On Saturday it was cleared for publication that Ashraf Hanaisha, 24, a Palestinian affiliated with the Islamic Jihad, confessed and reenacted the murder.
Angelo Frammartino, 24, arrived in Israel at the beginning of the month as a volunteer on behalf of an organization promoting human rights and worked to establish a summer camp for Palestinian children in the Old City in Jerusalem.
He was stabbed to death two days before he had planned to return to his country.
According to suspicions, Hanaisha accidentally stabbed the Italian volunteer, and was in fact planning to hurt a Jew. He escaped, leaving the knife at the scene of the attack, on Sultan Suleiman Street, near Herod's Gate.
'His message was greater than anything else'
Frammartino's father, Michelangelo, said in response that he felt no hatred toward the man who killed his son, the website of the Italian newspaper Corriere della Sear reported.
According to the father, "Angelo was working to promote peace. The message he sought to convey is greater than anything else."
Michelangelo Frammartino added that "the circumstances confirm that Angelo was a victim of the war, of the injustice in the world. When we are talking about a situation of tension, absence of common sense dominates. I do not feel hatred because Angelo's thought, the principles that always motivated him, were definitely not of hatred or revenge."
In a letter sent by Angelo Frammartino to a local newspaper several months ago, the young man expressed his outlook on life: "We must face the fact that a situation of no violence is a luxury in many parts of the world, but we do not seek to avoid legitimate acts of defense."
"I never dreamed of condemning resistance, the blood of the Vietnamese, the blood of the people who were under colonialist occupation or the blood of the young Palestinians from the first intifada," he said.
