‘I just need my son’: the people who disappeared amid Colombia’s protests

Seventy-seven people have vanished since the start of the unrest in late April - some protesters, others not linked to the demonstrations

Before 17-year-old Duvan Barros left his home in a downtrodden neighbourhood in Bogota to attend an anti-poverty demonstration, he asked his mother, Dolores Barros, to make him a fruit juice. She said no, but there would be one waiting when he got back.

That was 5 June, and Barros hasn't seen him since.
