Colonel Mustard in the Library?

A 74-year-old woman in Boise, Idaho has been busted for pouring condiments into the book drop box of her local library. From the AP story:

Police said a 74-year-old woman arrested after pouring mayonnaise in the Ada County library's book drop box is a person of interest in a yearlong spree of condiment-related crimes of the same sort. The woman was arrested Sunday at the library, moments after police said she pulled through the outside drive-through and dumped an open jar of mayonnaise in the box designated for reading materials.

The woman was released from the county jail and faces a misdemeanor charge of malicious injury to property. Police did not disclose a motive.

Boise police said the woman is under investigation for at least 10 similar cases of vandalism since May 2009. Library employees have reported finding books in the drop box covered in corn syrup and ketchup.

I'm glad the police were finally able to ketchup to her.
