Others in that staircase survived the collapse, but could not escape. Mike Warchola, the fire captain on his last day of work, radioed from the rubble that he was around the 12th floor, although the staircase no longer went that high. It is likely that he was among the group that had stopped to help Judith Reese, the woman with asthma from Frank De Martini’s office. None of them made it out. In all, 2,753 people were killed at the trade center.
