The murder of two young Argentinian women and a girl whose torture by suspected drug traffickers was livestreamed on a private Instagram group has sent shock waves through a country unused to such extreme levels of narco violence.

Brenda del Castillo, 20, Morena Verdi, 20, and Lara Gutiérrez, 15, went missing on Friday, after they were lured to a house in the outskirts of Buenos Aires by a promise that they would be paid US $300 for taking part in a “sex party”.
