The sentencing of three men convicted of kidnapping and holding the son of a B.C. millionaire businessman has been adjourned until February.

The lawyer for Jose Hernandez told B.C. Supreme Court Justice Arne Silverman she needs time for a psychiatrist to complete a report on her client.

Hernandez and Anh The Nguyen were convicted in October of kidnapping and unlawful confinement of University of British Columbia student Graham McMynn while Sam Van Vu was found guilty of unlawful confinement but acquitted of kidnapping.

Two other young men, including Vu's brother, were acquitted of both charges in the April 2006 abduction of McMynn.

A massive police operation involving hundreds of officers climaxed in McMynn's rescue 10 days later.

His father Robert McMynn was at today's brief hearing and says his main concern is that the three -- who've been in custody since their arrest -- could earn double credit for the time spent in jail before sentencing.

A terrifying ordeal

McMynn spent much of his captivity in terror.

He testified at the kidnappers' B.C. Supreme Court trial that at one point he was threatened with a gun to his head and later his captors talked about cutting off his hand.

He told the court one kidnapper told him they had been hired by another group to grab him but were not responsible for negotiating a ransom.

No ransom demand was ever received, despite a televised plea by McMynn's parents asking to be contacted. Police say it's not clear if there ever was a second group.

The Crown's case against the five accused was largely circumstantial, based on intercepted phone conversations, testimony of associates and DNA tying them to locations were McMynn was held.

But defence lawyers argued that just because their clients had been present at those places did not mean they took an active part in his abduction or confinement.

But Justice Arne Silvermen found there was enough evidence against three of the men -- all in their twenties -- to find them guilty.

McMynn's father, Robert McMynn, who owns a bus-leasing company, said that while police were satisfied with the outcome, he felt all five should have been convicted.

Since his testimony almost a year ago, the kidnap victim has stayed largely out of the spotlight.

After the convictions, McMynn did one television interview in exchange for a $5,000 donation to the Vancouver Police Foundation.
