This is the best summary I could come up with:

An Ontario man currently in a U.S. jail awaiting sentencing for running a fraudulent allergy testing company was also a key employee in a Canadian DNA laboratory that a CBC News investigation found has a history of producing wrong paternity results.

Arrested in Spain and extradited last November to the U.S., Tsui made millions of dollars offering allergy testing through hair samples that he ultimately tossed in the garbage without analyzing, court records show.

Harvey Tenenbaum, Viaguard's owner, recently told a CBC News producer posing as a potential customer that he knew the laboratory's prenatal paternity tests couldn't be trusted.

Tsui appeared on television representing Viaguard in 2014 when news emerged that the laboratory had found a genetic link between former prime minister John Diefenbaker and George Dryden, his suspected illegitimate son.

Tsui rented a mailbox at an outlet in Hyde Park, N.Y., where his online company received 4,500 pieces of mail weekly, containing mostly hair samples, between September 2018 and February 2019.

"Mr. Tsui deeply regrets his criminal conduct and is in the process of doing as much as he can to rectify his actions, including paying full restitution to his victims before his sentencing," said his New York City lawyer Jeffrey Lichtman.
