A fourth person has died following the Didion Milling explosion in Cambria.
The company said 46-year-old Angel Reyes died Tuesday at the University of Wisconsin Hospital in Madison.
Cambria Village President said many people in this community feel connected to those who have died.
"It's been a shock obviously," said Glenn WIlliams. "The fatalities as far as I know are from the local areas, not from right in Cambria, so it's affected more communities than just are own."
Williams said about 23 fire departments and 10 ambulances responded that evening to assist.
He said there was a debriefing for the public at the Cambria Fire Department Monday night and about 160 people showed up for support and counseling.
The cause of the explosion is part of an ongoing investigation at Didion Milling plant.
"It's actually something we probably won't know for a while the ripple effect of it," Williams said. "It's definitely a shock and our hearts go out to the families involved."
A representative from the crisis communication team for Didion said factory workers have returned to work in waves to help re-establish operations at plant. He said about 1/3 have returned already.
