LOS ANGELES A second batch of undisclosed records in the Oklahoma City bombing has been found in Baltimore, the ***Los Angeles Times*** reported Tuesday, prompting the FBI to issue a worldwide directive ordering all bureau field offices and attaches to comb their files for any more documents that may not have been turned over to Timothy J. McVeigh's lawyers.

In addition, ****The Times*** said new details emerged about the contents of more than 3,000 pages of documents discovered last week -- witness statements and photographs relating to a mysterious person known as Robert Jacques, as well as surveillance tapes of sightings of "John Doe No.2," an alleged McVeigh co-conspirator.

Although the government later discounted the existence of either person, rumors about their alleged association with McVeigh spawned endless theories of conspiracies and government cover-ups in what became the largest investigation in FBI history.

Federal officials last week discovered the 3,135 pages of new material after collecting McVeigh files from dozens of field offices across the country.

After turning the documents over to McVeigh's defense team and his convicted co-conspirator, Terry I. Nichols, seven additional documents turned up late last week in the Baltimore office, sources told ****The Times***.

Like the material found in other offices, however, the Baltimore documents were discounted by government sources, who said they have no relevance to McVeigh's guilt or innocence, the Los Angeles paper reported. Baltimore was one of dozens of FBI field offices involved in interviewing witnesses and collecting evidence in the case.

In issuing its sweeping order, the FBI sought to ensure that no additional materials will surface that should have long ago been shared with the defense.

"Everybody is checking again. The whole bureau today," said an FBI source, one of several government sources who asked not to be identified because of the ongoing investigation. "Everybody is going through everything again."

A Department of Justice official told ***The Times*** authorities are worried that if even more material is found after this latest search, it will be all the more embarrassing to federal law enforcement.

"We certainly want all the information that is available," the official said. "We want all the information that's out there."

The April 1995 Oklahoma City bombing was the largest terrorist attack in the United States, killing 168 people and injuring more than 500 others.

With his execution on hold and his attorneys reviewing old leads about possible accomplices, McVeigh has written a letter to the Houston Chronicle stating unequivocally that there was never a "John Doe No. 2."

Legal experts were quoted as saying the statement, in McVeigh's own distinctive handwriting, could weaken any argument his attorneys might make to seek a new trial based on the possible existence of other conspirators in the 1995 bombing of the Alfred P. Murrah building in Oklahoma City, in which 168 people were killed and hundreds injured.

McVeigh dated his single-page letter May 2 -- a full week before the FBI revealed it had found 3,135 documents about the bombing investigation that it never shared with the defense.

Many are "tips" that reportedly did not pan out from people who claimed to have seen a man with McVeigh in the days before the bombing. The suspect came to be known as "John Doe No. 2."

McVeigh's letter came in response to a reporter's inquiries about renewed allegations by his estranged trial attorney, Stephen Jones, that McVeigh has always inflated his role in the bombing to serve his ego.

Jones claims McVeigh was actually the tool of a larger group of conspirators.

"Jones has been thoroughly discredited, so I'm not going to break a sweat refuting his outlandish claims point-by-point," McVeigh wrote to the Chronicle. "The truth is on my side," according to DPA.
