  First at the scene
  Initial investigating
  Police action
  Notetaking

First at the scene (Homicide)

In centres where special units respond quickly to homicides, the first officer at the scene only secures the scene until they arrive.

In centres where special units are either not available or will take a long time to arrive, the first officer at the scene may investigate a homicide.

  1. Treat all deaths as homicides initially.
  2. Safety first. Determine whether a dangerous suspect is at the scene.
  3. Request assistance, if needed, in order to respond to a dangerous suspect.
  4. Secure the scene.
  5. Find out what happened.
  6. Prevent the loss of evidence.
  7. Make detailed notes.

Initial investigating (Homicide)

A special unit will usually investigate. If a special unit is unavailable, the first officer at the scene should find out what happened.

  1. Find out who discovered the body, when, and how.
  2. Find out who might be a suspect.
  3. Find out whether there is danger from a suspect.
  4. Find out who the victim is.
  5. Find out whether anyone moved the body.
  6. Find out whether the victim said anything about the homicide.
  7. Find out whether the suspect said anything about the homicide.
