VANCOUVER - A sentencing hearing is underway for three young men convicted of kidnapping the son of a wealthy Vancouver businessman.

Jose Hernandez and Anh The Nguyen face maximum life sentences for kidnapping and unlawfully confining Graham McMynn, while Sam Van Vu could get up to 10 years for unlawful confinement.

Prosecutor Richard Cairns opened the hearing in B.C. Supreme Court by telling Justice Arne Silverman that there were a number of aggravating elements in the case that should result in `very serious consequences' for the three men convicted of the high-profile abduction.

Two other young men, including Vu's brother, were acquitted in a lengthy trial last year and one youth is has yet to face trial.

McMynn was abducted at gunpoint from his car in April 2006 while he and his fiancee were driving to university.

He spent eight terrifying days in captivity -- sometimes stripped and bound -- before police rescued him in a massive operation involving hundreds of officers.
