Six people have been found guilty in a Vancouver court in connection with the 2006 kidnapping of three people, including a convicted drug trafficker, that ended in a ransom worth more than $1 million.

Peter Li, his then-girlfriend Jennifer Pan and Li's friend Xiao Cheng were kidnapped in Burnaby in February 2006 and held for almost a month at a house in nearby Richmond, where they were beaten and tortured.

The trio were only released when Li and his family paid as much as $1.3 million in ransom money in Vancouver, Toronto and China and promised more cash to protect Li and his family.

Yat Fung Albert Tse, Viet Bac Nguyen, Nhan Trong Ly, Daniel Luis Soux, Huong Dac Doan and Myles Alexander Vandrick have each been found guilty of various charges related to the kidnapping.

The judge in the case rejected the defence's argument that Li orchestrated his own kidnapping and then colluded with Pan and Cheng to use the accused as scapegoats.

The six men will be sentenced at a later date, while Li is currently in prison after he was convicted in a massive drug trafficking investigation.
