I am just as skeptical of this story as I am of those which contains nooses and swasticas. There are a lot of gullible FReepers here.
You don't think the police can tell the difference between real bruises and make up? If it was make up, she'd be charged with filing a false police report.
Story at Pittsburgh Tribune Review indicates that this was reported to police, and she led them back to the ATM in question. I imagine there will be video from the machine's camera.
