An attorney who killed himself in Canada on Monday had leaked insider information while an associate with Sullivan & Cromwell in New York in the 1990s and as a partner in Dorsey & Whitney‘s Toronto office from 2004 to 2008, according to a complaint filed by the Securities and Exchange Commission.

Attorney Gil I. Cornblum, 39, whose body was found below a bridge in Toronto at 7:16 a.m. on Monday, sent his former law school classmate Stanko J. Grmovsek, 40, material, non-public information on some 40 mergers and acquisitions that he learned about while on the job at both law firms. All told, the two men made $10 million on the scheme, according to the SEC.
