She was part of the International Criminal Tribunal for the former Yugoslavia forensic team who helped uncover the 1995 atrocity.

"I was just doing a job, so it’s not up to me to be a judge.

"It sends a message out to other leaders that certain things are unacceptable to do."

It brought experience and a camaraderie the kind of which is found in such adversity. "I found a lot of great friends through the process.

"It enabled me to find out that I can deal with things that I’d never have thought I could deal with."
