EL SEGUNDO (AP) — An employee of a gourmet popcorn company who took an executive hostage at gunpoint has been sentenced to 20 years in prison.

Los Angeles County prosecutors say 23-year-old Leonora Banuelos was sentenced Monday for the April 2013 attack at a distribution center for Popcornopolis in the Los Angeles suburb of El Segundo.

Prosecutors say Banuelos was distraught over a failed relationship with a co-worker and was looking for that employee when she entered the building. She couldn’t find him and instead took the company’s chief financial officer hostage.

She surrendered after a three-hour standoff without harming the executive.
