Sgt.'s DNA, clothing matches blood at shootings


JOINT BASE LEWIS-McCHORD, Wash. — Army Staff Sgt. Robert Bales was covered in blood when he walked back to his base in southern Afghanistan after a nighttime attack during which 16 civilians were killed.

Samples from his clothing have been matched with blood found at the scene of the shootings, an Army investigator testified Thursday.

Christine Trapolsi, a DNA analyst at the U.S. Army Criminal Investigative Laboratory, said she identified the blood of four people on various parts of Bales’ pants, shirt, boxer shorts, gloves, boots and weapons.

The blood of one woman was found both on Bales and in the blood-spattered home of Mohammed Wazir in the village of Najiban, where 11 people died.

Five other people died elsewhere.

The testimony at Thursday’s preliminary hearing for Bales in a military courtroom was technical but crucial: Although Army investigators could not take samples from the bodies of the victims to establish positive links between them and their killer, the DNA evidence appeared to establish that Bales was at the scene of the killings.

A fiber expert also testified that five different kinds of fibers found on Bales’ clothing were also found on a pillowcase at Wazir’s home.

There was a less-conclusive similarity found between fibers from the clothing of some of the five people who sought treatment for injuries sustained in the attacks — some of which were of a distinctive fiber type normally found in South Asia, but not in the United States — and a fiber found on Bales’ glove, said the analyst, Larry Peterson, who also works for the Army crime lab.

Both “have a construction that you would not see in textile materials” in the U.S., Peterson said. But, he added, “they do not match.”

The Army investigation was hampered by a three-week delay in reaching the scenes of the March 11 shootings because of safety concerns, and by Afghan villagers’ refusal to allow the victims to be examined before burial.
