In the civil aspect, the visiting judge granted the filed claim and ordered the state to pay a total compensation of $2,780,000,000 (two billion seven hundred eighty million pesos) for moral damages to the victims' families.

The extraordinary visiting judge for human rights violation cases within the jurisdictions of the Courts of Appeals of Temuco, Valdivia, Puerto Montt, and Coyhaique, Álvaro Mesa Latorre, issued sentence number 78 on the matter, sentencing 23 retired military personnel and Army collaborators for their responsibility in the qualified homicides and illegal coercion of Florentino Alberto Molina Ruiz, Juan Antonio Chávez Rivas, Víctor Hugo Valenzuela Velásquez, Juan Carlos Ruiz Mancilla, Amador Francisco Montero Mosquera, Pedro Juan Mardones Jofré, and Carlos Aillañir Huenchual, perpetrated in the commune of Temuco in November 1973.

Finally, José Raúl Inzunza Reyes was sentenced to 427 days in prison as the perpetrator of 7 crimes of illegal coercion.

In the sentence, Judge Mesa Latorre established the following facts:

A.- That, immediately following the military coup of September 11, 1973, the armed forces and security forces took control of the city of Temuco, with Colonel Hernán Jerónimo Ramírez Ramírez, Commander of the "La Concepción" Regiment of Lautaro (deceased, as recorded on page 6,060 of volume XVII), establishing himself as Intendant; and Colonel Pablo Iturriaga Marchesse (deceased, as recorded on page 1,298, volume IV), Commander of the No. 8 "Tucapel" Infantry Regiment of this city, as Governor of Temuco, who also remained as Chief of the Temuco Garrison.

B.- That on the same day, September 11, 1973, Temuco lawyer Oscar Alfonso Ernesto Podlech Michaud, who was also a Reserve Lieutenant in the Chilean Army, was called to collaborate with the new regime to support the work of the Military Prosecutor's Office operating within the unit, which was in charge of the Second Commander, Major Luis Jofré Soto (deceased, as recorded on page 1,295, volume IV).

This officer, however, had to assume greater duties as Second Commander of the Tucapel regiment shortly thereafter. From that day forward, civilians began arriving at the regiment after being summoned to appear before the Military Prosecutor's Office via communiqués published in the written press and on the radio, or having been brought in as detainees from different parts of the region by police and military patrols.

Given the high number of detainees and people called to testify, the Military Prosecutor's Office was reinforced to carry out its work with Judiciary officials requested from the Temuco Court of Appeals by the aforementioned lawyer Podlech Michaud, who, acting as Ad-Hoc Prosecutor, made a presentation to the Plenary of the Appellate Court (Minutes from page 3010 to 3011, volume IX), after which some clerks from different courts and a Court Rapporteur were assigned on service commission.

Due to a lack of knowledge in criminal procedural matters, added to his weak character and his work as Second Commander of the regiment, Major Luis Jofré Soto began delegating functions as Military Prosecutor to the lawyer Oscar Alfonso Ernesto Podlech Michaud, advisor to the Prosecutor's Office, who began to hold the position of de facto Prosecutor, to the point that he conducted jail visits and that lawyers, family members, and even ecclesiastical dignitaries consulted him regarding the fate of the detainees.

However, Major Jofré Soto continued to sign administrative documents most of the time and participated in some interrogations of detainees.

C.- That the people called to appear before the Military Prosecutor's Office and those brought in as detainees were kept in facilities located next to the guardhouse and in the large gymnasium. Once interrogated by personnel from the Military Prosecutor's Office, by detectives Aquiles Alfonso Poblete Müller (deceased, as recorded on page 3,800, volume XI), Daniel San Juan Clavería, and Hernán Raúl Quiroz Barra of the Investigative Police attached to the regiment, or by the officers themselves who participated in these activities—among whom were Jaime Guillermo García Covarrubias, Raimundo Ignacio García Covarrubias, Pablo Domingo Gran López, Mario Hernán Arias Díaz (deceased, as recorded on page 7,531, volume XXI), Carlos Eduardo Oviedo Arriagada, Norberto Francisco Uribe Moroni, Pedro Guillermo Manuel Tichahuer Salcedo, Romilio Osvaldo Lavín Muñoz, and non-commissioned officers, among whom were Juan Bautista Labraña Luvecce, Orlando Moreno Vásquez, and Raúl Binaldo Schonherr Frías—some were released, others were sent to their homes under house arrest, and others were taken to the public jail where they remained while their procedural situation was resolved.

