Georgia polygraph operator Ken Blackstone has pleaded guilty to a single count of perjury, a felony punishable by one to ten years’ imprisonment and a fine of up to $1,000 under Georgia state law. Blackstone committed perjury by falsely claiming during a court hearing that another polygraph examiner, Charles Slupski, had reviewed the charts of a polygraph examination that Blackstone conducted on Guy Heinze Jr., who was charged with, and has since been convicted for, eight murders and one attempted murder. Blackstone was sentenced to five years’ probation and a $1,000 fine.

BRUNSWICK | A polygraph examiner pleaded guilty to perjury Friday for testifying falsely under oath in the Guy Heinze Jr. murder case.

Kenneth Blackstone, 63, of Stone Mountain pleaded guilty Friday to a single count of perjury over his testimony on July 18, 2013, in a motions hearing in Heinze’s case, District Attorney Jackie Johnson said in a release.

Superior Court Judge Roger Lane accepted Blackstone’s plea under Georgia’s First Offender Act, sentenced him to five years to be served on probation and ordered him to pay a $1,000 fine, Johnson said.

Lane also banished Blackstone from the 5-county Brunswick Judicial Circuit and ordered him not to testify in any criminal proceedings in court for two years, Johnson said.

In the motions hearing, Blackstone said he had administered a polygraph to Heinze in which Heinze said he had not killed his father, Guy Heinze Sr., his father’s friend, Russell Toler Sr., Toler’s four children and sister and the boyfriend of Toler’s eldest daughter. It was Heinze Jr. who made the 911 call on Aug. 29, 2009 in which he told an operator he had come home to find his whole family “beat to death.”

One person survived the beating. Byron Jimerson Jr., the then 3-year-old son of Chrissy Toler recovered from a severe head injury.

Blackstone, who was hired by Heinze’s defense team, testified that the test indicated the Heinze was not being deceptive when he said he had not killed the eight victims.

When Assistant District Attorney John B. Johnson III questioned Blackstone about his methods, Blackstone said he had sent the charts from the polygraph exam to Charles “Chuck” Slupski, an independent expert in polygraph examination methods. The state had its own expert, retired Georgia Bureau of Investigation special agent Jerry Rowe who told prosecutors that Slupski had been out of the country at the time and said he had not spoken with Blackstone about the Heinze examination.

Confronted with Slupski’s statement, Blackstone said something to the effect he had been caught.

Polygraph exams are not admissible as evidence but Heinze’s lawyers had intended to use the results as mitigation during sentencing if Heinze had been found guilty later. The defense withdrew the motion and a Glynn County grand jury later indicted Blackstone for perjury.

Heinze was found guilty in November of all eight murders and the attempted murder of Byron Jimerson and is serving life in prison.
