Photographer who took haunting shot of trapped girl with black eyes explains why he didn't try and save her

The photographer who took a harrowing image of a young girl who died after her home was destroyed by a natural disaster explained why he didn't try to save her.

The volcanic eruption of the Nevado del Ruiz in 1985 triggered significant landslides and mudflows that caused destruction in the Colombian town of Armero and the surrounding area.

Thousands of people died, among them a 13-year-old girl named Omayra Sánchez Garzón, who became the face of the disaster after photographer Frank Fournier took a picture of her trapped with only her head and hands above water.

The image of the teenager staring back at the camera with eyes so bloodshot they appeared to be black left a haunting impression on those who saw it.
