Tulsa Police Officer Jeanne MacKenzie says the 7-year-old girl, Hafsa Hayle, helped her 9-year-old sister escape, and the 9-year-old ran to a nearby house for help. MacKenzie tells the Tulsa World that when authorities arrived, they found an 11-year-old girl in critical condition with stab wounds and the house on fire.

Police believe Ahmad fled with the youngest girl.

An Amber Alert says Ahmad may be driving a black Lexus RX300 SUV with paper tags, a 2011 Ford Escape or a navy blue Ford sedan.
