Metropolitan Police have brought in 9/11 specialists to assist the investigation into Grenfell Tower.
At the moment 200 UK officers on the case are faced with shifting 15 tonnes of debris from across the 24 stories of the building.
The organisation's deputy commissioner, Craig Mackey, said the "extraordinary size" of the crime scene had necessitated the recruitment of experts who worked on the scene in the wake of the 2001 terror attack on the Twin Towers.
Giving an update on the case, Mackey called the current operation "one of the most complex" the police had seen.
At least 80 people have either been confirmed dead or remain missing in the wake of the fire which consumed the tower on June 14.
The latest victim was named by Scotland Yard as Majorie Vital.
