In many states, Jennifer’s estate might not pass to Fotis if he was a suspect in her death. This is certainly a very complex estate situation, and we don’t really know whether Jennifer had a separate will. I think it is possible that she did, due to the twists and turns of their relationship and pending divorce proceedings.
I’d be surprised if she didn’t draw up a will after they separated, and I’d be surprised if he did, because I don’t think he comported himself as a practical man-and because he couldn’t get Jennifer to pay for it. I think he would likely spend what he could steal from her on waterskiing, women, and trips to Greece. Not on drawing up a will which benefits him not at all.
