In 1993 young women began disappearing in the Mexican border town of Ciudad Juárez.

Hundreds were reported to have been kidnapped and killed.

Some of the first victims weren’t discovered until nearly 10 years later.

In 2013, Mike Lanchin spoke to Oscar Maynez, a forensic scientist who used to work in the city and to Paula Flores, the mother of one of the murdered girls.
