Over a ten year period nearly four hundred women have disappeared in Ciudad Juarez, a city in Mexico near the border with the US. Here there were many factories employing hundreds of women in transit. It become known as the City of the Lost Girls.
Years later bodies have been found but justice for the women's families has been elusive. Amnesty International are calling for a full and prompt investigation and now Channel 4 are making a documentary asking who's responsible.
Rupert Knox of Amnesty and Channel 4 reporter Sandra Jordan join Martha to discuss. Unreported World: The City of Lost Girls is on Channel 4 tonight at 8pm
