That is why the head, Mohammad Mohammadi Gilani, and the prosecutor of the Revolutionary Court, Asadullah Lajurdi, attended the prison and held a court hearing in the courtyard of Evin. Mohammad Kechoi brought several prisoners from the Mojahedin organization to the Evin prison grounds and put them next to the pool so that they could be tried there again. Kazem Afjeei, a member of the People’s Mojahedin Organization of Iran who was serving time in prison at the time, assassinated Mohammad Kechoi with a handgun on July 8, 1360. On the last day, Kechui and Lajordi suspect him and take his machine gun from him. But he assassinated Mohammad Kechui by shooting a few bullets and getting hold of a waist weapon.
