Hard to say actually-the fact is that the Subcontinental mafia has very extensive interests in cricket,amongst other things.If the matches which Pakistan lost were "fixed"-then Woolmer may have threatened to spill the beans.Would have made sense bump him off.The hard reality is that some current player/officials of the Pakistani side have had previous allegations of match-fixing raised against them incl. the captain Inzamam Ul Haq,Mushtaq Ahmed.

Inzy's reputation is going downhill bigtime.His chances to be recognised as amongst Pakistan's greatest players are going the same way as Mohd Azharuddin.
The last murder (if this was one, and that’s a big if) as a result of a sporting event that I know of was Andres Escobar, the Colombian soccer player killed for scoring an own goal in the World Cup, and that was rumoured to be because organised crime lords lost a lot of gambling money on Colombia’s unexpected early exit. I had a thought that this might be a similar situation.
However, that it happened so soon after the match itself gives me big doubts, especially if Inzamam is the one getting the flak.
