On 28 April 2010, Shining Path rebels in Peru ambushed and killed a police officer and two civilians who were destroying coca plantations of Aucayacu, in the central region of Haunuco, Peru. The victims were gunned down by sniper fire coming from the thick forest as more than 200 workers were destroying coca plants. Following the attack, the Shining Path faction, based in the Upper Huallaga Valley of Peru and headed by Florindo Eleuterio Flores Hala, alias Comrade Artemio, was operating in survival mode and lost 9 of their top 10 leaders to Peruvian National Police-led capture operations. Two of the eight leaders were killed by PNP personnel during the attempted captures. The nine arrested or killed Shining Path (Upper Huallaga Valley faction) leaders include Mono (Aug. 2009), Rubén (May 2010), Izula (Oct. 2010), Sergio (Dec. 2010), Yoli/Miguel/Jorge (Jun. 2011), Gato Larry (Jun. 2011), Oscar Tigre (Aug. 2011), Vicente Roger (Aug. 2011), and Dante/Delta (Jan. 2012). This loss of leadership, coupled with a sweep of Shining Path (Upper Huallaga Valley) supporters executed by the PNP in November 2010, prompted Comrade Artemio to declare in December 2011 to several international journalists that the guerrilla war against the Peruvian Government has been lost and that his only hope was to negotiate an amnesty agreement with the Government of Peru.
