Further to my last, I'm a tad cautious about the contact: a background check implies he's in his early 40s, far younger than Diane seemed to be, and unless anyone actually knows what their relationship actually was, I'd be cautious about taking it quite for granted, because there are aspects of his life which may explain his comments about estrangement. It's even possible he may not be aware of her decease, so I'm going to check with the hospital chaplains anyway, just to be on the safe side.
