I read this -What could be so bad in his life he had to end it?
“His personal problems, rumours in Kuala Lumpur said, included a split with his wife Fizah Khan, and his fury that a relative, opposition leader Anwar Ibrahim, had been given a five-year jail sentence for sodomy shortly before he boarded the plane for the flight to Beijing”
Apparently the first one is BS - his wife said that had a good marriage.
Possibly the second reason? We will most likely never know unfortunately.
But I think it’s almost beyond doubt now that he did it. The evidence is overwhelming.
