JS may be the primary focus of the recent disclosures by Kevin Donovan, but he is only part of the picture IMO.
If BS did curtail or possibly threaten to curtail funding for his son's ventures, I have to say that in addition to JS, Adam P. appears, IMO, based on what has come out, to be an individual that appears to have motive, and is someone that requires investigation by LE. It is interesting to me that BS evidently became quite upset at the suggestion by JS that AP could be part of some kind of succession arrangement at Apotex. I wonder if perhaps BS viewed JS as being controlled by or unduly influenced by AP in some way? Or perhaps he had doubts or concerns about him? If funding of the JS/AP venture(s) was threatened in some way, the murders would be a way to get around this. Of course, I have no knowledge, JMO, but I hope LE is chasing this angle down. Others comments?
