Are you impliying that he was murdered, or committed suicide?

I think it's totally plausible he died in a weightlifting accident (spotters are thing for a reason [1]). Accidents of all kinds happen frequently, so logically an accident of some kind will occasionally happen to someone involved in a corruption case.

[1] "When the chest and upper-extremity muscles fatigue, there is the risk of the barbell and weights coming to rest on the neck or chest of the lifter. Once this happens, the person may suffer fatal traumatic asphyxia, either due to compression of the airway, neck vasculature, or chest muscles of respiration."
