"We consider ourselves fortunate this is all that happened," Osborn said. Two thousand miles away, in the suburbs of Syracuse, Bleyle department charged three 13-year-old boys with plotting to set off a homemade bomb, patterned after the Oklahoma terrorist bomb, at their junior high school. "It's scary that kids can lock themselves in their rooms and get through their computers these bomb recipes," said Bleyle. These are not isolated instances: Similar cases have been reported this year in at least a half dozen other communities, from New Hampshire and New Jersey to Florida and California. And far from the local police stations, similar worries were voiced Wednesday by President Clinton at a news conference in Tokyo, where he fretted publicly about how the Internet might aid international terrorism.

"Isn't it a concern that anybody, anywhere in the world, can pull down off the Internet the information about how to build a bomb like the (Oklahoma City) bomb?" Clinton asked at a news conference with Japanese Prime Minister Ryutaro Hashimoto. The distribution of bomb recipes over the Internet is a concern shared by local law enforcement authorities across the country. A sampling of incidents involving teen-agers, explosives and the Internet that have been reported this year: On April 14, a 16-year-old boy in Houston lost one finger and sustained hand and chest injuries when a homemade bomb exploded. Authorities said they found bomb "recipes" taken from the Internet. In Orange County, po lice 6aid four boys, aged 15 and 16, confessed last week that they crafted six acid-filled bottle bombs from information gleaned from postings on the Internet.

One of the bombs injured a 5-year-old boy ho found it on an elementary school playground. On April 4, the principal of the junior high school at Exeter, N.H., found in a school locker a pipe bomb he said was built by a 12-year-old, using an Internet posting, who then sold it to another 12-year-old for $5. Last month, custodians at a high school in Huntington Beach, found similar devices on two occasions. Police in three other southern California communities Tustin, Los Alamitos and San Cle-mente have had cases involving teen-agers building bottle bombs in recent months. Bleyle said parents should pay close attention to what children are calling up on the Internet.

liam Bleyle of the upstate New York community of Manlius, Onondaga County, have never met, but this week acknowledged that they are worried about the same computer-age phe Clinton agers who nomenon: teen-build terrorist-style The Associated Pre Prime suspect Theodore Kaczynski lived in 10-by-12 foot cabin full of clues. Analyzing them is an unglamorous part of the probe. Grunt work begins to nail Unabombar bombs by following instructions on the Internet.

After that, McQuay began his letter-writing campaign seeking help from news organizations and victims' rights groups.

When asked if his background had been investigated by the school district in 1987, McQuay told the Express-News in a recent prison interview: "I had a clean record." Court records in Leesville, however, show Larry Don McQuay, now 32; was convicted in October 1985 of stealing about $1,800 cash from a Kentucky Fried Chicken restaurant. The Vernon Parish District Court assessed a four-year probated sentence, but McQuay served his probation in San Antonio, where he was under supervision of the Bexar County Adult Probation Department. bationer at the time he left his job as a school bus driver after writing sexually suggestive letters to a Roosevelt High School student in December 1988. No official had connected McQuay the school bus driver and McQuay the probationer. McQuay was arrested Nov.

2, 1989, four days after completing probation. An indictment by a Bexar County grand jury accused him of aggravated sexual assault of a child. The charge was reduced to indecency with a child, and McQuay pleaded guilty Jan. 8, 1990, in District Court. Judge Sharon MacRae sentenced him to eight years in prison.

After reviewing McQuay's case file, MacRae said there was nothing in the record that would have alerted her to the theft conviction. A month after McQuay was sentenced in Bexar County, a Louisi the San Antonio Express-News has learned. McQuay, now being held under tight security at the South Texas Parole Violator Facility, terrified people across the nation with claims that he molested 240 children and might kill his next victim when released on parole. His belief that only surgical castration would stop his lust for sex with children horrified viewers who saw interviews with McQuay on national television in recent weeks. But McQuay doesn't mention a 1985 probated sentence for felony theft in Louisiana.

McQuay was on probation in August 1987 when he got a job driving a school bus in the North East School District. Records in Bexar County and Louisiana show McQuay was on probation the entire 16 months he drove the school bus. He was considered a model pro record in Louisiana and was on probation when he was given a reduced sentence here for molesting a young boy.

