Lucia Perez was allegedly abducted outside her school by a gang before being drugged, repeatedly raped and penetrated with an additional object.
Some 50 activist groups are calling on women across the South American country to take to the streets dressed in black at 1pm on Wednesday to protest against the sexist culture that exists. There were "femicides" - the term written into Argentina's legal constitution to describe gender-based killings - in and at least three women have been killed in the country since Miss Perez's death.
Miss Perez is believed to have been abducted outside her school in Mar del Plata, a city miles south of capital Buenos Aires, on 8 October. Her body was brought to hospital by two men claiming she overdosed on drugs, but doctors soon noticed signs of violent sexual penetration.
Thousands took part in similar protests over violence against women in Argentina last year. You can find our Community Guidelines in full here.
