The driver of a truck in which 39 people were found dead appeared in a British court via video link on manslaughter and people-trafficking charges on Monday.
The Vietnamese families of suspected victims spoke of their despair.
The discovery of the bodies in a refrigerated truck on an industrial estate east of London has shown a spotlight on the illicit global trade in people which sends the poor of Asia, Africa and the Middle East on perilous journeys to the West.
Driver Maurice Robinson appeared in Chelmsford Magistrates’ Court via video link.
The 25-year-old, wearing a gray sweatshirt, spoke only to confirm his name and address.
Robinson faces 39 counts of manslaughter as well as charges of conspiracy to traffic people, conspiracy to assist unlawful immigration and money laundering, police said.
“This involves a global ring facilitating the movement of a large number of immigrants into the UK,” prosecution lawyer Ogheneruona Iguyovwe told the court.
She said that other suspects were still wanted.
Robinson made no application for bail. He was remanded in custody until November 25, when the case will continue at the Old Bailey, London’s Central Criminal Court, and he will enter a plea.
The driver was arrested shortly after the discovery of the bodies in the early hours of October 23 a few miles from the English port of Purfleet.
The container had travelled from the Belgian port of Zeebrugge.
“The whole nation and indeed the world have been shocked by this tragedy, and the cruelty of the fate that has been suffered by innocent people, who were hoping for a better life in this country,” British Prime Minister, Boris Johnson, wrote in a book of condolences.
He added: “We mourn those who have lost their lives. Our thoughts are with their families far away.”
British police initially said the 39 dead were thought to have been Chinese but it later emerged that many were from Vietnam, where communities have been plunged into despair.
The suspected victims hail from Vietnam’s northern rice-growing areas of Nghe An and Ha Tinh, two of the communist-ruled nation’s poorest provinces.
Some families prayed their loved ones would still be found safe and sound.
“If I could travel back in time, I wouldn’t have let him go this way,” Hoang Thi Ai, mother of Hoang Van Tiep, 18, who is feared among the dead, said.
“I clean his room every day with the hope that he wasn’t in that deadly truck,” she said.
Police have said very few of the victims were carrying official identification and that they hope to identify the dead through fingerprints, dental records and DNA, as well as photographs from friends and relatives.
The Vietnamese government said Britain had sent dossiers regarding four of the people found in the truck, seeking help in identifying them.
About 70 per cent of Vietnamese trafficking cases in Britain between 2009 and 2016 were for labour exploitation, including cannabis production and work in nail salons, the British government said in 2018.
