On December 13, 1973, the following individuals were detained at the Los Capuchinos Church in Santiago:

Bautista VAN SCHOWEN VASEY, 30 years old, married, surgeon, member of the Political Commission of the Revolutionary Left Movement (MIR).

Patricio MUNITA CASTILLO, 22 years old, law student. The aforementioned individuals, in addition to a priest from the Los Capuchinos Church and another person whose identity remains unknown, were detained in the afternoon of December 13, 1973, from inside the aforementioned church by a contingent of carabineros officers and plainclothes personnel, in the presence of witnesses.

According to eyewitness accounts of the arrest, the detainees did not resist and were forced by their captors into a Carabineros bus, in which they were transported to an unknown location. The priest was released after eight days of detention.

Van Schowen, Munita, and the third person whose identity is unknown had arrived at the aforementioned church at the beginning of December, where they were temporarily staying.

Bautista Van Schowen was a well-known leader of the Revolutionary Left Movement (MIR), who had been publicly sought since September 11 of that year to present himself before military authorities. The press at the time reported that the Military Junta offered a reward of Eº 500,000 to the person "who provided information allowing for the location and arrest by public force" of some of the individuals mentioned on a list, which included the victim.

Furthermore, the newspaper "El Mercurio" of Santiago reported in its August 21, 1974 edition that "...due to serious crimes, which are sufficiently established in the proceedings being followed against Bautista Van Schowen Vasey in the First Military Prosecutor's Office of Santiago, this extremist element was arrested on December 13, 1973, shortly after the Military Pronouncement of September 11 last.

Currently... he is being held in a prison facility in the country."

Similar information was provided that same month by the Ministry of the Interior during the judicial investigation into his disappearance, stating that "Bautista Van Schowen is at the disposal of the First Military Prosecutor's Office of Santiago." The Ministry retracted this the following month, noting that "an involuntary factual error was made, since the person who was actually arrested in the Santiago Public Jail... was Roberto Fernando Van Schowen Vasey, and not his brother Bautista."

Finally, in February 1978, in response to a request from the Inter-American Commission on Human Rights of the Organization of American States (OAS), the Military Junta replied that Van Schowen "...traveled to Cuba on February 2, 1973, with Chilean passport No. 2743, and there is no record of him having re-entered national territory."

In other reports to the Courts of Justice, the authorities of the time denied that Bautista Van Schowen had been detained or that he was at the disposal of any court.

However, this Commission cannot accept the official version that the victim left the country in February 1973 without re-entering, or that he was not detained, given that after the indicated date he was one of the most wanted political leaders, with the Military Junta having offered a monetary reward for his capture.

Furthermore, there are eyewitnesses to his arrest by police officers in December 1973, in addition to the confusing official and journalistic versions regarding his legal status.

Regarding Patricio Munita, his lifeless body was found on Américo Vespucio at the 3,600 block on December 14, and was subsequently buried in section 29 of the General Cemetery by order of military personnel who were present at the cemetery, as established by eyewitnesses to the event. Two months later, his family succeeded in exhuming his body and identifying it.

Regarding the third person detained alongside Van Schowen and Munita, it has not been possible to date to establish his identity or his fate.

In accordance with all the aforementioned evidence, this Commission has reached the conviction that in the case of Patricio Munita, an execution was committed outside of all legality by State agents, and in the case of Bautista Van Schowen, it is a case of forced disappearance committed by the same agents, considering both as victims of grave human rights violations.
