ST. LOUIS (KMOX) - A 33-year-old woman has received fifteen years in prison for her latest crime: robbing a White Castle restaurant with a water pistol.

St. Louis prosecutors say Michelle White pulled up to the drive-thru window, pulled out a red water gun, and handed an employee a note that said “give me your money or I’ll shoot you.”

When the employee ran into the back room, White climbed through the window and took a cash drawer.

An off-duty St. Louis firefighter saw the whole thing, took down her license plate number, and called police. When police arrived at her home, White climbed onto the roof and jumped, fracturing an arm, a leg and her pelvis. Police found the missing money in her home.

Prosecutors say the mother of three has a criminal history.
