The massive search fur a missing Sannich woman today failed to turn up any trace of the 20-year-old University of Victoria student. Marguerite Tellesford disappeared last Sunday shortly after she started out for an early morning run. Police believe she was the victim of foul play. Her ear muffs and a pool of blood were found about a kilometer from her home. Barry Bell has more on the story.
Hundreds of people turned up after police called for volunteers to comb the wooded parkland of Mount Douglas, north of Victoria, for clues in the suspected murder of Marguerite Tellesford. But four hours of painstaking probing left the searchers empty-handed. Sannich Emergency Program coordinator Lance Olmstead says the effort by the volunteers was remarkable. Absolutely outstanding. We ended up in the end with almost three hundred people in this search. In this area 90% of the ground has been covered at least once. But Mr. Olmstead says searchers found no clues or evidence in what the

[单项选择]Last month the National Health Service (NHS) in England calculated its carbon footprint as the equivalent of 21m tonnes of carbon dioxide a year—just short of the amount emitted by the Drax coal-fired power station in Yorkshire, Western Europe’s largest. Unlike the power station’s emissions, though, those of the health service have been increasing: they have grown by half since 1990. Other countries fare no better. A study published in the Journal of the American Medical Association estimates that America’s health-care industry accounts for 8% of the country’s greenhouse gas emissions. In Germany, a study by the Viamedica Foundation showed that a hospital’s energy expenditure per bed was roughly the same as that of three newly built homes.
