MILWAUKEE — A researcher accused of stealing a possible cancer-fighting compound from the Medical College of Wisconsin is expected to plead guilty to a reduced computer-related charge.

Hua Jun Zhao was accused of stealing three vials of the compound. Prosecutors say he also stole academic research that he planned to pass off as his own in China.

Zhao initially pleaded not guilty to tampering with a private computer and lying to a federal agent. Court records say he agreed to change his plea at a hearing set for Wednesday.

A plea agreement says Zhao will plead guilty to accessing a computer without authorization, punishable by up to 5 years in prison and a $250,000 fine.

Defense attorney Michelle Jacobs says she expects the hearing will conform to the plea agreement.
