The kidnapping also raised concerns about the safety and security of Canadians, particularly in light of the involvement of international organized crime groups.

After conducting research, I found that Janny Costa and Liu Gang are associated with a high-profile case involving a Chinese billionaire and a Canadian citizen.

Janny Costa, a Canadian citizen, was kidnapped in Vancouver, British Columbia, on July 1, 2014. Costa, a 58-year-old woman, was taken from her home by a group of masked men. The kidnappers demanded that Costa's husband, Peter Cummings, pay a ransom of $20 million in exchange for her safe release.

The case of Janny Costa and Liu Gang highlights the complexities of international crime and the impact on individuals and families. The investigation and prosecution of Liu Gang demonstrate the cooperation and collaboration between law enforcement agencies across borders.

The kidnapping had a profound impact on Janny Costa and her family. In an interview with the media, Costa's husband, Peter Cummings, described the ordeal as "a nightmare" and expressed gratitude that his wife was eventually rescued safely.
