Neda Agha-Soltan was the young Iranian woman whose death in anti-government protests in Teheran last month galvanized the opposition.
She was killed on June 20 and within hours video footage of her death sped around the world and has now been seen by millions.
Now her mother, Hajar Rostami Motlagh, has told Newshour she is waiting for her daughter's killer to be arrested and brought to justice.
It is the first interview she has given for an English-speaking audience since Neda was killed.
