LONDON — All 39 people who were discovered dead in a refrigerated trailer in southeast England last month have been identified, the police said on Thursday.

The authorities did not reveal the names of the eight women and 31 men whose bodies were found in a trailer in an industrial park in Grays, Essex, on Oct. 23. But the families of the victims were notified, according to a statement from the Essex Police.

The police confirmed that all the victims — who were believed to have been transported to England through a global human-trafficking network — were from Vietnam.
