On 12 February 2012, Comrade Artemio was found badly wounded after a clash with troops in a remote jungle region of Peru. President Ollanta Humala said the capture of Artemio marked the defeat of the Shining Path in the Alto Huallaga valley – a center of cocaine production. President Humala has stated that he would now step up the fight against the remaining bands of Shining Path rebels in the Ene-Apurímac valley. Walter Diaz, the lead candidate to succeed Artemio, was captured on 3 March, further ensuring the disintegration of the Alto Huallaga valley faction. On 3 April 2012, Jaime Arenas Caviedes, a senior leader in the group's remnants in Alto Huallaga Valley who was also regarded to be the leading candidate to succeed Artemio following Diaz's arrest, was captured. After Caviedes, alias "Braulio", was captured, Humala declared that the Shining Path was now unable to operate in the Alto Huallaga Valley. Shining Path rebels carried out an attack on three helicopters being used by an international gas pipeline consortium on 7 October, in the central region of Cusco. According to the military Joint Command spokesman, Col. Alejandro Lujan, no one was kidnapped or injured during the attack. The capture of Artemio effectively ended the war between Shining Path and the Government of Peru.
