UPDATE: A father and son were killed after falling into a grain bin in northeast Iowa, authorities said in identifying them Friday.
Waverly Fire Chief Dennis Happel identified the two as Rick and Adam Schneider. The men were pulled unconscious from the bin at Schneider's Milling around 2:15 p.m. on Thursday and taken to Waverly Health Center, where they were pronounced dead.
The Schneiders were checking the bin because a small fire had occurred inside on Wednesday and they were making sure it was completely extinguished, KWWL reported.
Happel said the men went into the bin before 1 p.m. and collapsed atop several feet of corn, likely because of a lack of oxygen. He didn't know if they took safety equipment with them.
A worker entered the bin after seeing through an access hatch that the men had collapsed. Firefighters had to cut a hole in the bin to reach them.
Happel said occupational safety and health enforcement officials in Iowa are investigating the accident and were on site Friday.
The men's bodies have been sent to the state medical examiner's office in Ankeny, Happel said.
Schneider Milling is on the east edge of Waverly. KCCI said it is a family-run business owned by Rick Schneider's father.[mqMap key="qLAOyI2U" width="680" height="420" src="http://www.mapquest.com/embed?icid=mqdist_mb_wp&c=qLAOyI2U&maptype=map&zm=13&cr=42.72295642101427,-92.44721592355432&projection=sm&showScale=false"]My New Map[/mqMap]
