I think it was also the plotline of an episode of the AD POLICE anime OVA. Or maybe it was Parasite Dolls, which is part of the same series. I can’t remember fully.
EDIT: After looking it up, it was either EP1/EP2 of AD POLICE FILES, or EP1 of Parasite Dolls that had a plotline like this. However, prostitutes and murder have been in crime and investigation stories since the dawn of crime, probably because the correlation of the two crimes is very high in real life. Most famous example being Jack the Ripper’s cases.
