Knowing she was probably close to death the young woman managed to summon the strength to type out a last, desperate text to her family back home in one of Vietnam’s poorest provinces.

Pham Thi Tra My’s family in rural Ha Tinh, on Vietnam’s north east coast, had scraped together £30,000 for her to flee to a better life abroad and she must have felt she owed them an explanation and even an apology.

Within the pitch black confines of the refrigerator unit which was soon to be her grave, and that of 38 fellow migrants, the 26-year-old wrote to her mother what would in effect be her last will and testament.

"I'm sorry Mom. My path abroad hasn't succeed,” she wrote. “Mom, I love you so much! I'm dying bcoz I can't breath...I'm from Nghen, Can Loc, Ha Tinh, Vietnam... I am sorry, Mom".

Poignantly Ms Pham ensured that she made it known in that message where she was originally from.

This is understood to be a common technique used by migrants to ensure the authorities know where to repatriate their bodies, in case they die during what is all too often a perilous journey.
