Book Launch—City of Omens: A Search for the Missing Women of the Borderlands

What’s Really Behind the Missing Women at Mexico’s Border?


Tijuana is one of the most violent cities in Mexico and the city has become increasingly dangerous for women. University of California, San Diego, epidemiologist Dan Werb calls the phenomenon of dead and missing women at the border a femicide. 

Werb, who has been tracking HIV in Tijuana since 2013, has been on a quest to find what’s driving the city’s rising female homicide rate. His research and conclusions are detailed in his new book, City of Omens: A Search For the Missing Women of the Borderlands.

Despite its reputation as a carnival of vice, Tijuana was, until recently, no more or less violent than neighboring San Diego, its sister city across the border wall. But then something changed. Over the past 10 years, Mexico’s third-largest city became one of the world’s most dangerous. Tijuana’s murder rate skyrocketed and produced a staggering number of female victims. Hundreds of women are now found dead in the city each year, or bound and mutilated along the highway that lines the Baja coast.

When Dan Werb began to study these murders in 2013, rather than viewing them in isolation, he discovered that these murders could only be understood as one symptom among many. Environmental toxins, drug overdoses, HIV transmission: all were killing women at overwhelming rates. As an epidemiologist, trained to track epidemics by mining data, Werb sensed the presence of a deeper contagion targeting Tijuana’s women. 

Werb’s search for the ultimate causes of Tijuana’s femicide casts new light on immigration, human trafficking, addiction, and the true cost of American empire-building.
