20 years since '93 World Trade bombing

Relatives and survivors marked the 20th anniversary Tuesday of the 1993 bombing of the World Trade Center in New York. Edward Smith, whose wife Monica was one of four people who died, told ABC News.com he couldn't continue to live there after her death but makes a trip to New York every February for a memorial. "There were too many reminders. It was too much," Smith said. Smith's wife was eight months pregnant with their first child and about to begin her maternity leave when terrorists detonated a truck bomb in the building's parking garage on Feb. 26, 1993. In addition to the four people who died, some 1,000 were injured by the blast. Peter Goldmark, who had retired form his job at the Port Authority when the bombing occurred, said he had set up a task force to look into terrorist threats at the end of his time in office. However, he said, his successor dismantled his antiterrorist initiatives that included shutting down parking at the center. "One of the things we recommended and were going to do would have prevented the '93 bombings," Goldmark said. He added his "heart went cold" when he heard about the bombing.
