JUNE 2--A Texas teenager angling for the lead role in a school play is facing charges that she spiked a competing actress's drink with Clorox. Katherine Smith, 18, was arrested this week and hit with a felony rap for tampering with a consumer product (in this case a bottle of Mountain Dew she gave to a 15-year-old rival). According to a Tarrant County arrest warrant, Smith was the understudy of the teen victim in a play called 'Ha.' By dosing the younger actress's Dew, Smith believed that she would take over the play's lead role. The warrant notes that Smith 'had a lot of family coming in from out of town to see the play and watch her perform.' Additionally, Smith's mother believed that her daughter was the play's main character, not an understudy for the February performances at L.D. Bell High School in Hurst. Smith, who used an eye dropper to place bleach in the 20-ounce soda bottle, told a school administrator that she wanted to harm the lead actress 'so she could not perform in the play.' Smith's plot was thwarted when the girl smelled an unusual odor emanating from the Dew. Pictured below in a Tarrant County Sheriff's Office mug shot, Smith faces up to 20 years in prison if convicted of the spiking bid. (4 pages)
