Ethics of Using Victim's Name in Research? What are the ethical considerations of using a victim of a violent crime's name in my research?

I understand confidentiality is not an issue as the individual is deceased. Moreover, their death was a high-profile legal case, so it's already a public issue. So while I may be "allowed" to use their name - I am more concerned about what is most respectful of their family/friends. (I think contacting them to ask would be inappropriate).

Would it be better to simply say "the deceased" or "the victim"? What if the details of the case study make it abundantly clear to whom I am referring?

EDIT 1:

To clarify, the case is high profile enough to have a Wikipedia page and have been reported in all major news outlets. None of my data is not already in the public domain.
Journalists I have spoken to have emphasized the importance of communicating in private, with ample lead time prior to publication, with multiple people with relevant personal and professional experience. For instance, if it was a suicide, you might want to run a question like this by both professionals in areas related to suicide, and families of people who have committed suicide.

Maybe this is an approach your IRB is already taking, but I see no harm in doing some investigation of your own. If nothing else, it might inform your communication with your IRB.

No "rule of thumb" will cover all situations, and the number of overlapping considerations can make it pretty complex. Communicate with people who have experience and expertise that will make them likely to think of things you might miss.
