It was early October and Wanja Mwaura, 32, was on her way to the market in Lower Kabaete, not far from Nairobi, when she heard someone shout out her name.
She looked up and was surprised to see a tall man with bulging eyes, an emaciated frame, dirtied black overalls and an equally stained thick woollen hat, sitting on the side of the road. She did not recognise him.
But when Patrick "Hinga" Wanjiru, 34, introduced himself, Wanja says she found herself in shock. Standing before her was a friend she had known since she was seven years old.
"Patrick, or Hinga as we called him, and I had met at primary school in 1992," says Wanja, who is a nurse from Kiambu County, just outside the Kenyan capital.
"Hinga used to be a great soccer player all throughout school. We nicknamed him 'Pele'."
