Police in Birmingham, Alabama, made a ghoulish find after responding to a report of a woman who had reportedly been shot and was covered in blood and slumped over the wheel of her car stopped at a traffic light, reports Al.com.

A passerby called 911 on Thursday -- one day after Halloween -- after noticing the woman, who also appeared to be pregnant.  Authorities say when officers arrived, they determined the woman was not shot, but she may very well have downed a few shots at a Halloween party.  Police say she was drunk and still wearing her Halloween costume, which was that of a bloody-pregnant-zombie.

She was not really pregnant -- her "pregnancy" was just part of the costume, according to police.  The woman was arrested and charged with DUI.  She said, "It's all good" before being hauled off by officers.
