A 45-year-old woman named Sandra Froust recently got arrested for robbing a store at gunpoint in West Monroe, Louisiana. And she might have come up with the worst alibi ever . . .

Several people identified her SUV . . . got part of her license plate . . . and the whole thing was caught on a security camera.

So she claimed she lent her SUV and her clothes to a woman who just LOOKED like her. But apparently she couldn’t come up with a name.

And that wasn’t even the worst part. She also claimed that she couldn’t have robbed the store . . . because she’d been hanging out smoking CRACK for the past ten days.

The cops talked to her family, and they confirmed that she DOES smoke a lot of crack. But they also said she hadn’t been home in about a week. So that made her alibi even thinner.

Now she’s facing charges for armed robbery.
