Does the sensationalism of the murder make the crimes more palatable to the public, meaning, do people only begin to care when there are multiple victims/a serial killer may be involved?

Prompt: Does the sensationalism of the murder (the fact that four bodies are found at once in one location followed by the discovery of several body parts nearby soon after) make the crimes more palatable to the public, meaning, do people only begin to care when there are multiple victims/a serial killer may be involved? Why?
