ELLIOT LAKE, ON - Rachel Rivet, an employee at the downstairs lottery booth in the Algo Centre Mall, is still awaiting word about her co-worker, one of 30 people still missing after the roof of the mall crashed through two floors below, killing at least one person Saturday.

"I hope she's found soon," Rivet said, standing nervously outside the mall as rescue crews continue to dig desperately through the concrete rubble within. "I've been online, asking people to pray. It's been hard. Very hard. I saw her that morning before we started work. I just thank God that not more people are missing or injured."

Rivet pulled away from the interview briefly, eager to hug a man in the crowd she thought to be missing.

"Stan. Oh, my God. You're OK," she said, wrapping the man in her arms.

John Quinte, owner of Hungry Jacks in the mall, was another in the crowd who spent Monday outside the mall, anxiously spotting people, relieved to see them safe.

His wife was one of the 22 injured and taken to hospital after crawling out of the debris.

"(Debris) blew into the restaurant. People were running for the food court," he said, adding he left the same area 20 minutes before the collapse.

A memorial of flowers and candles has been set up outside the ring of yellow tape that circles the mall.
