Why is the Major Crimes Unit investigating a homicide case?

In cases where death is not imminent, a decision must be made, usually in consultation with a Homicide Unit Supervisor, if the Homicide Unit will investigate.

The decision to investigate is generally based on the strength of evidence that suggests a victim is likely to succumb to their injuries. This information is generally provided by medical professionals and conveyed to investigative units by front line police officers.

In some circumstances, the Homicide Unit may be unavailable or tied up on other cases. In these instances, the Major Crime Unit will be assigned to investigate murder cases.

The Major Crimes Unit employs many seasoned, experienced and capable investigators.

Detectives with Major Crime experience often top candidate lists for potential assignment to the Homicide Unit during the annual spring transfer process.

In cases where death is not imminent, but possible, investigators often caution suspects for murder when they read them their rights.  If they are cautioned properly, anything they say in connection with the assault may be used against them in the event death ensues and charges are upgraded.
