Katie McVoy was a member of the WICKED and a friend of Chancellor John Michael, but is primarily the main instigator of VC321xb47 virus, also known as The Flare, that she initially describes as "perfect for their needs", that is to say limit the number of human beings on Earth to preserve resources after the Sun Flares. She only appears during an exchange of emails with the current chancellor in The Maze Runner Files where she confessed to have the virus too and decides to commit suicide so as not contaminating anyone else.
