The mother of one of the victims of Iranian serial killer Mohammad Bijeh cries in memory of her dead son at Bijeh's hanging in the town of Pakdasht, south of Tehran March 16, 2005. Dubbed the 'vampire of the Tehran desert' by local media, Bijeh was sentenced to death for killing 17 children, most of them young boys he raped first, and three adults. He began to prey on children more than two years ago but the killings did not come to light because many victims were from illegal refugee families from neighbouring Afghanistan who were afraid to come forward.
