SIERRA VISTA, Ariz. —  A Sierra Vista man is accused of lacing a drink he purchased for his ex-girlfriend at a movie theater snack bar with bleach.

Sierra Vista police were called Monday afternoon to the movie theater at the Mall at Sierra Vista after a moviegoer became sick after consuming a beverage.

Police say employees located the drink cup and smelled a distinct odor of bleach in the cup.

The woman was treated at a hospital for burning and blistering in her throat and then released.

An investigation led to police arresting 20-year-old Shawn Ryan Kellerman Tuesday for investigation of aggravated assault.

Kellerman is accused of taking his ex-girlfriend to the movie, purchasing the drink for her and pouring bleach into it.
