MILWAUKEE — A researcher at the Medical College of Wisconsin is charged with espionage after prosecutors say he stole details of a cancer-fighting compound that he wanted to share with China.

　　Prosecutors say Hua Jun Zhao stole the compound, C-25, and data that led to its development.

　　A federal complaint says investigators found several hundred items related to research into C-25 on Zhao's computer. Authorities found a grant application from Zhao, written in Mandarin, claiming he discovered the compound and seeking Chinese funding to continue research.

　　The 42-year-old Zhao is charged with economic espionage, which carries a maximum 15 years in prison and a $500,000 fine.

　　Public defender Juval Scott didn't immediately return a message Tuesday from The Associated Press. She tells the Milwaukee Journal Sentinel that Zhao is a "talented professional."
