Argentina President Cristina Fernandez has asked for the full involvement of of federal and Buenos Aires police in finding the person who killed transgender and LGBT activist Diana Sacayan.

Sacayan's body was found in an apartment in Buenos Aires on Tuesday. It is believed she had been stabbed to death.

Fernandez spoke from the city of Garin. She personally presented Sacayan with the first identification document in Argentina to indicate a gender change.

In homage to a woman, Diana Sacayan, who was the first to whom I presented her new ID, I request the cooperation of the federal and metropolitan police to clarify this crime.

--President Fernandez

Some 1,731 transgender people have been killed in Latin America between 2008 and 2014, 78 percent of the worldwide total, the activist group Transgender Europe said.

President Fernandez was joined in her plea by Amnesty International.

A dark cloud has set over Argentina's trans community.

--Mariela Belski, Executive Director of Amnesty International Argentina

Ms. Sacayan's is the third violent transgender death in Argentina in the past month. Ms Sacayan's death followed the killings of Marcela Chocobar and Coty Olmos, two transgender women whose bodies were found over the last month in the provinces of Santa Fe and Santa Cruz.

Unless this latest wave of murders is effectively investigated and those responsible taken to justice, a message will be sent that attacking trans women is actually ok.
