French forensic investigators have completed their work at the site of a deadly collision between a bus and a truck that occured on Friday.
Construction cranes were seen lifting wreckage of the trailer truck that had not been charred to ash, as the country scrambles for clues into what caused the fatal accident.
The wreckage will be transferred to a laboratory for testing, although the location is still to be revealed.
Meanwhile, DNA tests to identify the forty-three victims- many of whom were burnt alive- continues. Three survivors of the crash are still in intensive care at a hospital in Bordeaux, south of France.
French President Francois Hollande is expected to lead a memorial on Tuesday in the tiny village of Petit-Palais-et-Cornemps, where many of the victims came from.
On Monday, Transport secretary Alain Valides announced that the government would open a crisis group to provide counselling to the victims' families.
