ANSWER
Mr Chairman at the time Joe was still a very sensitive, identified source from the outside, working specifically with Captain Jan Coetzee of Westrand Security Branch, whom together with Major Kruger recruited Joe whilst being a waiting trial prisoner in a criminal case in the Krugersdorp prison in late 1979, I think July.   At that stage Joe was still working closely, he only came to Vlakplaas together with Captain Jan Coetzee permanently in February 1982, two months after I've left the farm and Captain Jan Coetzee took over the farm as Commander.
