Investigations revealed that during Ramadan, on 12 August 2011, Biari and Zofran plotted to attack Israeli security forces and civilian Jewish Israelis near the al-Aqsa mosque in Jerusalem. To this end, they purchased two knives and rode to Jerusalem on a public bus, staying at the Al-Aqsa Mosque on the Temple Mount for two weeks. However, according to Biari, Zofran told him that after speaking with a cleric at al-Aqsa he had decided to go back to Jaffa and become a martyr there. According to Biari, before leaving Jerusalem, Zofran borrowed Biari's cellphone and recorded a short film of himself that was intended for his parents. Biari stated that he had deleted the footage from his cellphone.
