Here's the correct excerpt from the transcript of the BBC report on Zimbabwes youth "training" camps.

One day during the filming, I phoned a girl who we had interviewed the day before and I got her voicemail.

In her message she had a sweet voice, high pitched and gentle like that of an innocent teenager.

In fact she had helped beat to death an old lady with a walking stick.
