contributions from a NOW deceased donor/member in reporting

Hi all! - I am trying to figure out how to make sure ALL contributions made on a particular appeal since the beginning of the fiscal year are included in my reporting. I am missing gifts from people who have passed away since they made their gift and whose records have been marked deactivated. Not all of these people had a death date added to their records, so I am trying to figure out a way to capture them. Any advice? I am pulling the gift data through list manager. Thanks! - Elizabeth
