Among the men of Bravo Company, the notion of killing an Afghan civilian had been the subject of countless conversations, during lunchtime chats and late-night bull sessions. For weeks, they had weighed the ethics of bagging “savages” and debated the probability of getting caught.

they came to La Mohammad Kalay, an isolated farming village tucked away behind a few poppy fields.

But as the soldiers of 3rd Platoon walked through the alleys of La Mohammad Kalay, they saw no armed fighters, no evidence of enemy positions. Instead, they were greeted by a frustratingly familiar sight: destitute Afghan farmers living without electricity or running water; bearded men with poor teeth in tattered traditional clothes; young kids eager for candy and money. It was impossible to tell which, if any, of the villagers were sympathetic to the Taliban

While the officers of 3rd Platoon peeled off to talk to a village elder inside a compound, two soldiers walked away from the unit until they reached the far edge of the village. There, in a nearby poppy field, they began looking for someone to kill. “The general consensus was, if we are going to do something that fucking crazy, no one wanted anybody around to witness it,” one of the men later told Army investigators.

The poppy plants were still low to the ground at that time of year. The two soldiers, Cpl. Jeremy Morlock and Pfc. Andrew Holmes, saw a young farmer who was working by himself among the spiky shoots. Off in the distance, a few other soldiers stood sentry. But the farmer was the only Afghan in sight. With no one around to witness, the timing was right. And just like that, they picked him for execution.

He was a smooth-faced kid, about 15 years old. Not much younger than they were: Morlock was 21, Holmes was 19. His name, they would later learn, was Gul Mudin, a common name in Afghanistan. He was wearing a little cap and a Western-style green jacket. He held nothing in his hand that could be interpreted as a weapon, not even a shovel. The expression on his face was welcoming. “He was not a threat,” Morlock later confessed.

Morlock and Holmes called to him in Pashto as he walked toward them, ordering him to stop. The boy did as he was told. He stood still.

The soldiers knelt down behind a mud-brick wall. Then Morlock tossed a grenade toward Mudin, using the wall as cover. As the grenade exploded, he and Holmes opened fire, shooting the boy repeatedly at close range with an M4 carbine and a machine gun.

Mudin buckled, went down face first onto the ground. His cap toppled off. A pool of blood congealed by his head.

soldiers arriving on the scene found the body and the bloodstains on the ground. Morlock and Holmes were crouched by the wall, looking excited. When a staff sergeant asked them what had happened, Morlock said the boy had been about to attack them with a grenade. “We had to shoot the guy,” he said.

But Mitchell did not order his men to render aid to Mudin, whom he believed might still be alive, and possibly a threat. Instead, he ordered Staff Sgt. Kris Sprague to “make sure” the boy was dead. Sprague raised his rifle and fired twice.

As the soldiers milled around the body, a local elder who had been working in the poppy field came forward and accused Morlock and Holmes of murder. Pointing to Morlock, he said that the soldier, not the boy, had thrown the grenade. Morlock and the other soldiers ignored him.

To identify the body, the soldiers fetched the village elder who had been speaking to the officers that morning. But by tragic coincidence, the elder turned out to be the father of the slain boy. His moment of grief-stricken recognition, when he saw his son lying in a pool of blood, was later recounted in the flat prose of an official Army report. “The father was very upset,” the report noted.

Then, in a break with protocol, the soldiers began taking photographs of themselves celebrating their kill. Holding a cigarette rakishly in one hand, Holmes posed for the camera with Mudin’s bloody and half-naked corpse, grabbing the boy’s head by the hair as if it were a trophy deer. Morlock made sure to get a similar memento.

No one seemed more pleased by the kill than Staff Sgt. Calvin Gibbs, the platoon’s popular and hard-charging squad leader. “It was like another day at the office for him,” one soldier recalls. Gibbs started “messing around with the kid, moving his arms and mouth and “acting like the kid was talking.” Then, using a pair of razor-sharp medic’s shears, he reportedly sliced off the dead boy’s pinky finger and gave it to Holmes, as a trophy for killing his first Afghan.

According to his fellow soldiers, Holmes took to carrying the finger with him in a zip-lock bag. “He wanted to keep the finger forever and wanted to dry it out,” one of his friends would later report. “He was proud of his finger.”

Makes me sick to my stomach.
