"He mumbled something but it was indistinguishable and it was very short."

The "he" was al-Zarqawi, still alive after the bombing:

[A military spokesman] said that when the terrorist "attempted to sort of turn away off the stretcher, everybody resecured him back onto the stretcher. ... He died almost immediately thereafter from the wounds he'd received from this airstrike."

"We did in fact see him alive," Caldwell said. "There was some sort of movement he had on the stretcher and he did die a short time later. There was confirmation from the Iraqi police that he was found alive."

In case you were hoping he suffered, you got your wish.
