The Pentagon is separately preparing a new round of punishments, including a stinging demotion of retired Lt. Gen. Philip R. Kensinger Jr., 60, according to military officials who spoke on condition of anonymity because the punishments under consideration have not been made public.

In more than four hours of questioning by the Pentagon inspector general's office in December 2006, Kensinger repeatedly contradicted other officers' testimony, and sometimes his own. He said on some 70 occasions that he did not recall something.

At one point, he said: "You've got me really scared about my brain right now. I'm really having a problem."

Tillman's mother, Mary Tillman, who has long suggested that her son was deliberately killed by his comrades, said she is still looking for answers and looks forward to the congressional hearings next week.

"Nothing is going to bring Pat back. It's about justice for Pat and justice for other soldiers. The nation has been deceived," she said.

The documents show that a doctor who autopsied Tillman's body was suspicious of the three gunshot wounds to the forehead. The doctor said he took the unusual step of calling the Army's Human Resources Command and was rebuffed. He then asked an official at the Army's Criminal Investigation Division if the CID would consider opening a criminal case.

"He said he talked to his higher headquarters and they had said no," the doctor testified.

Also according to the documents, investigators pressed officers and soldiers on a question Mrs. Tillman has been asking all along.

"Have you, at any time since this incident occurred back on April 22, 2004, have you ever received any information even rumor that Cpl. Tillman was killed by anybody within his own unit intentionally?" an investigator asked then-Capt. Richard Scott.

Scott, and others who were asked, said they were certain the shooting was accidental.

Investigators also asked soldiers and commanders whether Tillman was disliked, whether anyone was jealous of his celebrity, or if he was considered arrogant. They said Tillman was respected, admired and well-liked.

The documents also shed new light on Tillman's last moments.

It has been widely reported by the AP and others that Spc. Bryan O'Neal, who was at Tillman's side as he was killed, told investigators that Tillman was waving his arms shouting "Cease fire, friendlies, I am Pat (expletive) Tillman, damn it!" again and again.

But the latest documents give a different account from a chaplain who debriefed the entire unit days after Tillman was killed.

The chaplain said that O'Neal told him he was hugging the ground at Tillman's side, "crying out to God, help us. And Tillman says to him, `Would you shut your (expletive) mouth? God's not going to help you; you need to do something for yourself, you sniveling ..."
