Capture of Guzmán and collapse
On September 12, 1992, Peruvian police captured Guzmán and several Shining Path leaders in an apartment above a dance studio in the Surquillo district of Lima. The police had been monitoring the apartment, as a number of suspected Shining Path militants had visited it. An inspection of the garbage of the apartment produced empty tubes of a skin cream used to treat psoriasis, a condition that Guzmán was known to have. Shortly after the raid that captured Guzmán, most of the remaining Shining Path leadership fell as well.
The capture of rebel leader Abimael Guzman left a huge leadership vacuum for the Shining Path. "There is no No. 2. There is only Presidente Gonzalo and then the party," a Shining Path political officer said at a birthday celebration for Guzman in Lurigancho prison in December 1990. "Without Presidente Gonzalo, we would have nothing."
At the same time, the Shining Path suffered embarrassing military defeats to self-defense organizations of rural campesinos — supposedly its social base. When Guzmán called for peace talks, the organization fractured into splinter groups, with some Shining Path members in favor of such talks and others opposed. Guzmán's role as the leader of the Shining Path was taken over by Óscar Ramírez, who himself was captured by Peruvian authorities in 1999. After Ramírez's capture, the group splintered, guerrilla activity diminished sharply, and peace returned to the areas where the Shining Path had been active.
