What devastating news does the narrator receive when she reaches the hospital in Chapter 25?

The narrator ends up running to the hospital because she cannot find a cab. When she gets there, she is given the news that the old man had died at 6:52 p.m. The hospital staff ask her if the old man had sustained any type of injury that would have led to the brain hemorrhage that killed him, and she realizes that the damage he had sustained during the earthquake had been even more severe than she had feared.
