If the OP wishes to overreact and change hotels, it could be an optional good customer service gesture to give a refund for the unused nights, assuming that the guest advised hotel management of the plan to leave and the reasons. It could also be a good customer service gesture to give some small something to those who temporarily changed rooms after the murder/suicide. However, I understand from the OP that these guests were away from the hotel during the time when people were temporarily relocated in other rooms, so that this inconveneince would not have affected the OP. I also understand from the OP that the guest just moved to the Hilton without advising the hotel of this fact so that the room could be released for other guests, so no refund is due here, nor should the first hotel pay anything toward the Hilton stay.

Assuming that the OP ultimately does pay for the Starwood stay, since the OP did arrive and stay the first night, it wouldn't necessarily be wrong to give points and nights credit for the entire paid period as hotels don't always monitor departure times and sometimes give additional credit for stays when there has been an early departure, but this is a YMMV situation and the award of such points and nights credit should not be SPG policy.