D.- That also by September 1973, in the No. 8 "Tucapel" Infantry Regiment of Temuco, there existed the Second Section of Information and Intelligence, which was in charge of Captain Nelson Manuel Uldaricio Ubilla Toledo (deceased, as recorded on page 1,296, volume IV), under whose authority some non-commissioned officers of that institution also performed duties, including Juan Bautista Labraña Luvecce, Orlando Moreno Vásquez, and Raúl Binaldo Schonherr Frías.

This work was reinforced after September 11, 1973, with the addition of Investigative Police officials Aquiles Alfonso Poblete Müller (deceased, as recorded on page 3,800, volume XI), Daniel San Juan Clavería, and Hernán Raúl Quiroz Barra, mentioned above, and Carabineros, including Omar Burgos Dejean, who provided political information to the aforementioned officer regarding all those persons subject to an investigation by the Military Prosecutor's Office.

Likewise, some officers, including Manuel Abraham Vásquez Chahuán, as well as enlisted men and conscripts of the regiment, joined the intelligence tasks. As the days passed, the Military Prosecutor's Office and the Second Intelligence Section began to work together to interrogate the detainees, as in this case, who remained incarcerated in the jail or in some facility of the Tucapel regiment.

To coordinate this work, two locations were set up in the military unit, one located between the Headquarters Company and the Mortar Company, and another in an old, disused gymnasium located next to the conscript soldiers' "mess hall." In this way, the detainees were taken to and from the jail to the regiment by military personnel of the Second Section, being interrogated at the Military Prosecutor's Office and physically coerced in one of the aforementioned facilities to "soften them up" before or after these interrogations, as in this case.

In both interrogation and torture rooms, there were implements to tie up the detainees and apply electricity to different parts of their bodies, in addition to applying other types of torture such as kicks and punches, as in this case.

Participating in this task were conscript soldiers, including Manuel Rafael Campos Ceballos, Juan Carlos Concha Belmar, Sergio Orlando Vallejos Garcés, Gabriel Alfonso Dittus Marín, Héctor Mauricio Villablanca Huenulao, Juan Humberto Carrillo Rebolledo, Libardo Schwartenski Rubio, and José Raúl Inzunza Reyes, and a Carabinero, Omar Burgos Dejean, who collaborated with Captain Nelson Ubilla Toledo and the Investigative Police detectives who were there, Aquiles Alfonso Poblete Müller (deceased, as recorded on page 3,800, volume XI), Daniel San Juan Clavería, and Hernán Raúl Quiroz Barra.

Most of the officers of the "Tucapel" regiment and some non-commissioned soldiers from the Headquarters and Services Companies, including José Raúl Inzunza Reyes, from the Mortars, Hunters, and Second Section, also participated in the interrogation and/or torture sessions of detainees in those places, all of whom entered these facilities at different times.

E.- That within the aforementioned military unit, a special group called "Patrulla Brava" (Brave Patrol) or "Patrulla Chacal" (Jackal Patrol) was formed, composed of non-commissioned soldiers and conscripts of the 2nd Hunters Company, including Manuel Rafael Campos Ceballos, Juan Carlos Concha Belmar, Sergio Orlando Vallejos Garcés, Gabriel Alfonso Dittus Marín, Héctor Mauricio Villablanca Huenulao, Juan Humberto Carrillo Rebolledo, and Libardo Schwartenski Rubio, under the orders of Second Lieutenant Manuel Espinoza Ponce (deceased, as recorded on page 1,299, volume IV), who in turn received orders from Lieutenant Manuel Abraham Vásquez Chahuán, who was in command of the Company. This group was in charge, among other functions, of guarding the detainees who were kept in the facilities of the "Tucapel" regiment of Temuco.

F.- That during the days following September 11, 1973, a significant number of people were killed or disappeared in the IX region, with several of these deaths being explained by regional military authorities through the publication of communiqués issued either from the Intendancy or the Temuco Military Garrison.

The communiqué that explained the events subject to this investigation, in light of the evidence gathered in this process, provides an implausible version of how the events of the night of November 10, 1973, unfolded, taking into consideration the statement by Manuel Ángel Fernández Carranza (page 222), who, after the events of November 10, 1973, and upon returning from a mission he was entrusted with toward the Pucón sector in search of guerrillas, was summoned by the then-commander of the No. 8 Tucapel Regiment of Temuco, Pablo Iturriaga Marchesse (deceased, as recorded on page 1,298, volume IV), to inform him that the assault on the ammunition dump had not been such, but rather an execution carried out at the shooting range, information he gave him personally so that he would not hear it through rumors.

