EL RINCON DE SAN ILDEFONSO, Querétaro, Mexico — On a Saturday in early May, Maria Eugenia Chavez Segovia phoned her youngest son to tell him she was coming home to Mexico City, and then to the remote village in south Querétaro where she was raised.
Chavez Segovia had spent the previous three months in northern Baja California, hoping to slip across the border undetected to join some of her siblings in the San Joaquin Valley for seasonal agricultural work.
Caught twice trying to cross illegally into the United States and tired of Tijuana, the 41-year-old single mother was ready to give up on going north.
That Monday, her youngest son, José Jael Antonio Chavez, waited for her arrival in Mexico City. But she never came.
