LONDON , England ( CNN ) -- Previously unseen footage of Diana , Princess of Wales , taken just hours before she was killed in a car crash , has been shown to the jury at the inquest into her death . The footage showed Diana and Dodi step into an elevator at the Ritz Hotel . Images taken from a security camera at the Ritz Hotel in Paris show the 36-year-old smiling as she and her lover Dodi Fayed step into an elevator and later walk out of the hotel . Further footage shows Fayed visiting a jeweler 's shop , images that could lend support to claims that he was buying an engagement ring . Earlier , a British coroner at the inquest said tt may never be known for certain whether Princess Diana was pregnant when she died in the Paris car crash . Lord Justice Scott Baker told the jury at the inquest into the deaths of the princess and her lover Dodi Fayed that scientific evidence might be unable to demonstrate `` one way or the other '' whether she was in the early stages of pregnancy . But he said they would hear `` intimate '' details of her personal life . Watch footage of Diana 's last hours » . Baker told the 11 members of the jury -- six women and five men -- Diana may have been on the contraceptive pill and that evidence she was poised to get engaged to Dodi on the night she died was contradictory . On Tuesday the judge , who is acting as coroner in the case , told the jury that a famous image taken in summer 1997 showing Diana wearing a swimsuit could not be proof she was pregnant with Dodi 's child as she had not started a relationship with him at that stage . The jury is set to hear `` scene setting '' evidence , including CCTV and a tourist video . The inquest to establish cause of death is expected to be a six-month process . Fayed 's father , Mohammed Al Fayed , has contended from the start that Diana and his son were murdered because the royal family `` could not accept that an Egyptian Muslim could eventually be step-father to the future king of England , '' referring to Diana 's son Prince William . `` I 'm hoping for justice , '' Al Fayed said outside court . `` At last , we 're going to have a jury from ordinary people and I hope to reach the decision which I believe that my son and Princess Diana have been murdered by the royal family . '' Baker told the jury of Al Fayed 's allegations , but again reminded them that they were responsible for deciding the facts of the case , but not to assign blame or guilt . `` You have to decide four important , but limited factual questions : who the deceased were , when they came by their deaths , where they came by their deaths and how they came by their deaths , '' Baker said , according to inquest transcripts . `` The first three questions are unlikely to give rise to any difficulty . The fourth is a rather wider question and is directed towards the means by which they died . '' Diana , 36 , and 42-year-old Dodi Fayed were killed on August 31 , 1997 when the Mercedes-Benz they were traveling in hit a pillar in the Pont de l'Alma tunnel in Paris . They were being pursued at the time by the paparazzi after leaving the Ritz Hotel . Driver Henri Paul , who was also killed , was drunk and driving at high speed . Bodyguard Trevor Rees-Jones was the sole survivor . Next week , the jury is scheduled to travel to Paris to see the crash site , along the River Seine . They are also expected to hear testimony from the paparazzi who were present after the accident . In its evidence section , the Web site for the inquest has posted previously unpublished pictures taken by paparazzi of the limo before and immediately after the accident .
