Former Purdue student Roy Sun, 25, will spend 90 days behind bars for his role in stealing professors’ passwords and changing his grades. Sun took the stand today and admitted to changing 10 grades over the span of two years while he was a student at Purdue.

Investigators said Sun worked with two friends, Sujay Sharma and Mitsutoshi Shirasaki to break into professors’ offices, bug their computers, steal passwords and then change their grades.

Sun said in the beginning they only stole exams. He said he felt “untouchable” when they got away with changing his grades.

Sun graduated Purdue in 2010. He worked as an engineer for a few years before going to graduate school at Boston University. He was attending school there when he was arrested last spring. Boston University has since expelled Sun.

Sun pleaded guilty in December to two counts of computer tampering and one count of conspiracy to commit computer tampering.

Sharma was sentenced to 18 months probation and 200 hours of community service on Monday.

Shirasaki is believed to be in Japan and is wanted on a warrant.

Sun was also sentenced to 4 years probation after he serves his jail time, 100 hours of community service and the judge ordered that he must pay $330 to Purdue and return transcripts and his diploma from the university.
