SOUIX FALLS, S.D. (AP) — One of the first responders who helped rescue a young woman from a building collapse in Sioux Falls that killed a construction worker said he thought of his daughters as he held her hand under the rubble. Sioux Falls firefighter Dustin Luebke held Fodness' hand as crews used small tools to carefully cut through the mattress that cushioned her from the collapsed ceiling above. Once trapped under the rubble, Fodness called her mother, who arrived at the scene immediately. The same could not be said of former marine and construction worker Ethan McMahon, 24, who was killed in the incident.
