UK police now believe that all the people found inside a container on Wednesday were Chinese nationals, according to the latest update on the investigation’s progress Thursday morning, CNN reported.

“Of these, 38 are believed to be adults, and one is a young adult woman. We previously reported that she may have been a teenager. We have since confirmed that eight of the deceased are women and 31 are men and all are believed to be Chinese nationals,” Essex police said in a statement.

The statement continued that a full coroner’s process must be undertaken for each person to establish a cause of death before the investigation will move on to attempting to identify each individual found in the container.
