STAGING:
"Staging a scene occurs when the perpetrator purposely alters the crime scene to mislead the authorities and/or redirect the investigation. Staging is a conscious criminal action on the part of an offender to thwart an investigation.
In my experience investigating suspicious deaths I have oftentimes had a 'gut' feeling that something was amiss. Practically speaking, 'If you have a gut feeling that something is wrong. Then guess what? Something is wrong.' Actually, that "gut" feeling is your subconscious reaction to the presentation, which should alert you to the possibility that, 'Things are not always what they appear to be'" This position is consistent with equivocal death investigations.
EQUIVOCAL DEATH INVESTIGATIONS
"Equivocal death investigations are those inquiries that are open to interpretation. There may be two or more meanings and the case may present as either a homicide or a suicide depending upon the circumstances. The facts are purposefully vague or misleading as in the case of a "staged crime scene." Or, the death is suspicious or questionable based upon what is presented to the authorities. The deaths may resemble homicides or suicides, accidents or naturals. They are open to interpretation pending further information of the facts, the victimology, and the circumstances of the event."²
