Rio de Janeiro state’s government has confirmed 94 deaths from floods and mudslides that swept away homes and cars in the city of Petropolis. But even as families prepared to bury their dead, it was unclear Thursday how many bodies remained trapped in the mud. More than 24 hours after the deadly deluge early Tuesday, survivors were digging to find lost loved ones. Rio de Janeiro’s public prosecutors’ office said in a statement Wednesday night that it had compiled a list of 35 people yet to be located.
