"I heard breaking glass - a lot of breaking glass. I thought it was people going crazy in the corridor outside," Ms Martin told the murder trial at the Supreme Court in Brisbane. "But it went on a bit too long. Then I heard the popping of timber and crackling and people's voices and there was this nasty smell of burning plastic." It was at this point that she understood she was listening to people trying to flee a rapidly growing fire, a realisation, she said, which was "a bit surreal".
