Her captors agreed to untie her hands while she slept. They told her they had made anonymous calls to her parents to tell them she was alive. Finally, she says, they promised that when the time came, they would make her death quick.
"I told them, 'When you shoot me, shoot me good so that I die quick,'" Murillo recalled.
"I thought they were going to kill us," she said. "I began to cry."
But Murillo and Flores were not executed. They rode south for 2 1/2 hours to another clandestine jail near a military complex known as INDUMIL, an acronym for Industrias Militares.
Situated among the low hills south of Tegucigalpa, the jail at INDUMIL was a flat, circular building used as a training center for an artillery battalion.
Murillo heard the booms of large guns.
Her captors pushed her into what she took to be a photo lab because of the odor, then cleared the room, saying they didn't want her to commit suicide by drinking chemicals.
Flores was taken away, Murillo says. She did not see him for the remainder of her captivity.
A radio blared all day, but the music couldn't mute the screams of prisoners. Murillo says she particularly remembers the cries of a woman being tortured in the next cell.
"I heard one of the men say he was going to stick a rod inside the woman," Murillo said. "The woman screamed, 'No, no!' And then she just screamed.
"Sometimes it felt as if they were torturing other people to torture me."
Murillo said the torture at INDUMIL "was much more sophisticated."
"They tortured my mind and my body."
Again she was stripped and not allowed to sleep. Her captors came into her cell every 10 minutes to pour water over her head and shoulders.
"It was only this much water," she said, picking up her coffee cup. "But it had ice in it. It was so cold."
Once, her tormentors brought a German shepherd named Mauser into her cell.
She was blindfolded, she recalls, but she could tell that the dog was huge when her captors forced her to touch his broad head.
"He growled all the time and barked," Murillo said. "I thought they were going to let him attack me."
Murillo was told to stand straight and still; if she moved, Mauser would attack, her captors warned. Murillo says she felt Mauser brush her legs as he circled.
