Human rights activist Hebert Marin was shot twice in the head last October. His tortured body was dumped in the gutter near his home in Cali, southern Colombia. His family believes he was killed by the police or the army. But this family tragedy is only one of thousands that have occurred in the last few years in Colombia, almost unnoticed by the outside world. Trade unionists, priests, civil rights workers, even prostitutes - all are at risk from death squads.
Tonight his brothers and sister, now exiles in Britain, take over the Open Space slot to give their view of an ugly and brutal aspect of Colombian society.

Open Space is the programme where the public can make programmes under their own editorial control with help from the Community Programme Unit.
