Kampfer told KTAB News' Tiffany Tatro the administrator of the polygraph test did not release results to anyone that was administered the test.
During Thursday night's "Nancy Grace" epsidoe on HLN, Dunn said she was told her boyfriend Shawn Adkins failed a polygraph test prior to receiving the test herself. Dunn says after learning the news, she failed her test.
An expert on Grace's panel said a polygraph test administrator should never do that and revealing information of that nature could cause someone to fail a test.
On Thursday evening, KRBC's Tim Johnston spoke with area polygraph expert Mike Gougler about whether revealing information about who passed or failed a test is commonplace. Gougler says everyone who takes a polygraph is typically told afterwards if they passed or failed, so that's not unusual.
Gougler is not directly involved with this search, and could not speak about the case specifically, but in his experience he says these type of tests can really aid in the investigation.
"When they start running polygraphs early on, they're trying to eliminate people so they can focus their efforts on the most important factor, and that's the safe recovery of the individual that has disappeared."
