Write a question about the following article.

Another car pulled up and that body was also whisked away . By this time there were about five police officers on motorcycles at the scene . One officer was vainly trying to sop up the largest pool of blood with a rag or towel . The whole episode took about two minutes . No sooner had the second body been taken away than people were again walking along the footpath , literally stepping over blood , seemingly taking no notice or perhaps too afraid to stop . No crowd of onlookers gathered and no crime scene was set up . There was no collection of evidence and any forensic evidence was being contaminated .

Question:
Why would there be police at the scene ?
Available options:
(1). There was a death ..
(2). None of the above choices ..
(3). There was an attack on the crowd via terrorism ..
(4). There was a murder ..
