This article discusses a 1994 murder case in Poland in which polygraph testing used situational sequencing tests to try to determine who shot the victim, who transported the body or helped transport it, and the role of police officers other than the police officer suspected of being the murderer.
Abstract
The author developed the technique to address cases in which the testing seeks to determine both direct and indirect participation in a crime. The test had 12 questions. The suspect refused to undergo polygraph testing. The testing examined other persons whose roles in the crime were unclear. The polygraph testing in this case confirmed its methodological assumptions and disproved claims of opponents regarding the agitation displayed by innocent persons. The case indicated the difficulties in assessing the role of polygraph examination in particular cases, (e.g., can the results be considered verified or not; are they accurate or not?) the potential of the technique, and the difficulties involved in conducting investigations of crimes committed by police officers.
