Guzmán was tried by a court of hooded military judges under provisions of articles 15 and 16 of Law 25475 adopted by Fujimori's government in May 1992 after April's constitutional crisis. The reason for this was to protect the judges' lives, as Shining Path was known for brutal retaliation against judges who convicted their members. After a three-day trial, Guzmán was sentenced to life imprisonment and incarcerated at the naval base on the island of San Lorenzo off the coast of Lima.
