A Whitfield County man may be facing a death penalty trial in connection with the brutal slayings of his wife and her father.  49-year-old Adolph "Sonny" Neal was indicted on two counts of malice murder last week.  He was the subject of an intense man hunt after the Dawnville murders were discovered by the couple's nine-year-old child.  Neal was found a week later in a wooded area about 12 miles from his home.  His 27-year-old wife, Jessica, had been stabbed repeatedly.   Her father, 69-year-old Donald Shedd, was beaten to death with a wrench, police say.
