Step-by-step explanation:
The first officer to respond to a suspected homicide call is generally a patrol officer arriving a short time after the call is received. The actions taken at the time of arrival may have a critical bearing on the subsequent course of the investigation. Responding officers might encounter:
1) A lurking murderer: Most at times, murderers do lurk around the crime scene in order to gather as much information as they can concerning the investigation of that crime. Other times, they stick around and pretend as if nothing had happened.
2) Weapons or evidence of murder at the crime scene: No crime leaves a clean slate. At a point, an evidence of any sort is usually discovered at the time of the crime or afterwards.
3)Crowd gathering: In any scenario involving crime, there is usually a crowd to be seen after the body of the individual had been discovered.
4) Disappearance of evidence: The essence of the murderer lurking around is to monitor police movements. The murderer might have been the one who alerted police after taking out the evidence
5) Witnesses unwillingness to partake in the investigation: Most at times, people fear that giving their statements to the police might trigger the anger of the murderer towards them thereby putting their families and themselves in danger.
