A forensic analysis reveals anonymous emails sent to members of the U of I academic senate conference came from Lisa Troyer's computer. Troyer was the chief of staff for university President Michael Hogan at the time the emails were sent. The emails attempted to sway members of the conference's opinions on controversial enrollment management issues. An outside agency determined no evidence that Troyer's computer had been hacked. Officials say the laptop computer was in Troyer's possession when the emails were drafted and sent. There is no evidence that Hogan knew about the emails. Troyer resigned her position as chief of staff on January Fourth but maintains her faculty position as a tenured professor. Troyer maintains that she didn't write, or send, the emails.
