A shadow hangs over El Rosario where each year millions of monarch butterflies alight on the reserve's fir trees. Two local protectors of Mexico's monarch preserve have been killed, and so far, no one can say what happened to them.
The increasing number of fatal acts of police are among the emerging concerns addressed by the Pastoral of Favelas, an archdiocesan commission created 42 years ago to respond to the needs of Rio’s slum dwellers.
Mr. LeBarón, the family's spokesperson, said he hopes he can channel the grief and anger over the killings into a broad social movement. “We want to unite the whole country. We want a social movement, not a political one,” he said.
