A Stephens County jury will hear opening statements Tuesday in the trial against Miles Bench, 23, following a week of jury selection.
Bench is charged with first-degree murder in the death of 16-year-old Braylee Henry of Velma.
Prosecutors claim Bench worked at the Tee Pee Tom convenience store and killed Henry on June 6, 2012 when she came into the store to pay for gas. Bench was later arrested while driving Henry's car. Her body was found in a pasture in Velma after the murder.
Prosecutors are seeking the death penalty in this case.
The defense previously requested the court look into Bench's competency, and in April 2014, a Stephens County jury found he is fit to stand trial.
The trial is expected to last a couple of weeks.
