Mark Minnie, who co-authored a book about an alleged apartheid-era paedophile ring, feared for his life once the book came out, it was reported on Tuesday.
The ex-policeman was found dead with an apparent gunshot wound to the head at a friend's house in Theescombe‚ Port Elizabeth on Monday evening.
Writing in the Daily Maverick, journalist Marianne Thamm said Minnie told her he feared for his life as a result of the investigation.
“During my meeting with him in Cape Town last year he informed me that he feared for his life and that the book would stir a hornets’ nest. He also said that those who had done the bidding of the former government were still around and had never been called to account‚” she wrote.
Thamm wrote the foreword to the book, The Lost Boys of Bird Island, which Minnie penned with investigative journalist Chris Steyn. The book claims that members of the ring would abduct or pay street children and fly them by helicopter to Bird Island‚ where they were abused.
