This is "Tati" Caviglia, who was murdered three weeks ago.
I didn't know her, but I know a lot of people who did. Their grief is part of the reason it upsets me more than a report of a faraway murder usually would.
There are two suspects, one of whom has already returned from his flight and given interviews, but doesn't appear to be under arrest (although I have some trouble making sense of the relevant news reports, lacking any familiarity with the normal operations of the justice system in Argentina, so I could be wrong about that). In an interview with a local newspaper he accused the other suspect of the murder, here quoted by a TV journalist:
Crimen de "Tati": El empleado Ezequiel Blanco cuenta que el otro acusado Joel Baez le dijo: "¿que onda esta vieja?. ¿Está sola?".— Mauro Szeta (@mauroszeta) September 12, 2016
Or in English: "[Her] employee Ezequiel Blanco recounts that the other suspect Joel Baez said to him 'what's up with this old woman? Is she alone?'"
It's not clear to me what, if anything, he has said to the police, although his lawyers have been on TV.
So it seems there were two young men, doing jobs in her house, at least one of whom decided that he had the right to violently destroy her body, that body that was moving so beautifully on the beat, but only belonged to an old woman who didn't matter, so she couldn't live in it any more, and that if he put it in a suitcase and set fire to it some distance away, and then went to Bolivia, no one who mattered would notice and the consequences of his other thefts from her would be less, rather than more.
I repeat: one of them says that the other one checked that she didn't belong to anyone who mattered; that he wasn't taking her life from anyone but her.
I may be looking in the wrong places, but I'm only seeing "find this person" tweets from her many friends, not the police. This picture only shows the witness already interviewed:

The news reports do not explain what efforts are being made to find him. As someone brought up on Crimewatch this seems weird to me, but I have no information about how these things are normally done and a few seconds' thought makes it obvious that it is much easier to be a permanent fugitive anywhere in South America than it is here. I just had to talk about this before I could talk about anything else. So for now I'll leave it at that.#TiempodeSanJuan #JusticiaporTati— Tiempo de San Juan (@tiempodesanjuan) September 14, 2016
