a murder. I was looking out my window when I saw something through the window of my apartment building opposite mine. A man was in the middle of murdering a women. The strange thing was, after he was finished strangling her, he turned around and our eyes met. It was eerie. Then he pointed at me and kept staring at me for a long time. All the time he was staring at me, his finger kept moving. I called the police a few minutes ago and they told me I have to go to police station and give a statement tomorrow morning. I'm sure they will catch him. I saw his face very clearly
