Ward faced two counts of inducing a minor to engage in sexually explicit conduct to produce a visual depiction thereof, two counts of transporting and shipping child pornography, and one count of making false statements to the U.S. State Department.
At the time of the crimes, Ward was an Emeritus Professor of Marketing at the University of Pennsylvania's Wharton School of Business. He is no longer an employee.
Ward was also accused of using his position as an Emeritus Professor at Wharton in his attempt to secure a visa for the boy from the U.S. State Department's Consulate General in Recife, Brazil, to bring the victim to the United States.
In his efforts to bring the boy to the United States, Ward falsely said he knew the boy's family and that they were wealthy, to dispel fears that the boy was poor and would become an illegal immigrant.
Ward is already serving a 15-year federal sentence for importing child pornography.
He could be sentenced to a total of 105 years imprisonment and a fine of up to $1,250,000.
Ward's sentencing is set for February 19, 2009.
