Nothing really. Just having the people who were there was important. One thing I DID notice was the people who were NOT there (at smaller funerals). Not really offensive, but people whom we thought might be impacted yet did not attend. They certainly had their reasons.
So as far as attending, I say DO IT. Do the usual condolences. If it's a traditional funeral, you would have likely been sitting with the family. Considering the circumstances, you may not be asked to sit with them. Just know that could be the case. Otherwise, respectful distance but not "back of the bus".
Take an invite to sit up close if given. Again, just respectful to the family and to W's "space" issues.
