Oliver Killeen - Conman and Bigamist

The Man with 14 Wives

The Man with Fourteen Wives

Oliver Killeen

Oliver J. Killeen is a conman and a multiple bigamist. He says of himself: "Oliver Killeen might be some type of name, but really it's just a cover for multiple personalities". He has nearly 200 fraud offences against his name, but his real claim to fame is that he is one of the world's most prolific bigamists.

Killeen sometimes claims to have been born in New York, but the truth is he was born in Castlebar, southern Ireland in 1937. He attended a Christian Brothers School, leaving at the age of seventeen.

Young Oliver headed for London then on to Toronto with his Irish sweetheart, Mary.


Oliver and Mary remained married for almost 20 years and had eight children. Mary died in 1974 after contracting septicaemia, she was 38 years old.

It was only after Mary's death that Killeen began his 30 year career as a fraudster and bigamist. Now, at the age of 68 he still seems to believe that his charm is irresistible to women.

Bigamy is just one of his cons, Killeen's other great ruse was transforming himself from plain Oliver Killeen into the entirely bogus Dr. Killeen, an American psychologist. He set himself up as a relationships and addiction specialist, which is perhaps appropriate given his history with marrying many women and the fact that he is an alcoholic.

Oliver and Mary's Children

Killeen met his last wife, Margaret, in London while she was one of his clients. They married in 1996 and had a daughter soon after. They moved to Ireland hoping the psychotherapy business would really take off. He conned his way onto the radio station TIP FM where the DJ Seamus Martin interviewed him about his new psychological counselling practise.

Killeen had awarded himself a degree in psychology from Berkeley, California and a PHD from Ontario< Canada, In reality, he has never attended university, he felt he didn't need to. He didn't consider psychology as a true science.

Killeen prospered, organising talks and seminars, even producing his relaxation tapes. He wrote hundreds of articles for Irish newspapers, and was, at this point, earning £5,000 per week.

The Relaxation Tape

He told Margaret that all his money was tied up in investments in Canada and persuaded her to take out bank and credit card processing loans to the tune of £80,000. Margaret was not the first wife he had conned in this way, In 1990 he managed to cheat Susan Robertson out of £100,000 in the same way. She is still paying off this debt to this day.

In 2001, his career came to an abrupt end. He was the expert witness in a sex-abuse case when the defence lawyer asked for confirmation of his credentials. The truth was out, all of his qualifications were bogus.

Killeen fled Waterford for London leaving behind many distraught patients. He has never been charged for these deceptions. Killeen had preyed on vulnerable women, all his ex-wives had mental problems of one sort or another.

Some of the wives (those he can remember)

Margaret reported him to the police after receiving a letter from one of his other wives. He was arrested, tried and convicted. He was sentenced to 3 years at Isleworth Crown Court, one of the longest sentences for bigamy in post-war Britain.
