TEPOTZOTLAN, Mexico (AP) — Dozens of women and men searched a garbage dump outside Mexico’s capital Friday looking for signs of missing loved ones, working without the protection of authorities as part of a nationwide effort to raise the profile of those who risk their lives to find others.

Under a blazing sun and amid foul odors, they picked through the dump and other sites in the town of Tepotzotlan in Mexico state, which hugs Mexico City on three sides.

Hundreds of collectives across Mexico are participating in search operations this weekend to draw attention to the work they are left to do without official help in a country with nearly 100,000 people registered as missing.

The work is dangerous. The United Nations High Commissioner for Human Rights has documented nine cases since 2019 of women who were slain over their work hunting for missing relatives. Other organizations in Mexico have recorded even more cases.
