 Three wealthy parents including the former chief executives of bond manager Pimco and specialty finance lender Hercules Capital Inc will appear in court on Monday to plead guilty to participating in a vast U.S. college admissions cheating and fraud scheme. Federal prosecutors in Boston allege that ex-Pimco CEO Douglas Hodge, Hercules Capital founder Manuel Henriquez and onetime food manufacturer executive Michelle Janavs paid hundreds of thousands of dollars to have their children admitted to universities as fake athletic recruits.
