Judicial confirmation that Chilean President Salvador Allende took his own life during the military coup of Sept. 11, 1973, coincided with Tuesday's 39th anniversary of what many in Latin America have come to refer to as "the first 9/11."

Chile's first rightist administration since the restoration of democracy in 1990 did not officially mark the anniversary of Gen. Augusto Pinochet's putsch.

Young militants in the capital neighborhood of San Bernardo observed the occasion by trying to attack a police post, while other protesters set fire to barricades on 11 de septiembre avenue in the Providencia district.

Leftist parties and civic organizations offered tributes to the victims of the military regime during a ceremony at the Salvador Allende monument, opposite the presidential palace.

"My grandfather was a man consistent with his ideals. He always struggled for a more just society and I believe that that legacy is more relevant than ever," Socialist Party stalwart Maya Fernández Allende said.

"Today it is the social movements, the students, who have picked up the banner of struggle to end inequality in our country," she said.

The Santiago Court of Appeals announced Tuesday that it is formally closing the investigation began last year into Salvador Allende's death.

The probe led to the exhumation of the late president's body.

A multidisciplinary team of experts concluded that Allende killed himself with a gunshot to the head, confirming an account long accepted by his family.

The president took his own life as Pinochet's troops were storming the presidential palace following an aerial bombardment.

"The family feels content that the judiciary has been able to reaffirm what we somehow knew, but this time, scientifically," Sen. Isabel Allende said Tuesday at the monument to her father.

Relatives of some of the roughly 3,200 people killed by the 1973-1990 Pinochet regime planned to hold candlelight vigils Tuesday night at locations including the National Stadium - turned into a makeshift prison in the days following the coup - and Villa Grimaldi, a notorious torture chamber.

All but nine of the 76 officials and agents of the dictatorship convicted of human rights violations are behind bars, though they are being held in "special" prisons that are considerably more comfortable than ordinary penitentiaries.

Besides killing more than 3,200 people, the Pinochet regime jailed 38,000 others on political grounds.

The majority of political prisoners were tortured.
