"What I saw most was his eyes," Gray said. "He was staring right at me and his eyes were big and round and he looked wild - like he was in a frenzy. When I saw his eyes, he scared me."

Malvo was then brought into the courtroom again. Gray asked Malvo to turn to his left side, and Gray began crying. "That's him," he said, burying his face in his hands. "Oh God, oh Lord."

Gray's chase came after someone had shot two clerks at the ABC liquor store. One, Claudine Parker, died from her wounds. The other, Kellie Adams, was shot under her ear and had her jaw shattered, but she survived and was able to testify yesterday that she felt as though she had been struck by lightning.

"I was on the ground within three or four seconds," Adams testified in a whisper through a tracheotomy tube. "I felt this huge knot in the back of my head, and I moved my head to the left and that's when I saw all of this blood."

She also saw the legs of her assailant as he ran by her. She said they were the legs of a black man, and she gave a description that matched Gray's.

Also yesterday, prosecutors explained to the jury how Muhammad came into possession of the blue 1990 Chevrolet Caprice that allegedly became a key tool in the sniper spree. The owner of Sure Shot Auto Sales in Trenton, N.J., said he sold the car to Muhammad on Sept. 9, 2002.

The man, Chris Okupski, gave conflicting accounts of the sale. First he testified that Muhammad was actually lying down in the trunk - a chilling suggestion given that authorities believe many of the sniper shots were fired by a person lying in a prone position in the trunk of that vehicle.

But under cross-examination, Okupski said he only saw Muhammad leaning into the trunk of the car, with his feet firmly planted on the ground. He also testified that when he sold the car to Muhammad, it did not have the tinted windows or gunport cut into trunk that authorities found when they seized it last fall.

Back on the job

Muhammad's attorneys, back on the job, made numerous objections yesterday and won several of them. They persuaded the judge to bar the testimony of a ballistics expert and crime scene reconstruction expert who were expected to help bolster the case that Muhammad's Caprice was at the liquor store shooting scene in Brandywine.

Defense lawyer Peter D. Greenspun said that for the last several days Muhammad had been reconsidering his decision to represent himself, and he indicated that early yesterday Muhammad received an extra nudge from the judge.

"He decided to allow us to begin again our representation of him," Greenspun said outside the courthouse. "We're relieved and pleased he took that step and glad we have the opportunity to be in this."

But even as Muhammad's trial got back on track yesterday, it appeared that the Malvo trial may be postponed. That trial is scheduled to start Nov. 10. But prosecutors yesterday asked the judge in the case for a delay so they can prepare for Malvo's recently claimed insanity defense.

A hearing on that request is scheduled for this afternoon.
