Defense attorneys say a coastal Georgia man charged with murder passed a polygraph test in which he denied killing his father and seven others.
Guy Heinze Jr. is scheduled to stand trial Sept. 23 for the 2009 slayings. His lawyers filed a court motion Tuesday asking a judge to let jurors hear results of Heinze's polygraph test, but only if he's convicted and the trial moves to a sentencing phase.
If convicted, Heinze, 25, faces the death penalty.
The Brunswick News reports Heinze took the test June 14. According to court filings, the polygraph examiner concluded the suspect was "telling the truth" when he denied being the killer.
Polygraph results are rarely admitted as evidence in Georgia, though judges can allow them if both prosecutors and defense attorneys consent.
Attorneys on both sides will begin questioning prospective jurors Aug. 19.
Prosecutors say Heinze bludgeoned the victims with a blunt weapon before he called 911 and sobbed, "My whole family is dead."
