text:  Hello, you're listening to the BBC World Service. I'm Matt Pintus and this is Sporting Witness. It's been 30 years since the murder of footballer Andres Escobar, who was shot dead just days after Colombia's shock exit from the 1994 World Cup. To mark the anniversary, I've been delving into the BBC World Service archives. You'll hear from one of Escobar's closest friends, taken from interviews with Witness History and World Football.
