Ten teenagers were among 39 people found dead in a refrigerated trailer in Essex last month, police confirmed.
Essex police released Friday the names of 31 men and eight women whose bodies were found in an industrial park in Grays on October 23, after confirming on Thursday that they were all Vietnamese citizens.
The two youngest were only 15 years old and the oldest was 44 years old.
Anna Bui Thi Nhung, 19, was among 10 teenagers in the truck trailer
The DNA of families who believed their relatives were victims was used to identify many of them.
Assistant Police Chief Tim Smith said: "This has been an incredibly important process and our team has been working hard to provide answers to concerned families who fear their loved one may be among those whose tragic journey has ended behind us.
"Our priority has been to identify the victims, preserve the dignity of the people who died and support the friends and family of the victims.
"It remained of paramount importance for us to ensure that an individual's relatives were informed and had time to absorb this tragic news before we publicly confirmed the identity of their loved one."
