The attack was so violent it left the girl in a wheelchair with a severe back injury.
She identified some of her attackers, who police apprehended — only to let go after they were ordered to cut the lawn at the police station.
Several hundred marchers stopped traffic on Nairobi's Central Kenyatta Street on Thursday morning, carrying cardboard boxes representing the more than 1.2 million online signatures on a petition called "Justice for Liz." Liz is a pseudonym for the victim, who lives in Busia County.
Ngozi Nwosu, an activist from Nigeria joining the march, says she was struck by how many Kenyan men were marching.
"There are men joining women to speak against rape," she says. "In Nigeria, women are most likely [to] stand alone. Kenya is doing well in terms of standing up against injustice."
"...She was beaten, gang raped and dumped in a pit latrine. But when she identified three of her attackers to the police, their only punishment was to cut grass around the police station.
That, says Abdulmelik, "emboldens others to also rape."
The case lay idle for months. Liz's mother had to lease the family farm to afford the hospital. Then a newspaper reporter picked up the story; the activism that followed showcased a Kenya that is increasingly wired and middle class. Kenyans used Twitter and Facebook to bring media attention to the case. Ordinary Kenyans donated thousands of dollars through mobile money-transfer campaigns to pay for Liz's care.
Doctors say Liz will be able to walk again next month, thanks to back surgery. That's not enough, though, says Saida Ali, executive director of the Kenya-based Coalition on Violence Against Women..."
