MEXICO CITY (Reuters) - Flora Marcelo wrote her appeal on a white wall outside the U.N. human rights office in Mexico City, using a finger dipped in her own blood: "Justice for the disappeared."
At least five women joined Monday's protest, some drawing their blood with the help of a catheter, to bring attention to the plight of children and other relatives who have gone missing or been killed amid the violence of Mexico's long drug war.
Marcelo, 36, has spent weeks camped outside government offices along with dozens of other women in a bid to highlight their cases. This protest was a "desperate" measure, she said.
"They don't listen to us, and I want justice for my daughter," Marcelo said as blood flowed from her arm through a slender plastic tube.
Mexico has registered nearly 80,000 missing people, most of them victims of gang-related violence since the start of a "war on drugs" in 2006. Officials say around half of those could be unidentified bodies in morgues that are under-funded and ill-equipped to deal with the avalanche of homicides.
Despite a new legal framework and the establishment of a national search commission, the number of missing keeps rising. Support groups of family members, mostly mothers, have formed to search in clandestine graves scattered across the country.
Marcelo's 13-year-old disappeared in October from their home in Guerrero, one of Mexico's most violent states. Several days later, her body was found, dismembered. Marcelo discerned it was her daughter from the clothes discovered nearby.
Montserrat Ramirez, also from Guerrero, said her husband disappeared in April.
