It will be intense for him for a few days in California because of the trauma, so let him have time with his family to grieve. As soon as the funeral is over and he has
said goodbye to his remaining family members, he'll be on the first plane back to you
if he loves you.

In the meantime, keep the apartment in excelent condition awaiting his return and
take care of yourself, as well. He will need quiet comfort and good food, and gentle care for several months following this episode in his life. Be there for him if you
love him and know that he may experience some moods of quietness when he just
doesn't want to talk too much or to be too lively. That's natural.

Take care.
