Because it was all too convenient for Alex to die, it seems like murder but I can't see how anyone could have given him a pulmonary embolism.
I have given much thought to this because of the timing more than anything. I just can’t see it as a coincidence. However, LVD & CD were in Hawaii & I can’t see any way they could have killed him….unless ZP did something and I really don’t think that is the case. That leaves me thinking it may have been at his own hand. If intentional suicide then I see 3 or 4 possible reasons AC might take his own life…
1) He knew with LE having just exhumed TD’s body that it was likely that they were closing in on the murderous trio and didn’t want to face a trial and imprisonment nor could he admit to his new wife what he had done.
2) He knew that CD & LVD would make him the scapegoat and felt so betrayed by LVD after all he’d done for her that he didn’t want to live anymore.
3) CD & LVD convinced him that it was time for him to depart this life and move on to the next probation and his next mission.
4) The light bulb came on and he actually realized that he wasn’t involved in taking out zombies but in taking the lives of innocent people and especially the children and couldn’t live with himself anymore.
I know many have said that a pulmonary embolism or blood clot just formed and could have been caused by his high blood pressure and long flight as he had just returned - was it from Mexico or South America or something - I can’t remember - but long flights have been known to cause DVT which can move to the lungs and become PE.
But certain drugs can also cause DVT & PE such as cocaine or heroin and while I don’t believe either was found in his system, I don’t know how long it stays in the system or how quickly it can cause DVT - meaning what if he did one of these drugs the day before his death? Would it still show on a toxicology report? I don’t know. I also don’t know if there are other ways to cause DVT or PE but I don’t think that we can conclude that it is not possible to cause a PE to yourself or someone else.
I can’t say for sure whether AC died of natural causes or suicide but I lean more towards suicide than murder if it is one of the two and I lean more toward # 3 above for the reason he might have done that. Remember that ZP said LVD & CD were no longer calling him or answering his calls after they went to Hawaii - except that they called him the night before he died and told him TD was being exhumed and then I think AC had called CD again the day he died and asked for a blessing - not the patriarchal blessing but a blessing because he wasn’t feeling well. Then CD called ZP and told her that AC wasn’t doing well and she should go check on him. Who knows what was said in that conversation between CD & AC that day?
AC’s death is just one more thing in this case that we will likely never know the details and the truth about. There are so many things in this case we may never know! When you think about it, there are probably as many or more things we don’t know than what we do.
I’m not saying for sure it was suicide - just that I find that more likely than murder. But I don’t put more weight into that possibility than I do the natural causes theory either. The timing of it just makes me suspicious.
