Remembering A Princess

Britain's royal family attended a special church service Monday near Balmoral Castle in Scotland to mark the first anniversary of the death of Diana, Princess of Wales, CBS News Senior European Correspondent Tom Fenton reports.

Looking somber and wearing black ties, Prince William, 16, and Prince Harry, 13, prayed for their mother alongside their father, Prince Charles, at Crathie Church, where the family worships during its Balmoral holidays. The service was also attended by Britain's prime minister, Tony Blair, and his wife, Cherie.

The Royal family, spending the weekend at their Balmoral retreat, on Sunday expressed their gratitude after receiving many messages of sympathy.

A spokesman for Queen Elizabeth said: "The Queen and the Royal Family, particularly the Prince of Wales, Prince William, and Prince Harry, would like to thank people for their messages and kind gestures of sympathy at this sad time and for sharing their remembrance of the Princess of Wales."

The royal family insisted on making the anniversary of Diana's death in a Paris car crash on Aug. 31 last year a "private affair" in contrast to the outpouring of public emotion that marked the princess's funeral.

Visitors are coming to Kensington Palace, her former London home, where they are also leaving flowers and messages. The number of mourners is way down compared to last year. Many are tourists.

"We would like to express how special she was," one visitor said.

"No, we haven't forgotten. She's very much in our minds," said another.

One woman said that Diana represented someone who cared about everyone, someone who everyone felt as if they knew, even if they had not met her.

Flags are being flown in Britain at half-staff as an official mourning.

Mohammed Al Fayed, father of Diana's boyfriend who also died in the crash, unveiled a memorial at his London store, the famous Harrod's. The opulent bronze fountain is intended to be a permanent Diana and Dodi shrine.

"I believe that anyone who looks upon this memorial will find comfort and peace," Fayed said.

Diana is gone and the deep grief is gone, but she certainly hasn't been forgotten.

He can now look forward to inheriting the throne some day, perhaps even with his mistress, Camilla Parker-Bowles, at his side.

Meanwhile, the investigation into the crash that killed Diana has been long and complicated, reports CBS News Correspondent Vicki Mabrey.

In Paris, where Diana died, there is a restrained remembrance of the princess. While the faithful are still coming to the site of the fatal crash, there are fewer of them.

On Monday morning, an out-of-work American actor sang a mournful song to the princess. There are no official French commemorations - only a small crowd gathered to pay tribute at the exact time that Diana's Mercedes crashed one year ago.

An artist who has created a Barbie-doll-like Diana candle burned 36 of them for the 36 years of Diana's brief life.

There are more police and journalists at the site than visitors. The mood is summed up by two British women who came to Paris to mark the anniversary.

"She has gone," one woman says. "We have to accept it, but I don't think we should forget her."

As for the investigation into the crash, it's still not complete one year later.

The investigating judges continue interviewing witnesses, trying to find out what caused the Mercedes, driven by Ritz hotel security man Henri Paul, to clip the 13th pillar of the Place de L'Alma Tunnel, then spin around and crash into the opposite wall.

They are still waiting for the technical analysis of the Mercedes itself, which sources say won't be ready until at least October. Some are saying there won't be a final report until as early as next year.

However, it seems unlikely that anything will change the initial speculation, that speeding and a drunk driver killed Princess Diana.
