SF Gate, a 74 year-old woman has been arrested in Boise for pouring mayonnaise in the county library's book drop.
Joy L. Cassidy is "a person of interest in at least 10 other condiment-related crimes."
For the past year, library employees have reported finding books in the drop box covered in corn syrup and ketchup.
"Cassidy was released from jail and faces a misdemeanor charge of malicious injury to property."