G.- That Florentino Alberto Molina Ruiz, member of the Central Committee and Regional Secretary of the Communist Party, was detained and taken from his home on Monday, November 5, 1973, by two Carabineros members of the Civil Commission, who transported him in a red pickup truck to the Second Police Station of Temuco, where he spent the night in a cell.

At dawn the following day, he was transferred to the "Tucapel" Regiment of Temuco by order of the Temuco Military Prosecutor's Office, remaining incarcerated there until the night of November 10, 1973.

During that period, his wife went daily to drop off clothes and food, which were channeled through the guards at the entrance of the military compound. In turn, Molina Ruiz would send her his used clothes as a sign that he was still being held there.

Molina Ruiz, who was missing an arm due to a work accident, was seen as a detainee inside the aforementioned military compound by Hermán Carrasco Paúl, who was also in the same condition, and who stated that both were victims of illegal coercion. He was also recognized due to his disability by some conscripts who guarded them.

H.- That Juan Antonio Chávez Rivas, a student at the State Technical University, Regional Secretary, and member of the Central Committee of the Communist Youth, was detained on November 6, 1973, by two Carabineros members of the Civil Commission, who transported him in a red pickup truck to the Second Police Station of Temuco, where he spent the night.

The following day, he was transferred to the "Tucapel" Regiment of Temuco. Relatives of the detainee approached the military unit to ask about him, where they were told he was not there, despite the fact that he was seen in the courtyard of the military compound, heavily guarded and in very poor physical condition.

I.- That Víctor Hugo Valenzuela Velásquez, a public employee and propaganda secretary of the Communist Youth of Cautín, was detained on November 7, 1973, around 10:00 a.m., at the Real Estate Registrar of Temuco, where he worked.

The arresting personnel, who were dressed in civilian clothes, belonged to the Army Intelligence Service, one of them being a Sergeant of the "Tucapel" Regiment of Temuco. Relatives of the detainee went to the "Tucapel" Regiment, where they confirmed the detention and, for three days, delivered clothes and blankets for him at the guardhouse.

J.- That Juan Carlos Ruiz Mancilla, a Civil Construction student at the State Technical University and member of the Communist Youth, traveled to the city of Punta Arenas, where his parents lived, after September 11, 1973. He was detained there on November 7 of that same year and transported by plane to Temuco, where he was taken to the "Tucapel" Regiment.

K.- That Amador Francisco Montero Mosquera, an Electrical Engineering student at the State Technical University and member of the Communist Youth, was detained at his home on November 7, 1973, by personnel from the Carabineros Civil Commission and transferred to the Tucapel Regiment of Temuco. Relatives went to that place to find out about his situation and to deliver food and clothes.

L.- That Pedro Juan Mardones Jofré, a student at the State Technical University, was detained at his home and transferred to the Tucapel Regiment of Temuco. The conscript soldier of the 2nd Section of the 2nd Hunters Company, Luis Humberto Llamunao Huaiquinao (pages 1234 to 1235 and 1323 to 1324), stated that it was his duty to bring water to Mardones Jofré, who was being held in a storage room located inside a mechanical workshop.

At that moment, he noticed that the detainee had a very badly wounded hand, making it impossible for him to hold the glass offered to him.

M.- That Carlos Aillañir Huenchual, a farmer and supporter of the Unidad Popular government, was detained on November 6, 1973, by a military patrol moving in an institutional 3/4-ton truck. The detention took place in the rural sector of Pelales, in the town of Quepe, where the house of a brother of the detainee was located.

The soldier in charge of the patrol indicated that the detainee was going to be taken to the Tucapel regiment of Temuco.

N.- That at the end of the day on November 10, 1973, while the aforementioned detainees were being held in the "small" gymnasium of the Tucapel regiment of Temuco, guarded by conscript soldiers of the 2nd Hunters Company belonging to the "Jackal Patrol," Lieutenant Manuel Abraham Vásquez Chahuán, Commander of the aforementioned company, and Second Lieutenant Espinoza (deceased, as recorded on page 1,299, volume IV) appeared, accompanied by other military personnel from the regiment.

In addition, an institutional truck parked at the site, backing up in front of the entrance to the facility where the victims were being held. Said vehicle, due to its characteristics, was recognized as the one usually used to transport meat and bread, and on some occasions, to transport conscripts for guard duty relief.

