ELLIOT LAKE, Ontario (AP) -- Rescue crews began dismantling a partially collapsed mall late Tuesday night in this northern Ontario city in an effort to rescue victims despite fading hopes of finding anyone alive.
Officials used heavy equipment to clear a path from outside the building to resume rescue efforts stalled over fears the unstable structure could further collapse, leaving rescuers trapped inside the mall.
Rescuers detected breathing inside the rubble early Monday, but authorities enraged local residents when they called off work later that day. One death was confirmed after part of the mall's roof collapsed Saturday afternoon, and another person is known to be still inside.
Bill Neadles, a spokesman for the Heavy Urban Search and Rescue team, said the building was not secure enough to send rescue teams back in at this point but said some heavy machinery from a private company would be employed.
Dan Hefky, the province's community safety commissioner, had said a giant robotic arm would drop into the building and topple a precariously balanced escalator that has prevented rescuers from going inside, but the robotic arm was unable to reach the unstable escalator late Tuesday. Officials moved on to shearing off the front of the mall so they can make a path. Rescue workers are on standby.
"If that's deemed safe our people will enter and deal with both of the victims that are in there," Neadles said.
Residents watched tensely as the robotic arm dismantled the facade of a mall .While some residents cheered, others expressed concern that tearing chunks from the building might jeopardize the safety of anyone clinging to life within the rubble. Many were happy that officials resumed operations more than 24 hours after they halted it, but many are questioning the delay and wondering how officials could possibly halt the operation when they had signs of life mere hours before.
Neadles earlier confirmed that one of those people is dead. The other has been trapped for more than 80 hours and had not had any contact since the rescue team from the building Monday afternoon.
Neadles said a doctor told them Monday, after they shut down the operation, that there was only a remote chance the person is still alive.
"He was of the opinion that it was probably a very slim possibility," Neadles said.
Neadles said a canine search would be conducted if and when the engineer allows them in the building to see if there are any other victims.
Canadian Prime Minister Stephen Harper offered to send in the military to help with the rescue effort. Harper's spokesman Andrew MacDougall said that the federal government is still trying to determine how best to help.
MacDougall said Ontario Premier Dalton McGuinty called Harper on Monday night to inquire about bringing in the military to help.
McGuinty said he wanted to explore the slim odds of a rescue, but said it was a very risky operation.
"It's not unlike a house of cards. It might be if you pull away from this wall in an effort to get access to someone who is trapped in there it may cause other things to move and other things to tumble and to crumble," he said.
A larger crane and robotics normally used in mining disasters will be employed, McGuinty said.
Dozens of residents of the former mining hub had protested in front of city hall after the decision to halt rescue efforts, saying abandoning trapped comrades would be unthinkable in miners' culture. "Rescue missions never end, save our families, save our friends," they chanted, and some suggested that volunteer mine workers should take up the rescue effort themselves.
Among those hardest hit by Monday's decision to call off the rescue mission was Rejean Aylwin, who said he believed his daughter Lucie Aylwin was inside.
"They just gave up," Aylwin said on Monday. "It doesn't make sense. You can't give up. You've got to keep going until you find them."
Aylwin said he worked in a mine for 35 years and that the culture among miners was to never leave someone to perish underground.
On Tuesday morning, at least 70 local residents had volunteered to assist with the renewed rescue effort.
Rhonda Bear, the mall's manager, said the mall's owners were pleading with officials to continue the search and had lawyers who would try for a court injunction against the decision to stop the rescue.
Neadles said crews had used a remote device called the life detector to determine that a person was breathing as of 4 a.m. Monday. He said that person is the same person they heard tapping from on Sunday.
He said the dead person is the same one whose hand and foot were visible in images captured by a remote camera on Sunday.
At least 22 people suffered minor injuries in the collapse at the Algo Centre Mall in Elliot Lake when a portion of the roof that serves as a parking area crumbled into an area near the mall's food court.
Ontario Provincial Police Insp. Percy Jollymore said officers are still trying to determine how many others are missing. A list of names submitted by citizens has been fluctuating dramatically since the accident, he said, but two names have remained constant.
