Trinh was charged with giving unauthorized aid in connection with placing programming code in an accessible area of the Internet. Roth was charged with seeking unauthorized aid.
As of press time, the hearing had not reached a conclusion. The outcome can be found online at www.unc.edu/dth.
Adrienne Bryant, Roth's defense counsel, said Coggins had encouraged groupwork and that Roth did not knowingly violate the Honor Code. "Though she had experience with computer programming, she found herself in need of assistance."
During his testimony, Coggins confirmed that he encouraged groupwork but said he clearly and repeatedly told students to work on graded assignments individually. "I told them, `Yes, you may work in groups, but you may not use them in assignments that are graded,'" he said.

And a number of professors came to the hearing to show their support.
Sanjoy Baruah, a computer science professor, said many faculty members in the department, including department Chairman Stephen Weiss, were sympathetic to the charged students. "It was a very atypical course," Baruah said. "I find it hard to believe many of these students would be dishonest in any way."
