Previous Cases

Below are some examples of previous cases that have involved the assistance of Australian Polygraph Services. Individual names and identities have been removed.

Case One

A husband and wife had both suspected each other of engaging in several sexual relationships with other people since they got married. An appointment was arranged for both parties to attend our offices for testing. The wife past the polygraph test whilst her husband failed and subsequently admitted to having sexual intercourse with two other women unknown to his wife.

Case Two

In the recent McDonalds McScratch & Win competition throughout Australia a number of customers claimed prizes consisting of overseas holidays, cars and expensive electronic products. Contestants had to match tickets with a monopoly board to gain their prizes. When a large number of contestants won prizes it was alleged that the winning contestants had used the previous years tickets to complete the winning entries. A Current Affair requested the services of Steven Van Aperen from Australian Polygraph Services to conduct polygraph testing on three of the winning contestants to verify that they had not used the previous year’s coupons. All three contestants passed their respective polygraph tests.

Case Three

A prominent businessman had been accused of sexually molesting his 5 year old daughter. Police had formally interviewed the man but there was no corroborative scientific or medical evidence to support the allegation. As a result no criminal charges had been laid. During the investigation the man was subjected to various rumours about his alleged conduct. These allegations eventually led to the collapse of his business and the breakdown of his eight year marriage. The businessman vehemently denied any involvement and requested the services of Australian Polygraph Services to conduct a polygraph test to show his innocence. The man passed the test relating to each allegation.

Case Four

A female in a successful 26 year marriage had been accused by a work colleague of having a sexual relationship with another man. She went to great lengths to convince her husband that the rumours were false and without substance. In an effort to prove her innocence she requested that a polygraph test be conducted by Australian Polygraph Services. She passed the polygraph test and then circulated the report to put the rumour to rest. Several months after the polygraph test a work colleague subsequently admitted that she made up the rumour to discredit the woman and prevent her from obtaining a managerial position within the same company.

Case Five

In one case a company cheque had been fraudulently altered. Scientific document examination failed to identify the author of the changes or any fingerprints on the cheque. Australian Polygraph Services was asked to conducted a polygraph test on one staff member who subsequently failed. The employee admitted that he had made the erasures and alterations to the cheque as a result of a gambling addiction.

Case Six

A male had asked to be polygraph tested in relation to an allegation that he was maintaining an affair outside his marriage. When the man was told of his deceptive results he offered a $5,000.00 bribe for a favourable result and report. When this was refused he admitted to having had four affairs since his marriage, one of which was with his former sister in law.

Case Seven

A concerned mother contacted Australian Polygraph Services believing that her 14 year old son was using and selling illegal drugs. The boy’s mother had found large amounts of cash hidden throughout her son’s bedroom. When confronted by his mother the boy denied that he was using or selling drugs. When polygraph tested the boy passed the polygraph test about using or selling drugs. When questioned as to where he was obtaining the money the boy admitted that he was committing burglaries with a friend and then selling the stolen goods.

Case Eight

A family member had been accused of stealing approximately $30,000.00 in cash from a secret location within the family home.

Until the polygraph testing process the company had expended approximately $1.2 million dollars investigating the case.
