OKLAHOMA CITY --
Investigators said they still haven't determined what caused an Oklahoma City firefighter to collapse and die at the scene of an apartment fire on Wednesday.
Corp. Chris Dill's fellow firefighters said they planned to do whatever they could to help his family through the difficult time.
Oklahoma City Fire Chief Keith Bryant said his wife didn't think that when Dill headed out to fight the fire that it would be the last time she would see him.
"You know it could happen, but when it does, I don't think someone can truly be prepared for that," Bryant said.
Bryant said that when Dill was putting away his equipment, he started to complain about back pain. He said Dill sat down to try to ease the pain and then collapsed moments later.
Julie Dill rushed to the hospital to meet her husband but found his friends and colleagues with tears in their eyes.
"They are very hurt," Bryant said. "But what I've seen so far, they have a great support system of family and friends and they have great support from this department."
The Dills had two young daughters, ages 7 and 5, and both attend Fisher Elementary School in Moore, where Julie Dill works as a teacher.
Thursday, the school's principal went to every classroom and explained what happened.
