Fingerprint analysis of a body part found in the aftermath of the Bismark House mill fire in Oldham revealed that it belonged to Uoc Van Nguyen, one of four Vietnamese reported missing in July.
A DNA analysis is underway to confirm the victim’s identity, police said.
Detective Superintendent Lewis Hughes of the Greater Manchester Police's Major Incident Team said an investigation was underway to figure out why Uoc and others were present at the mill during the fire.
The fire broke out early morning on May 7 and it took four days to extinguish it. At that time, police believed there was no one inside.
However, on July 21, local police received a call saying four Vietnamese nationals were missing and they might have been caught in the fire. The four were later identified as Cuong Van Chu, 39, Uoc Van Nguyen, 31, Duong Van Nguyen, 29 and Nam Thanh Le, 21.
Demolition workers have so far found three bodies at the mill. The first one was found on July 23, and the others were found on July 27 and August 4, U.K. media reported.
