Brother of a Vietnamese woman tells the BBC he fears she is among the Essex lorry dead. Pham Tra My, 26, has not been heard from since she sent urgent messages home saying she could not breathe. Last know location was Belgium after a failed attempt to cross to the UK. 
Ms Pham's brother asked the BBC to provide information to Essex Police in the hope that it will assist in identifying her.
Ms Pham's family say £30k was paid to people smugglers and she had made one failed attempt to enter the UK. They were aware she was making another attempted crossing - and her last messages came at 10.30pm on Tuesday night - 2 hours before the trailer reached the UK.
We don't know if Ms Pham is among the victims. This has not been confirmed by the police. But the messages she sent to her family, hours before the dead were found, are in the next tweet. Please be warned that they are upsetting.
"I am really, really sorry, Mum and Dad, my trip to a foreign land has failed," Ms Pham wrote. "I am dying, I can't breathe. I love you very much Mum and Dad. I am sorry, Mother."
Ms Pham’s brother told the BBC that her journey to the UK had begun on 3 October. She had instructed the family not to contact her because “the organisers” did not allow her to receive calls.
“She flew to China and stayed there for a couple days, then left for France. She called us when she reached each destination," Mr Pham told the BBC. "The first attempt she made to cross the border to the UK was 19 October, but she got caught. and turned back."
At time of writing, the BBC has been provided information on THREE Vietnamese nationals whose families believe they were in the trailer based on their movements, messages and loss of contact since Tuesday/Wednesday.
Update: Now at least six. Clarification on the payments. Families pay a deposit to smugglers to get their relative on the move. Some of the families the BBC is in contact with have received that money back since the deaths were discovered.
