She stood still for more than an hour. Her torturers refused to let her go to the bathroom. When she urinated on the floor, they taunted her.
"They would say to me, 'You Communists have no mothers. You have no morals. You have no country.'"
Caballero spent hours interrogating Murillo in the clandestine jail -- asking about everything from leftist guerrilla activities in Central America to whether she had a boyfriend.
In interviews in Toronto, where Caballero has lived with his wife and children since he fled Honduras in 1986, he recalled how Murillo was brutalized. When she arrived, he said, her body was shrunken from weeks without food. He confirmed that she and Flores were shocked with electricity.
"They attached cables with clips to their genitals, on their sides and on their backs," he said.
Caballero says he never raised a hand against Murillo, but only questioned her.
Murillo, arching her thin eyebrows, says she remembers Caballero as a torturer.
"I remember perfectly well what he did to me," she said, although she refused to describe precisely what it was. "His story that there were some who tortured and others who just interrogated was a lie. Everyone in the jail tortured."
After several weeks at INDUMIL, Murillo says, she heard Caballero ask: "Is she still alive? Why haven't they killed her?"
'Mr. Mike' visits
ABOUT TWO MONTHS into her captivity, an American who seemed to be a regular visitor to the area came to her cell, Murillo says. Whenever he came, she would hear her captors shouting, "Here comes Mr. Mike."
"It was like an uncle coming to visit," she recalled. "I could tell he did not live there, but he was always welcome."
On this occasion, Murillo says, the Hondurans dressed her in a rough cotton shirt and pants, and secured her blindfold.
After being blindfolded for so long, Murillo says, her other senses had become more acute. She heard the footsteps of three or four people enter her cell. Then she heard the sounds of a pencil scribbling on a pad and the passing of the pad from one person to another.
One of her interrogators began to speak. It sounded as if he were reading, Murillo recalls. And although he spoke in Spanish, with a Honduran accent, his questions were not grammatical.
Murillo remembers thinking: "These are not the questions of Battalion 316. They are the questions of Mr. Mike."
He was writing them and passing them to the Honduran interrogator, instead of speaking himself, she believes. And unlike the usual interrogations, there was no torture.
The man she believed to be an American remained silent through the 10-minute interrogation.
