This time, he describes the horror of the past 24 hours from memory - a memory which is certain to haunt him for the rest of his life.
Dhai Adnan Saleh is both extremely lucky and extremely brave.
He is one of very few survivors of a mass killing by police commandos and he has dared to speak publicly about what happened.
He and at least nine other relatives - all Sunni Muslims - were detained earlier this month, apparently because they were suspected of being insurgents following a shoot-out in their area.
"The police started to beat us, tied our hands and blindfolded us," he said.
"We were left from 5.30 that evening inside a kind of container that had no air vents. After one hour, we lost consciousness and some people began to die, the others were dead by one o'clock in the morning."
The other survivors who were in a serious condition were treated at Baghdad's main hospital under heavy guard by police commandos.
The BBC was not allowed to speak to them and was not allowed to enter the morgue where the bodies were kept.
