Rangers and wildlife biologists continue their investigation into the fatal bear attack that occurred the Thursday before last. The body of 59-year old John Wallace of Chassell, Michigan, was discovered on Friday, August 26th, along the Mary Mountain Trail. The investigation and autopsy results confirm that Wallace had died the previous day of traumatic injuries suffered in a grizzly bear attack. Daily reconnaissance flights over the area have resulted in very few bear sightings. The three bear traps previously set out in the area have been moved to different locations, and five additional traps have been deployed in an attempt to capture grizzlies in the area. Results of DNA tests of hair samples taken from the attack site and from any bears that may be captured in the area will aid the ongoing investigation into the circumstances surrounding this fatal attack. Yellowstone hosts over three million visitors a year, with an average of just one bear caused human injury a year. This is the second fatal bear attack in park this year and only the seventh in the park since it was established in 1872.
