For the second day, ATF investigators managed to go inside the burned shell of the former Younkers Building.
Experts are focusing on the western side of the structure, near the old tea room.
Wednesday’s efforts involved forensic mapping and photography techniques. ATF officials say they only have one chance to do the job right.
“We’ll continue to document the scene,” ATF’s John Ham says. “We only have one shot at this. The building can’t stand in this condition forever. So while we are here we are using the forensic mapping technology, photography and other tools to document what’s here so we have a very precise record of what was here.”
Ham says the wind has been a challenge, but that today it was the calmest it’s been since the start of the investigation.
