Chile convicts three agents in 1976 Washington DC car bomb that killed Letelier

Two people killed in the car bombing: Orlando Letelier, a former Chilean minister and ambassador, and Ronni Karpen Moffitt, a 25-year-old American colleague, on September 21, 1976.
Justice took 49 years and 97 days to arrive
Chile's ambassador to Washington reflected on the delayed conviction for the 1976 bombing that killed Ronni Karpen Moffitt.

Fifty years after a car bomb tore through a Washington morning and silenced two lives on Massachusetts Avenue, a Santiago court has at last named the hands behind the act. Three former agents of Pinochet's feared secret police have been sentenced to fifteen years for the murder of Ronni Karpen Moffitt, a 25-year-old American whose case long languished in the shadow of her more prominent colleague, exiled Chilean ambassador Orlando Letelier. The conviction is a reminder that justice, when it finally arrives, arrives not as triumph but as reckoning — proof that the machinery of state terror, however it renames itself, cannot indefinitely outrun accountability.

  • A car bomb on a Washington boulevard in 1976 killed two people in an instant, but it would take nearly five decades before a court held anyone responsible for one of those deaths.
  • Ronni Karpen Moffitt's case was sidelined for years because early investigations centered on the more politically prominent Letelier, leaving her murder effectively unprosecuted until a 2012 appeals ruling forced it open again.
  • The three convicted agents — Pedro Espinoza, José Zara, and Raúl Iturriaga — operated under Dina chief Manuel Contreras, surveilling Letelier, tracking his movements, and planting the device as part of a systematic campaign to eliminate dissidents abroad.
  • Letelier himself had been stripped of his Chilean citizenship just eleven days before the bombing, yet stood before 75,000 people at Madison Square Garden that same night to declare he would die a Chilean — a defiance that made him a marked man.
  • Family members and former diplomats marked the verdict with grief and resolve, with Moffitt's niece calling it a reminder that the pain of the Chilean people 'will not be forgotten,' and Letelier's son urging the United States to pursue its own accountability.
  • Though the bombing once strained US-Chile relations and prompted an arms embargo, Pinochet's junta simply dissolved Dina and relaunched it under a new name — a pattern the conviction now forces back into historical view.

On a September morning in 1976, a car exploded on Massachusetts Avenue in Washington DC, killing Orlando Letelier — a former Chilean minister living in exile — and Ronni Karpen Moffitt, a 25-year-old American colleague. It would take fifty years for a court to answer for Moffitt's death.

Last week, a Santiago court sentenced three former agents of Chile's Dina secret police — Pedro Espinoza, José Zara, and Raúl Iturriaga — to fifteen years in prison. All three had served under the feared intelligence apparatus that General Pinochet used to hunt political enemies beyond Chile's borders. The bombing was deliberate: the agents surveilled Letelier, tracked his movements, and planted the device on orders from Dina chief Manuel Contreras. Eleven days before the explosion, Pinochet had revoked Letelier's citizenship. That same night, Letelier stood before 75,000 people at Madison Square Garden and declared he would die a Chilean. He was forty-four when the bomb killed him.

Moffitt's case had long been eclipsed by Letelier's. High-ranking Chilean officials and American collaborator Michael Townley were convicted in the 1990s in connection with the attack, but because early investigations centered on Letelier, Moffitt's murder stalled. It was not until 2012 that a Santiago appeals court ruled her case must be prosecuted separately.

Those who knew the victims marked the verdict with a mixture of relief and grief. Former Chilean ambassador Juan Gabriel Valdés noted that justice had taken "49 years and 97 days to arrive." Moffitt's niece Rebecca Karpen called the sentences a reminder that the countless lives damaged by the Pinochet regime are still being fought for. Letelier's son urged the United States to pursue its own accountability.

The bombing had once strained US-Chile relations, prompted a congressional investigation, and led to an arms embargo. Pinochet's response was to formally disband Dina — and quietly reconstitute it under a new name within months. The machinery of repression changed its label and carried on. The conviction, arriving half a century later, insists that history has a longer memory than those who tried to bury it.

On a September morning in 1976, a car rounded a bend on Massachusetts Avenue Northwest in Washington DC and exploded. Inside were Orlando Letelier, a former Chilean minister and ambassador to the United States, and Ronni Karpen Moffitt, a 25-year-old American working alongside him. Both were killed instantly. It would take fifty years for a court to hold anyone accountable for Moffitt's death.

