'My father, the killer'

"Did you actually kill hundreds of people, Dad?" It's not a question that many people feel the need to ask their parents. But for a group of daughters and sons in Argentina, it became one they could not ignore.

When the phone rang in Analía Kalinec's Buenos Aires home on a wintry August afternoon, she had no reason to suspect the call would end up blowing her family apart.

"It was my mum. 'Look, don't freak out but Daddy is in jail,' she told me. 'But don't worry, this is just politics.' Until that phone call, I had never ever linked my dad's job to the dictatorship. Not even remotely…"

Analía's father is Eduardo Emilio Kalinec, a former police officer who served under the brutal military junta that ruled Argentina between 1976 and 1983.

He was accused of some of the worst human rights violations in the country's recent past - over 180 cases of abduction, torture and murder committed in the regime's secret detention camps.

For the seven years it held power, the military government targeted political dissidents - communists, socialists, union leaders, students and artists. Up to 30,000 were "disappeared" after being kidnapped and illegally imprisoned by security officials like Kalinec.

But Analía hadn't got even a hint of her father's well-kept secrets until 2005, when she was 25, and received that call from her mum.

Kalinec was taken into custody and, despite his wife's initial optimism, was never released. In 2010, he was given a life sentence for crimes against humanity.
