Scope: this file documents the custodial attack and the legal response. It does not treat allegations against Viviana before trial as convictions, or Bolaños’s competing accounts as proof that he acted under orders.
Detention without a completed trial
Authorities arrested Viviana Gallardo on 12 June 1981 with other alleged members of a small political group known as “La Familia.” The arrests followed a violent police operation in which officers and a taxi driver died. Officials accused the group of armed activity, but Viviana had not been tried or convicted when she was placed in the First Guardia Civil Station in San José.
Her legal status is essential: the state had custody and a duty to protect her. Whatever accusations were pending, punishment could only follow an independent criminal process. The attack inside the cell bypassed that process entirely.
The attack inside the cell
On 1 July 1981, Civil Guard corporal José Manuel Bolaños Quesada entered the station although he was not assigned to guard the three detainees. He reached the cell door and fired through its opening. Viviana was killed. Alejandra Bonilla Leiva and Magaly Salazar Nasser were wounded; contemporary records note that one of the survivors was pregnant.
The attack was not a disputed outside encounter or a death with an unknown assailant. The shooter was identified, prosecuted and convicted. The unresolved element is the reason he acted and whether his conduct was encouraged by anyone else.
The conviction and sentence
Costa Rican courts convicted Bolaños of qualified homicide for killing Viviana, aggravated injury for wounding Alejandra and simple injury for wounding Magaly. Accounts of the sentencing history report an original 24-year term that was reduced to eighteen years. In submissions to the Inter-American Commission in 1982, the government documented the eighteen-year prison sentence.
Bolaños did not serve the full nominal term in closed custody. He received conditional release on 30 September 1987. That release has drawn lasting public scrutiny, but it did not erase the conviction.
An unprecedented international procedure
Five days after the killing, Costa Rica announced that it would bring the case before the Inter-American Court of Human Rights. The state formally asked the Court to determine whether its own authorities had violated rights protected by the American Convention.
In November 1981, the Court declined the direct application because the required procedure before the Inter-American Commission had not been completed. It sent the matter to the Commission. In Resolution 13/83, the Commission examined the domestic record, including the homicide and injury judgments, concluded that Costa Rica had prosecuted and punished the identified perpetrator, declared the petition inadmissible and archived it.
The international disposition did not decide who, if anyone, might have influenced Bolaños. It assessed the state’s judicial response to the identified attack and the procedural route by which the matter reached the regional system.
Changing explanations, no second conviction
Bolaños initially described the killing as revenge. He later claimed that senior figures had ordered it. Historians and journalists have examined those versions, and the contradictions continue to fuel public suspicion. Yet suspicion is not a judicial finding: no other person was convicted of ordering or organizing the cell attack.
Because Bolaños died in 2014 without a judicially tested account resolving those contradictions, the motive remains open. The defensible classification is therefore solved as to the convicted gunman, unresolved as to motive and possible instigation.

What remains unanswered
- Why did Bolaños target the three women that morning?
- Why did his explanations change from personal revenge to a claimed order from above?
- Did any other official facilitate access to the cell, and if so, with what knowledge?
- What institutional reasoning supported conditional release after roughly six years?
Editorial boundaries
- Viviana is not described as guilty of the accusations she had not yet faced at trial.
- Bolaños’s conviction is a fact; his assertions about higher-level orders are allegations that no later conviction confirmed.
- The injuries to Alejandra and Magaly are part of the adjudicated attack and are not omitted.
- Graphic details are excluded where they do not help explain the investigation or judgment.
