Read the following news item.
A grizzly bear that killed a mother and her baby in Yukon last fall was emaciated and desperately pursuing unusual food sources at the time of the attack, according to an investigation by the territory’s government. Valérie Théorêt, 37, and her 10-month-old daughter, Adèle Roesholt, died on Nov. 26, 2018, when a grizzly bear attacked them near their trapping cabin in the remote Einarson Lake area northeast of the village of Mayo. Gordon Hitchcock, chief conservation officer for the Government of Yukon, said the 18-year-old male grizzly bear was emaciated to the point that it was incapable of hibernation. Additionally, it was insignificant and chronic pain from having eaten a porcupine – which bears do not typically eat – and had quills penetrating its digestive system from the mouth to stomach. “This bear had started turning to uncommon food sources,” said Mr. Hitchcock, who presented findings of a necropsy in Whitehorse on Wednesday. - CNN News
