Documents found in suitcases owned by Kevin Mulcahy, a former CIA technician found dead this week on the porch of a rented cottage in rural Virginia, included papers bearing the CIA letterhead, according to the sheriff's deputy who made a rapid check of the contents before turning them over to the FBI.

The deputy, Gary Dalton of the Shenandoah County Sheriff's Department, said that local investigators did not read the CIA documents found in three of Mulcahy's suitcases.

The documents, except for one legal pad on which Mulcahy had "made some serious notes" about assassinations, appeared to be "old records, frayed and bent," he said. "There were old newspaper clippings, too. And tape recordings."

Preliminary reports indicate that Mulcahy, who was scheduled to testify in the trial next month of Edwin Wilson, a former CIA agent charged with conspiracy to murder and with selling explosives to Libya, died of exposure and complications of existing health problems.

The Justice Department confirmed yesterday that Mulcahy, at his own request, was not part of the federal government's program to protect witnesses. John Russell, a Justice Department spokesman, said that Mulcahy could have been given protection if he had wanted it.

Dalton said that his department's first telephone call after finding the body was to a Fairfax doctor whose business card was in Mulcahy's wallet. After the doctor confirmed that he had treated Mulcahy and said Mulcahy told him he used to work for the CIA, Dalton said, the sheriff's department did not read the documents further.

The suitcases were given to the Winchester field office of the FBI on Monday. The FBI would not comment yesterday on the contents of the suitcases or the current location of the material. The CIA has declined any comment on the matter.

The local investigation into Mulcahy's death progressed yesterday when two women who had visited him a few days before his death contacted police.

The two women, who apparently were the only visitors to Mulcahy's rented cottage at the Mountain View Motor Court, were natives of the area "who never saw him before that day," said Dalton. The women reportedly were interested in renting the cottage, he said.

The women contacted the sheriff's department through a third party yesterday and are scheduled to be interviewed by police today. "They're scared," said Dalton. "They want their names kept quiet."

Preliminary autopsy results showed that the former CIA communications expert was suffering from bronchial pneumonia and emphysema.

Testing of the body's tissues, organs and fluids continued yesterday at the Fairfax County medical examiner's office. A spokesman for medical examiner James C. Beyer said that no results were available for release.

Further testing is being done by the FBI laboratory in Washington on Mulcahy's possessions found in the cabin and in his pickup truck, including a dozen empty wine bottles, a 12-gauge shotgun, his toothpaste, shaving cream and a bottle of Tylenol tablets. The items were driven to the the FBI lab by the local sheriff's department, which requested the laboratory's aid, said FBI spokesman Calvin Schishido.

"There's no official investigation," said Schishido. "We're just doing some investigating to see if there's any crime within our jurisdiction."

Funeral services for Mulcahy, 39, will be held at 10:30 a.m. today at Holy Spirit Church in Annandale. The body will be shipped to Brockton, Mass., for burial Saturday morning in a family plot in Calvary Cemetery.
