Pathologists who examined the bodies of those slain in the Fort Hood rampage are expected to resume testifying at the trial of the accused gunman.
So far, doctors who examined seven of the 13 killed have described how some showed signs that they were shot while lying on the floor of a medical building at Fort Hood in November 2009.
Maj. Nidal Hasan is accused of opening fire on unarmed soldiers. He faces the death penalty if convicted.
After a frenetic four days in which more than 60 people testified, the pace has slowed as prosecutors call investigators and experts to describe how Hasan carried out the shooting.
Hasan acknowledges the evidence against him shows he was the shooter and has put up a minimal defense.
