The Chinese woman accused in a conspiracy to steal patented corn seeds from Iowa fields has been denied from leaving the United States to visit family members in China, the Des Moines Register reported.

Attorneys for Mo Yun had asked a judge to allow Mo to return to China to see her two grandchildren and an elderly parent in December. But U.S. Magistrate Judge Celeste Bremer ruled that Mo is too much of a “flight risk” to be allowed to leave the country before her trial.

Mo and seven other Chinese citizens have been indicted in a conspiracy to steal corn seeds from DuPont Pioneer, Monsanto and LG Seeds. Mo is accused of participating in the plot from 2007 through 2008, according to the indictment. It has been reported that she worked with her brother to determine which seeds to steal.

A new trial date is in the process of being set as of Dec. 16. If Mo is convicted, she will face up to 10 years in prison.
