Death in Haditha

"Salinas then stated that he could see the enemy so Kallop told them to 'take the house,' " according to an NCIS summary of an interview with Kallop. The interview provides the first evidence that an officer ordered the attack.

Richard McNeil, a lawyer who represents Kallop, declined to comment about him or his role, but he warned that "typically in an NCIS investigation, the narratives are always slanted to the interpretation of the government."

Wuterich, Salinas, Tatum and Lance Cpl. Humberto M. Mendoza formed a team to attack the house, launching grenades first and then busting through the door.

"I told them to treat it as a hostile environment," Wuterich told investigators. "I told them to shoot first, ask questions later."

Defense attorneys have argued that the men were following their "rules of engagement" when they shot into the homes, using effective techniques in a difficult environment.

The Marine division's rules-of-engagement card in effect at the time in western Iraq instructed Marines to "ALWAYS minimize collateral damage" and said that targets must be positively identified as threats before a Marine can open fire. It also told Marines that "nothing on this card prevents you from using all force necessary to defend yourself."

After entering the first house through a kitchen, Tatum told investigators, he heard what he believed was an AK-47 rifle being "racked," or readied to fire, around a corner. He and Salinas tossed grenades into the room, according to the documents. Waleed Hasan, 37, was killed. Khamisa Ali, 66, was shot dead in the hallway before four others were killed in a bedroom by grenades and rifle fire.

Nine-year-old Eman Hamed told investigators that a grenade landed near her grandfather's bed and exploded, sending shrapnel through the room. Her mother and 4-year-old brother were killed as she huddled, injured, with another brother, Abid, 6, who survived. "All rooms," Abid told investigators. "They were shooting in all rooms."

Several Marines said they quickly cleared the home by fire, shooting through the dust, debris and darkness to eliminate what they believed was a threat.

From there, Wuterich, Mendoza and Tatum said, they moved to a second house after suspecting that insurgents might have escaped. Mendoza told investigators that the Marines approached the second house the same way they did the first, treating it as hostile, according to his sworn statement. Mendoza said he shot a man, 43-year-old Yunis Rasif, through the house's glass kitchen door.

"I fired because I had been told the house was hostile and I was following my training that all individuals in a hostile house are to be shot," Mendoza told investigators. The Marines then entered the house and tossed grenades before firing into a back bedroom, which they later found was filled with women and children.

"Knowing what I know now, I feel badly about killing Iraqi civilians who may have been innocent, but I stand fast in my decisions that day, as I reacted to the threats that I perceived at the time," Tatum said. "I did not shoot randomly with the intent to harm innocent Iraqi civilians."
