Local police in Mexico involved in 2001 massacre, officials say

MEXICO CITY - Federal prosecutors say that local police in the city of San Fernando in northern Mexico were involved in the 2011 massacres of 193 mainly Central American migrants whose bodies were found in mass graves.

The claim appeared in a memo sent by Mexico's Attorney General's Office to The National Security Archive, a Washington D.C.-based research organization that solicited the information under Mexican transparency laws. It published the memo on its website on Monday and highlighted the similarities in the case to what happened with the 43 teachers college students who disappeared in southern Guerrero state in September.

The students were abducted by local police linked to a drug cartel in Guerrero. In San Fernando, local police worked as lookouts for the Zetas drug cartel, according to the memo.
