A retired Texas judge and his wife have been found dead from shotgun blasts inside their home, leading to the arrest of their adult son, who police say admitted to gunning down both his parents because he did not want to take a sleeping aid.

Seth Carnes, 45, was arrested Monday night and charged with capital murder in the slayings of former Williamson County Judge Alfred “Burt” Carnes and Susan Carnes, both 74.
