US police were called to what looked like a woman shot dead in her car, but found a Halloween reveller they described as drunk and passed out in a bloody-looking zombie costume.
The news site, www.al.com, reports a passerby called police on Thursday morning (local time) after seeing the woman slumped over her steering wheel at a traffic light.
Police say officers roused the woman and removed her from the vehicle.
Authorities say she was handcuffed and taken to the city jail on a charge of driving under the influence of alcohol.
A photo of the woman by al.com showed fake blood covering much of her torso as she was apprehended.
