The scenario is this: in the midst of a pandemic, the husband is found dead in his own bedroom but there are no physical scars on his body (autopsy confirmed that he succumbed to Pneumonia) however the wife kept insisting "he died from the virus" as an excuse. She states: "I went to the pharmacy to buy him meds and booked an appointment with our physician as my hubby isn't feeling well" to confirm her words: one must contact both to verify her story if she really was there or if she made an appointment with the doctor.
Investigators called the clinic and they said she made no apppointment and the pharmacy stated a woman fitting her description never went there. Does that make her a liar? Did she neglect her husband for a long time that he passed away? Her defense is that "the virus claimed his life, like it has done to countless people" but the coroners result conflict her statements. Did she use the pandemic as a guise to commit a "perfect murder"? It's because this virus is affecting people's respiratory system.
Now for the legal challenge of proving she intends to murder her husband: she uses the situation of "worldwide pandemic" as a cover up of killing someone as she knows Pneumonia and this "virus" (i.e. similar to COVID) share viral patterns or symptoms alike. "Shortness of breath" for example, is also present in Pneumonia. She might have disguised murder as a homicide sensationalizing off the pandemic by putting on the facade of "my husband died of COVID" (whilst pretending to sob & mourn) towards media outlets.
The real breakthrough is her husband's last will & testament is found and disclosed, so does that serve as intent to murder (for his inheritance money)? As she knows that it has a large amount (8 figure sum) being passed down to a beneficiary after death. The "intent" to murder in this case is closer to neglect (she could've taken care of him but chose to ignore his illness and failed to mention it to doctors) whilst using a pandemic as a cover up framing it on the media as if he died from the virus (but that's not the truth).
Having the will in hand alone is circumstancial, to prove she willingly murdered her husband for his money: one has to have the lawyer (or witness who saw her at the law firm) confirm if she made frequent visits with them whilst he's on the death bed dying in pain.
