I’m not at all sure it even is murder, even if she deliberately withheld medical care. I’ve seen advance directives from people who would refuse care in similar circumstances, and it’s not a crime for a wife to honor such a wish. Maybe you could get her on lying to the police about it, or for a lesser crime of medical neglect, but not murder.
If you really want it to be a prosecutable murder, find her fingerprints on a bottle of the virus she poisoned him with. Take a blood sample to test for antiviral treatments she took to prevent accidently infecting herself. Maybe find her impatient boyfriend who didn’t want to wait for a divorce.



I flooded a dormitory once, but I blame building maintenance for tricking me into it.
I wake up and head to the bathroom. Turn on the shower, nothing happens. Try the sink, still no water. No advance notice to the residents, but the water must have been shut off for some reason. I have a class to go to, so I turn everything “off”, get dressed, and leave. I’d forgotten that one of the sink knobs was threaded the opposite way from the standard convention, so that one was full on when the water was restored. Came back to the dorm after lunch and realized exactly what I’d done as soon as I entered the hallway and saw the maintenance man running his shop-vac outside my room. It overflowed the sink drain, and the bathroom floor drain, flowed through the dorm room, and was in the process of flooding the hallway.
