My child's father disappeared with my baby? what to do?

[Sarra]

I have sole custody of my newly one year old, from day 1 he wanted nothing to do with our daughter, he told me to get an abortion, he wouldn't be able to be in the child's life etc. When she was born he changed only a little.Well after her birthday party 2 days ago he came over my house to help out with her presents and just to hang out . He went out and bought some liquor, we drank and he clearly got drunk so I let him sleep on the couch, I went to go check on my baby girl who was in her crib (her crib is in my room) sleeping peacefully, I go to bed. I wake up around 5 am to feed her and then we go back to sleep in my bed . I awake at 9 am and she is gone, I look every where around the house and to find he is gone as well. I text and call him , he doesn't text or call me back . I called the police and they are on the hunt for him but he is no where to be found, I'm going crazy I blamed myself I don't know what to do, I want my baby back, why would he do this, what should I do?
