It's 8:48 on Tuesday morning, two weeks to the minute that the first hijacked jet crashed into the World Trade Center. At Ground Zero, where more than 6,000 people are still missing, the solemn search for any sign of life goes on. But even this vital work must stop to remember the thousands who are lost somewhere in these mountains of debris. Assistant Fire Chief Frank Fellini has been at Ground Zero since the first hours of the attack. "Almost everyone knew someone. I've met five or six firefighter fathers looking for sons and sons looking for their fathers." 48 Hours was granted unprecedented access to both Ground Zero and the command center of New York's Office of Emergency Management. An army of 20,000 city, state and federal workers as well as volunteers are on the front lines, carefully sifting through debris.

Like all new mothers, Eviva Dubin, a 31-year-old New Yorker, wants her 8-week-old baby, Harrison, to have everything he could possibly need. So Harrison has his very own gas mask, as does every member of the family. Dubin also is stockpiling antibiotics, all as protection against a chemical or biological terrorist attack. “I think it can be seen as hysterically humorous. I think it can seem extreme,” Dubin tells 48 Hours Correspondent Susan Spencer.“But in the event of a chemical or biological emergency, I don’t want to wait for the Feds to send in the antibiotics and masks to get help. I don’t feel like waiting on line with my child and husband for a mask; it might be too late by then.”

For more than 30 years, Jocko Marcellino and Screamin' Scott Simon have made a living acting like their idols: doo-wop singers from the 1950s . They are the founders of Sha Na Na, the musical group with the grease and the goofy hit television show in the '70s. "They're not the latest hits, but they're the greatest hits," Simon says of the songs the group popularizes. "We're not stars. We didn't write the songs; we didn't sing the original hits." Nevertheless, the group built itself up into headliners, the most memorable of which was probably John "Bowzer" Bauman. Famous for a pose in which he simultaneously flexes a muscle and opens his mouth, Bowzer was that kind of greasy but intensely vulnerable character that really did exist in the '60s and in the '50s. Bowzer and the others are in their 50s now, and their music lives on. Sha Na Na sold millions of records, but they never had a hit of their own. They would interpret the hits of others; in a sense, they were the great pretenders. But it was all in fun, at least until one day, when a greaser with a great voice showed up in Florida fooled a lot of people. Danny C. was not just a great pretender; he was a great imposter, reports Correspondent Bill Lagattuta for 48 Hours.. Nothing seemed to stop Gerald Barnes, not even three more arrests and convictions for medical fraud. He didn't just lie to patients and doctors. He lied to his five wives.

Gerald Barnes:What drove this personable, smart man to deceive so many people? One psychiatrist who examined him called him "immature, extremely insecure... and depressed." But Barnes claims he was only interested in helping others.

For the last week, Americans have been following the dramatic story of twin baby girls from Guatemala, joined at the head -- until a daring, 22-hour operation by neurosurgeons in California separated them. The prognosis for both is cautiously optimistic. Correspondent Jane Clayson reports on another amazing story of conjoined twins. From the time she was a little girl, Emily Stark says she knew that twins were in her future. When she became pregnant in November, 2000, an ultrasound verified her premonition: she was carrying twins. Then she had another hunch: that they were joined. Doctors confirmed that she was right about that too. At first, the Starks were devastated. But the twins were joined at the base of the spine and did not share any internal organs, which greatly improved their chances for survival. The Starks decided to keep the babies. Two months before the due date, Emily went into labor and delivered her twin girls, Alexandra and Sydney. After the birth ot the twins Sydney and Lexi, the Starks decided to separate the girls. But the surgery carried the risk of paralysis. Could the team of doctors succeed?

When Bob Angleton pulled into his driveway on a Thursday evening in April of 1997, he knew something bad had happened. "As I pulled up into my spot, I noticed the back door was open," he tells 48 Hours. "Now I was concerned." Bob had begun to worry earlier that evening when his wife, Doris, didn't show up at their twin daughters' softball game. Bob, the team's coach, phoned and paged her but she didn't answer. After the game, Bob drove 12-year-olds Niki and Ali straight home. By then, even the girls were worried. "We were all worried; we didn't know where she was," says Ali. "We needed to find where she was," adds Niki. When he found the side door open, Bob didn't go inside. Instead, he backed out the driveway and called 911. Minutes later, police officers arrived, and entered the house. One of them came out and broke the news to Bob. "He came out, walked up to me, looked me in the eyes and said, 'Was your wife wearing a white shirt?' The message was clear, it was clear to me," Bob recalls. Doris Angleton's body was found lying in the hallway next to the kitchen. She'd been shot seven times in the face, five times in the chest. "My legs buckled," Bob says. "He (the officer) grabbed me and he held me up and said, 'Look, you got to be strong for your daughters; you gotta be strong for your kids. Stand up, stand up.' " As hard as it was to tell the girls what had happened, it was next to impossible to explain why it had happened, why anyone would want to kill Doris Angleton.
