A jury convicted Dalton Fletcher on Monday of the September 2010 shooting deaths of the father and mother in their home west of Monroe.
The jury did not believe the teenager was insane at the time he killed the couple, instead believing the prosecution’s argument that Fletcher had been planning the killings for almost two months.
His attorney argued the shootings were the result of persistent and repetitive abuse by the father.
Fletcher shot his parents with a 12-gauge shotgun and threatened to shoot his sister. He put the gun in the trunk of his mother’s car and drive to West Ouachita High later that morning to attend classes.
His sister escaped her bindings and called police.
The trial was moved to Benton because of pre-trial publicity about the case.
