A St. Louis woman has been sentenced to 15 years in prison for robbing a White Castle with a toy gun.

Prosecutors said 34-year-old Michelle Faye White squeezed through the drive-up window and robbed the restaurant’s employees. When authorities caught up to her at her apartment, she jumped off the roof as they closed in and she suffered a broken pelvis and arm.

She has a previous conviction for manslaughter for killing a man in 2004 while driving under the influence of cocaine and on a revoked license.
