this fire slowing down. do we have any answers, evan? >> reporter: there is still questions to be answered here at this roadhouse. one of the biggest questions is how many people were in this house and why they were in this house. this is a house owned by the housing authority here in diff philadelphia. 26 people were inside. there were eight in the first apartment and 18 in the second apartment. two apartments, 26 people in all, and the housing authority say they're still trying to figure out why there were that many people in the building and saying that may have been too high. they're looking at how much damage was done. what we're learning so far is there were six smoke detectors that we know of and four of them were not operable. you can imagine what a situation that is. a crowded house, small r row house. fire breaks out, maybe with no warning. i can tell you on scene, you can smell what this fire was like.
