Zheng Lu, 20, is the last of four students originally charged with forcing Yiran Liu to clean the floor of a Southern California ice cream parlor with her bare hands and then taking Liu to a nearby park where she was forcibly striped, kicked, slapped, forced to eat her own hair, and burned with cigarettes, according to the Los Angeles Times.

In January, the three other students — Yunyao "Helen" Zhai, Yuhan "Coco" Yang, and Xinlei "John" Zhang — entered pleas of no contest to charges of kidnapping and assault, the Los Angeles District Attorney's office told NBC News, as part of a plea deal to avoid torture charges, which carry a life sentence in the state of California. Two of the students also admitted to personally inflicting "great bodily injury during the comission of the crime." The three are currently serving prison terms of between six and 13 years.

Lu originally faced charges of kidnapping, assault, and torture.
