A Tarrant County jury sentenced a 40-year-old man to life in prison for aggravated robbery on Thursday.
According to officials, Jeremiah Stevenson went to a Valero store last year and demanded money.
Police said Stevenson shot at the clerk and missed before grabbing cash from the register and a pack of cigarettes. He then fled the convenience store.
After his arrest, while Stevenson was being held at the Lon Evans Corrections Center in Fort Worth, he used a fire extinguisher to escape from a 5th-floor window, the Tarrant County Sheriff's Office said.
