Mexican authorities found three dead bodies of men they said were members of the group that killed 72 migrants in Tamaulipas last month, La Cronica reported. One of the witnesses, a Honduran migrant who escaped, identified the men. They were found along the side of the road near where the massacre happened after members of the Mexican Navy received an anonymous phone tip. The army killed three other alleged members of the gang that killed the migrants, and another was captured. The Zetas drug trafficking organization are said to be responsible for the massacre. The gang has branched into human trafficking in recent years, which the United Nations estimates is a $7 billion per year business.
