As the public inquiry into the Algo Mall collapse in Elliot Lake sets to begin on Monday, there are videos surfacing that show another collapse as the demolition crew tears the building down.

The Ministry of Labour was called in to investigate the incident but says the part of the building collapsed on top of an unmanned excavator, however the videos show someone running out from under the rubble.

The inquiry is expected to last several months and Justice Paul Belanger who will be overseeing it will have a year and a half to release his findings.

Another revelation also finds that the engineer who oversaw the design of the structure, botched so later projects, and as a result he was fined $25-thousand, and stripped of his license.

Two women were killed in the collapse.
