Killer in my House

Hello my name Is Elizabeth McCartney,Me and my children are trapped in a Criminal's basement I have four children their names are : Kimberly,Suzy,Michael,and Jonah I loved those kids with all my heart but the worst part about it is I will never see them again,and here's why lets start from the beginning it was a lovely hot day all my kids were at school I was handling a case at the courthouse, my kids got out of school I was late picking them up they were waiting for me in the car-line with their principal Mr.Smith,when they got in the car I told them they would have to walk to their Grandparents house tomorrow because I have a lot of paperwork to do,so when we got home the kids took their baths and went to sleep I took a bath to I have a window in my bathroom right by the bathtub I had a feeling someone was watching me but I just have a overreactive imagination,I have been like that since I was little girl I guess it's been a little hard on me since my husband three weeks ago