Last week, a Santiago court sentenced three former agents of Chile's secret police—Pedro Espinoza, José Zara, and Raúl Iturriaga—to fifteen years in prison for their roles in the bombing. Judge Paola Plaza, who specializes in human rights cases, handed down the convictions. All three men had served in the Dirección Nacional de Inteligencia, or Dina, the feared intelligence apparatus that General Augusto Pinochet used to hunt down his political enemies at home and abroad. Espinoza and Iturriaga were already imprisoned for other atrocities; Zara had been released last August after completing a fifteen-year sentence, only to be arrested again.

The bombing was no random act. According to the court, the agents, operating under the direction of notorious Dina chief Manuel Contreras, had devised a plan to carry out murders on foreign soil. They surveilled Letelier, tracked his movements, and planted the device. Letelier had become a vocal critic of the dictatorship while living in exile in America. He arrived in the United States in January 1975, having spent a year imprisoned in a concentration camp on a frozen Patagonian island before being moved to another on Chile's coast. On September 10, 1976—eleven days before the bombing—Pinochet revoked his citizenship. That same night, Letelier stood before seventy-five thousand people at Madison Square Garden and declared: "I was born a Chilean, I am a Chilean, and I will die a Chilean. They were born traitors, they live as traitors, and they will be known forever as fascist traitors." He was forty-four years old when the bomb killed him.

Moffitt's case had languished in the shadows of Letelier's for decades. High-ranking Chilean military officials were convicted in connection with the bombing during the 1990s, as was Michael Townley, an American collaborator with Dina who confessed in 1978. But because Moffitt was an American and the initial investigations centered on Letelier, her case stalled. It was not until 2012 that a Santiago appeals court ruled that Moffitt's murder must be reopened and prosecuted separately, since the perpetrators were Chilean nationals.

Juan Gabriel Valdés, who served as Chile's ambassador to Washington until March of this year and knew both victims during his own exile in the capital, posted on social media that "justice took 49 years and 97 days to arrive." He remembered Moffitt's cheerful morning greetings at the Institute of Policy Studies where she and Letelier worked together. Rebecca Karpen, Moffitt's niece, said in a statement that the sentences were "not just a victory for our family, but are a reminder that the countless lives ruined by the Pinochet regime are still being fought for, that the pain of the Chilean people will not be forgotten." Juan Pablo Letelier, the former ambassador's son, called on the United States to pursue its own justice against those responsible.

The bombing had reverberated across the Atlantic at the time. The brazen killing of a former ambassador on American soil strained relations between Chile and the United States—relations that had been warm when the US backed Pinochet's 1973 coup with financial support. Congress launched an investigation and imposed an arms embargo on Chile. Pinochet's junta responded by disbanding Dina, though it quietly established a replacement agency, the Central Nacional de Informaciones, within months. The machinery of repression simply changed its name and continued.

I was born a Chilean, I am a Chilean, and I will die a Chilean. They were born traitors, they live as traitors, and they will be known forever as fascist traitors.

These sentences are not just a victory for our family, but are a reminder that the countless lives ruined by the Pinochet regime are still being fought for.

Why did it take fifty years to convict anyone for Moffitt's death when Letelier's killers were prosecuted in the 1990s?

Model

Because she was American and he was Chilean. The initial investigation focused on Letelier as the primary target. Moffitt was treated as collateral damage. It wasn't until 2012 that a court ruled her case had to be reopened and prosecuted separately, since the perpetrators were Chilean nationals and fell under Chilean jurisdiction.

Inventor

So the secret police knew exactly what they were doing when they planted that bomb?

Model

Yes. According to the court ruling, Contreras and his agents planned extrajudicial murders on foreign soil. They surveilled Letelier, tracked his schedule, and executed the operation deliberately. This wasn't a mistake or an accident.

Inventor

What was Letelier doing that made him such a target?

Model

He was a prominent voice against the dictatorship while living in exile in Washington. He'd been imprisoned in concentration camps, stripped of his citizenship, and then he went to Madison Square Garden and told seventy-five thousand people that Pinochet and his junta were fascist traitors. Eleven days later, he was dead.

Inventor

And Moffitt—was she involved in politics, or was she simply in the wrong place?

Model

She was working with Letelier at the Institute of Policy Studies. She was twenty-five years old. The court convicted the agents for her murder specifically, not as a secondary victim. She was targeted because she was with him.

Inventor

What does this conviction mean now, fifty years later?

Model

It means the Chilean state has finally acknowledged what happened and held people accountable. But it also means the machinery that did this—Dina—was never truly dismantled. It was renamed and continued operating. Justice arrived, but only after decades of silence.
