Chilean mail bombs case
2001 terrorist attack in Chile
The Chilean mail bombs case was a terrorist attack which occurred on 27 September 2001 at the United States Embassy in Chile, perpetrated by Humberto López Candia, an informant for the Public Security Coordinating Council (CCSP). better known by the informal name from "La Oficina", and by Lenin Guardia Basso, a Chilean sociologist and intelligence analyst, known for having contributed to the dismantling of crime and drug trafficking during the transition to democracy in Chile.
Events
On September 27, 2001, a letter bomb arrived at the United States embassy in Santiago de Chile. It consisted of an electric detonator, ammonium nitrate, trinitrotoluene, a clothespin, an AA battery, and wires. The bomb was successfully destroyed in a controlled demolition. On the same day, another letter-bomb, this one consisting of a solid substance with a high content of nitrates, as well as an A battery and two electrical cables, arrived at the office of lawyer Luis Hermosilla.
The following day, Lenin Guardia called the La Moneda Palace and provided information on the case to Guillermo Miranda, chief of staff of the Ministry of the Interior. In parallel, Humberto López (former member of the MIR and former informant for La Oficina) called Radio Bío-Bío to report what had happened. Guardia also contacted Nelson Mery Figueroa, Chilean detective and then-director of the Investigations Police of Chile, to whom he pointed out that the letter-bombs corresponded to propaganda actions by the supposedly regrouped Manuel Rodríguez Patriotic Front (in Spanish, Frente Patriótico Manuel Rodríguez, FPMR). Guardia then sold Mery a list with the names of public figures against whom the FPMR would allegedly attack: among them were the director of the DISPI, Gustavo Villalobos; lawyer Isidro Solís; Cardinal Francisco Javier Errázuriz; various army officers; and Mary himself.

Why this record matters
The subject matters to the general reference register because the source frames it as 2001 terrorist attack in Chile. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q18223446. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2001.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
