Help to find the lost citizen (Vampyr)

I killed Joe Peterson, now his son is considered to be lost Harry Peterson, one time I found a character from the dispensary, the girl who considered herself a vampire, after I killed the guy with a charred face, she was lost, I ran in Whitechapel, and saved her from the rocks, and she returned to the hospital the next night, and Harry I can't find no where, this young shit, and even sick, and feel you will die the next night, who knows where you can find it????