Immediately thereafter, Lieutenant Manuel Abraham Vásquez Chahuán instructed the subordinate personnel to have the detainees board the truck along with them. The truck with the detainees, plus the officers and their companions, then left the scene.

Regarding this same truck, the following day its cleaning was ordered, among others, to conscript soldier Héctor Florentino Navarrete Leiva, who pointed out that it was full of human flesh and brain matter (page 2150).

Ñ.- That minutes later, sentries at the guard post located at the entrance to the military compound known as "Isla Cautín" saw a caravan of institutional vehicles enter the site, composed of at least one Toyota jeep and the truck indicated in the previous paragraph.

O.- That in the final hours of November 10, 1973, the previously identified detainees were taken from the Tucapel regiment of Temuco, loaded into the aforementioned military vehicle, and transported to the shooting range sector of the "Isla Cautín" military compound by the officers and their companions.

In that place, the victims were tied to stakes that had been arranged there in a row. A short time later, the group of military personnel present in that sector was joined by Captain Rodolfo Vargas Campos (deceased, as recorded on page 1,297, volume IV), Sergeant Hernán Rodrigo Santiesteban Domínguez (deceased, as recorded on page 4,953, volume XV), Sergeant Anacleto Aguirre Rivera (deceased, as recorded on page 10,240, volume XXIX), all from the 1st Hunters Company, plus Sergeant José Gajardo Gajardo (deceased, as recorded on page 4,954, volume XV) from the 2nd Hunters Company.

Also part of this entourage was Second Sergeant of the First Hunters Company, Arnoldo Aedo Matus.

P.- That once the patrol commanded by Captain Vargas arrived at the site, he ordered its members to position themselves behind the detainees who were tied to the stakes, with the exception of Second Sergeant Arnoldo Aedo Matus of the 1st Hunters Company, whom he told to move to another, distant location and proceed to fire shots toward the trees located in a specific sector of Isla Cautín.

This Sergeant Aedo Matus was able to observe that the commander of the regiment, Colonel Pablo Iturriaga Marchesse (deceased, as recorded on page 1,298, volume IV), was present at the site, accompanied by an officer of medium-tall stature, and that two civilians were also witnessing the maneuvers in the same sector, recognizing one of them as the legal advisor to the Temuco Military Prosecutor's Office, Oscar Alfonso Ernesto Podlech Michaud.

Q.- That subsequently, the detainees in those conditions were executed at the site one by one and finished off with bursts of gunfire, after which their bodies were sent to the morgue of the Temuco regional hospital where the required autopsies were performed, determining the causes of their deaths as follows: Molina Ruiz, cranial-encephalic explosion, multiple blunt force gunshot wounds; Chávez Rivas, cranial-encephalic explosion, multiple blunt force wounds from firearms; Valenzuela Velásquez, cranial-encephalic attrition, multiple blunt force wounds from firearms; Ruiz Mancilla, shock from comminuted fracture of the pelvis and right femur, multiple gunshot wounds; Montero Mosquera, cranial-encephalic attrition, multiple blunt force wounds from firearms; Mardones Jofré, cranial-encephalic attrition, multiple blunt force wounds from firearms; Aillañir Huenchual, primary shock, multiple blunt force transfixing gunshot wounds to the thorax-abdomen and limbs. Finally, a military communiqué was drafted to be published in the press the following day, reporting an attempted assault on the Isla Cautín ammunition dump by a group of extremists.

R.- That the day after these events occurred, the news appeared in the local written press stating that an assault had occurred on the Isla Cautín ammunition dump of the Tucapel Regiment, in which an undetermined number of extremists had participated, news that was ratified by Colonel Pablo Iturriaga Marchesse (deceased, as recorded on page 1,298, volume IV), which must be contrasted with the statement by Manuel Fernández Carranza, who, after the events of November 10, 1973, and upon returning from a mission he was entrusted with toward the Pucón sector in search of guerrillas, was summoned by the then-commander of the No. 8 Tucapel Regiment of Temuco, Pablo Iturriaga Marchesse (deceased, as recorded on page 1,298, volume IV), to inform him that the assault on the ammunition dump had not been such, but rather an execution carried out at the shooting range, information he gave him personally so that he would not hear it through rumors. During the following days, details continued to appear in the press regarding how these events had occurred and the manner in which military personnel had repelled said attack and subsequently gone out in search of the supposed extremists who were not killed in the confrontation and who managed to flee the scene.

In the civil aspect, the visiting judge granted the filed claim and ordered the state to pay a total compensation of $2,780,000,000 (two billion seven hundred eighty million pesos) for moral damages to the victims' families.
