Why did Noxolo die?

I got this from Amnesty International:

Dear Tracy,

"Noxolo was loved for being a mother, friend, soccer player and activist, she will never be forgotten by her loved-ones."
- Ekurhuleni Pride Organizing Committee Colleagues

Why did she die?

Noxolo Nogwaza was murdered on her way home from a night out with friends. In the early hours of April 24, 2011, her attacker(s) raped, repeatedly beat and stabbed the 24 year-old—apparently because of her sexual orientation.  Noxolo was an activist for lesbian, gay, bisexual, transgender and intersex (LGBTI) rights in South Africa.

A year after her death, no progress has been made in the investigation into her murder and her killer(s) remain at large. Help change that. Demand justice for Noxolo.

She was a member of the Ekurhuleni Pride Organizing Committee, an organization that aims to empower and inform LGBTI people and to combat hate crimes, victimization and injustice through education and awareness-raising activities.

Sadly, homophobia and hate crimes against LGBTI individuals are common in South Africa, particularly against those living in townships and rural areas. Definitive statistics are difficult to obtain as the South African government does not classify rapes according to sexual orientation.  However, in the last five years, there have been at least 10 reported cases of rape followed by murder of lesbians in townships across the country.

South African authorities must urgently take steps to put an end to these crimes. With your help, we can make sure that they do.

Please take action now. Tell the Police Commissioner to thoroughly investigate Noxolo's death and bring her killer(s) to justice.
