A man who has already been jailed for this role in a massive fraud case said Tuesday he tried to cover up his involvement. Leo Caron made the admission as Atlas Copco trial resumed after a one-week break. Caron, the human resources manager for Atlas Copco Canada in Sudbury at the time of the alleged scandal, spoke about his role in the scheme. Apparently, he was authorizing advances to himself that totaled more than $1.6 million, which was never declared as income. He also asked his colleagues to delete emails implicating him in the fraud scheme. He said he had no choice, but made no admission of guilt. He also discussed purported treatment for cancer that allegedly cost about $40,000; however, Caron admitted he had not had cancer.