Now comes the painstaking, unglamorous laboratory work to determine with certainty whether the truckloads of evidence taken from Theodore Kaczynski's remote Montana cabin link him to the 17-year string of Unabomber attacks.

And that work likely will take weeks. Federal law enforcement officials had a lot of evidence even before agents started Combing Kaczynski's cabin. Aside from some letters and the Unabomber's manifesto published by The Washington Post and The New York Times, that evidence consisted mainly of the remains of 15 bombs that killed three people and injured 23. One of the Unabomber's explosives was defused. "What they're looking for are things which are consistent with those remnants," said John Hicks, who headed the FBI's crime lab for five years until his retirement in 1994.

Kaczynski has been charged only with possession of bomb parts and ndt with any of the Unabomber attacks. "There has been an extraordinary amount of work done over the last 17 years to analyze and look at the evidence from the crime scenes, the communications from the Unabomber and the physical evidence," said Milton Ahlerich, who succeeded Hicks until his own retirement in January. That includes such things as fingerprints and tool marks, biological examinations of such things as hair, fibers and DNA and chemical analysis of explosive residue to determine the exact composition of the bombs. There also are the quirks of the typewriter used to type the manifesto and other missives. All were typed on the same typewriter, according to a senior federal official in Washington, who said investigators believed the Unabomber had done so deliberately to give authorities a way to authenticate them.

U.S. News World Report says in tomorrow's edition that FBI crime lab experts have determined that the third typewriter removed from Kaczynski's cabin is the machine on which the manifesto and other letters were typed. In addition, law enforcement sources said FBI agents at the cabin discovered what they say is the original copy of the manifesto manuscript near that third typewriter. Agents from the FBI, the Bureau of Alcohol, Tobacco and Firearms and the Postal Inspection Service have been carefully inspecting and then removing truckloads of evidence from the 10-by-12 foot cabin, including one live bomb, one partly built explosive and parts of the cabin itself, sources said. The evidence is all being shipped back to the FBI lab in Quantico, Va.

But the agents are not simply crating up everything in sight. A federal judge this past week sealed the cabin and surrounding property for 30 days so agents can conduct repeated searches. Armed with analyses of bomb parts, some of which can take two weeks or more, agents can look for evidence not previously sought, said Terry Turchie, assistant special agent in charge of the San Francisco office's Unabomb division. One might think it shouldn't take weeks to examine such a small cabin. But when explosives are involved, any object might be a bomb ready to blow or a booby-trap.

"Despite what you see in the movies, where they call in the bomb squad and some guy goes in and cuts the wire as the music reaches a crescendo, you just don't do that," Hicks said. The first order of business is to make 'any unknown object safe. So agents brought in X-ray equipment to scan the cabin's contents. Also useful are robots that can take X-rays or move boxes away from agents. Another technique is to "put a string around it a long string and give it a yank from a distance," Hicks said.

"If it doesn't go off, then maybe you take the next step." Once the explosives are gone, agents must decide what might be evidence. Something like copper wire might seem ubiquitous, impossible to identify as belonging to one person. However, chemical testing could reveal contaminants making it unique, such as elevated levels of lead or barium, he said. The plastic insulation also might reveal unique properties. Wire cutters found at the cabin could provide more clues.

"Anytime you have any kind of mechanical action between a piece of metal and a tool, the tool can transfer marks from its cutting edge," he said, "If the tool has been sharpened, it might have grinding marks that produce fine scratches. Those imperfections in the tool would be transferred to anything it came in contact with." Despite the power of the Unabomber's explosives to maim and kill, such things as insulated wires have survived and are available for comparison with the tools and other evidence found in the cabin, he said. To see if others were in Kaczynski's cabia, agents might check for fingerprints, probably using something like a roach bomb that emits a vaporous superglue that sticks to fingerprints, Ahlerich said. Hicks sounded somewhat wistful when asked if he wished he were back at the bureau right now. "This stuff is exciting," he said.

"This is what it's all about. All these years, the frustration that developed. There is a sort of feeling like gee, I wish I could be there." B.
