Programme in the Peruvian Andes. At the time of her death, in addition to her aid work, Norgrove was working towards an MBA from the University of Warwick through distance learning. She worked in Afghanistan for the United Nations from 2005 to 2008, and as regional director of an international development company based in Jalalabad beginning in February 2010. She also worked in Laos as an environmental specialist for the UN in 2008–09, Mexico and Uganda where Norgrove researched the effects of national park management on the indigenous population near Mount Elgon National Park. Kidnapping On 26 September 2010, Norgrove and three Afghan colleagues were travelling in the Chawkay District (also known as Tsawkay and Sawkay) of eastern Kunar Province when they were kidnapped by local insurgents.
