Mohammadyeh, nicknamed "the youngest" by the press, was represented by Leif Silbersky. It was established that the other three suspects were friends, and although Mohammadyeh had wanted to become friends with two of them, he was afraid of Kaveh. Silbersky asked for Mohammadyeh to be acquitted, as in his opinion thought Mohammadyeh should not be held legally responsible for his passivity. The court of appeals, however, considered it proven that the four "had mutually agreed to ruin the party by starting a fire", and that it was of "decisive importance with regards to the question of guilt that it had not been possible to prove that no other person or persons than Kaveh had torn the paper or started the fire in the stairway." Professor Christian Diesen is of the opinion that it is possible that Mohammadyeh had "become involved in a sequence of events he had no control over and would have been judged differently if the fire had not had such devastating consequences." The penalties can be seen as low in international comparison, but Swedish law at the time had maximum 8 years prison for aged 18–20 (10 years (now 18 years) or lifetime for aged 21+) which was given to the leader. Those under 18 are given prison only for severe violent crimes, max 4 years.
