If a murderer targets a specific subgroup of the population I think this information should be in the article or even in the headline. We had a murderer targeting shop owners of Turkish origin only (once he made a mistake and killed a Greek origin shop owner). The information that the victim was a Turkish origin shop owner was a necessary information in those cases and gave a warning to the targeted group.

We should not even discuss that prostitutes may not be murdered (raped, assaulted, robbed, cheated), we should take it as granted.
