Graham McMynn negotiated for his own release with his captors, offering sums between $100,000 and $1 million as he was held, duct-taped in a closet, the young man testified Tuesday.

But a formal ransom demand was never made, leaving the public -- and his grieving family -- in the dark as to why McMynn had been snatched in broad daylight from his car on the way to school.

Instead, the men told them they were professional kidnappers, and they had done this before. They were ordered to get the guy who drove the blue Volkswagen Golf and lived in the house with the Ferrari.

McMynn said he was surprised they knew about the Ferrari because it was kept in the garage.

Mid-way through his captivity, the 23-year-old's parents dropped off a video plea for the kidnappers to communicate.

"Graham, please call us," said his father on the tape. "Graham, call us on line two. You know the number."

When his captors saw the video, McMynn said the men holding him asked, "What's the number for line two?" They never copied it down.

They also wanted to know how much cash his family could pay.

During the ordeal, the men holding kidnapped Graham McMynn threatened to chop off his hand, McMynn testified.

He had already had his eyes duct-taped shut, his family threatened, and been moved from house to house in an attempt to evade police.

But that was when one kidnapper told him that he would cut off his hand. Then, the kidnapper laughed, said McMynn.

Then 23, the son of a wealthy Vancouver businessman was kidnapped on April 4, 2006, and held for eight days before he was rescued in a massive police sting.

On trial for the captivity are Anh The Nguyen, Van Van Vu, Joshua Ponicappo, Jose Hernandez and Sam Taun Vu, aged 19 to 22 years old at the time of the kidnapping.

Each are on trial for one count of kidnapping and one count of unlawful confinement.
