§22-1005.
   
   If, after his delivery to the warden for execution, there is good
   reason to believe that a defendant under judgment of death has become
   insane, the warden must call such fact to the attention of the
   district attorney of the county in which the prison is situated, whose
   duty is to immediately file in the district or superior court of such
   county a petition stating the conviction and judgment and the fact
   that the defendant is believed to be insane and asking that the
   question of his sanity be inquired into. Thereupon, the court must at
   once cause to be summoned and impaneled from the regular jury list a
   jury of twelve persons to hear such inquiry.
