Argentine rallies for missing man

A huge campaign of marches, vigils, speeches and art is being held in Argentina, aimed at ensuring that a retired builder is not forgotten.

Julio Lopez, 78, is a name that everyone in Argentina recognises.

He disappeared two years ago after appearing as a witness in a major human rights trial.

Mr Lopez has become a symbol in the fight for justice for the atrocities committed by Argentina's military government in the 1970s and 80s.

He was a victim twice over. He was kidnapped and tortured by the authorities working for the Argentine military which governed between 1976 and 1983.

Then two years ago, he gave evidence in the trial of police chief Miguel Etchecolatz.

But the day before the policeman was sentenced to life in prison for human rights atrocities, Mr Lopez disappeared.

Unlikely hero

His family and human rights activists believe he was taken by police officers or ex-police officers as a warning to others considering testifying in subsequent human rights trials against former members of the military government.

Mr Lopez has not been seen since, despite a massive campaign of marches, rallies, media coverage and appeals from his family and the president.

To mark the second anniversary of his disappearance, a fresh round of protests has been organised in Buenos Aires and in Mr Lopez's home city of La Plata.

A large silhouette of the former building worker is being unveiled on a wall in the capital, candles are being lit and thousands are marching from the Argentine Congress to the presidential palace.

The demand is simply that Mr Lopez be found alive.

The frail, quietly spoken man has become an unlikely hero in the continuing fight in Argentina to bring to justice those responsible for the tens of thousands of people kidnapped, tortured and killed during a period that become known as the Dirty War.
