From a BBC report it was one guy who heard the initial report from the rescue team that they were 'checking vital signs' (or something along those lines) and took that to mean (along with quite possibly others) that this ment the men were alive. He then went to spread the news before the confirmation came through that of the 12 there (one body found earlier), 11 were dead and one critical. When the news broke of the multiple fatalities apparent this guy had to be escorted away from the church by police. I really feel sorry for him (and obviously all the families and miners too).
