The bomb that killed a top advertising executive in his New Jersey home Saturday was mailed from San Francisco by an anarchist dubbed the Unabomber who is responsible for 14 other blasts over 16 years, according to the FBI. The feds also said that the bomb was mailed with a return address -- which they haven't released -- and a December 3 postmark. It exploded Saturday in the North Caldwell, N.J., home of Young & Rubicam executive Thomas Mosser. Its construction and components link it to a series of bombings dating to 1978 -- scattered throughout the country -- in which one person has died and 23 have been injured, the FBI said. Most of the bombs' components had been stamped with the letters "FC" -- short for a phrase disparaging computers. Mosser was the first victim who didn't work in the computer or airline industries, although his company had recently won the accounts of two major computer companies: Xerox and Digital. The FBI profile of the Unabomber makes him out to be a white man in his 30s or 40s with a high school education and an aversion to technology. Agents say he first lived in Chicago, then moved to Utah and California. The FBI is offering $1 million for information related to the bombings. The number: 800-701-BOMB.Post your opinion on theCrimebulletin board.
