Just as an example that if one Googles something, they can usually find something which supports their theory, I found this very interesting article when I googled "staged burglary, rape, and murder":
'Staging is a conscious effort by the offender to mask the true motive for the crime by altering the crime scene to suggest
false motives. The offender's goal in staging a crime scene is
to misdirect the investigation and conceal his involvement in the crime.'
--------------------------
'The
minimal amount of property damage done while "ransacking" the house is noteworthy because of its inconsistency with the homicide. The offender engaged in
overkill in his assault on Marilyn Sheppard, but appeared to be generally careful in handling the property of his victims. This type of care is consistent with someone who had an overriding proprietary interest in these items. Another key indicator that contradicts the hypothesis that this was a "for-profit" burglary is that
nothing of any great value has been taken from the scene. The only evidence of anything being taken from the property is Dr. Sheppard's report of thirty to fifty dollars allegedly missing from his wallet.'
-------------------------
'Burglars rarely take the time to stack some drawers, selectively dump the contents of other drawers or search a wallet at a crime scene as was done at this scene. The reason is that it is
too high risk an environment, especially when the crime scene is a murder scene.'
-------------------------
'It is more likely that an offender motivated to commit a for-profit or drug-related burglary would have
taken Dr. Sheppard's wallet and medical bag from the scene and searched them later, when
he could do so safely and thoroughly.'
------------------------
'"The dishevelment of the house appears to be more a
cover than a quest for valuables, as the worthless things taken tend to indicate.
No burglar would hit a woman 25-35 times. He would run away."'
------------------------
'The body of Marilyn Sheppard was found on her bed in the early morning hours of July 4, 1954. Subsequent investigation revealed that her pajama top had been unbuttoned and
pushed up exposing her breasts and that one pant leg of her pajama bottoms had been pulled off of her leg'
------------------------
'In a sex crime the offender exposes the victim's breasts so that he may physically fondle and manipulate them. The presence of blood on her torso, but
the lack of blood on her breasts reveals an offender who only wanted to expose her breasts, but not touch, fondle or manipulate them.'
------------------------
'There is also inconsistent behavioral evidence in that if this was a sexually violent offender who engaged in
overkill to subdue his victim it is most likely that the sexually violent behavior would have continued unabated and he would have ripped the victim's clothing off, and brutally raped her leaving clear evidence of vaginal and anal trauma. '
------------------------
'It was also of importance to the killer to display the victim and stage the crime scene to imply a sexual motivation for the crime.'
------------------------
'It would be logical to expect a secondary transfer of blood from his fingers and hands to the telephone. No blood was detected on either the telephone or on Dr. Sheppard's fingers, hands, or person in spite of the fact that Dr. Sheppard testified that he did not wash or clean up.'
------------------------
'One must conclude that the most logical explanation for the lack of blood on Dr. Sheppard's pants and wallet, as well as on his watch, keys and ring and the green bag in which these three items were found is that these items were not handled by anyone with bloody hands.'
------------------------
'Crime scenes are
high-risk environments and none more so than a homicide scene. Offenders typically
spend no more time than necessary at a crime scene for fear of being interrupted or caught. Consequently there is a
high degree of correlation between the amount of time an offender spends at a crime scene and the offender's familiarity and comfortability at that scene. The more time an offender spends at a crime scene the higher the probability that the offender is comfortable and familiar with that scene.
Offenders who spend a great deal of time at a crime scene often have a legitimate reason for being at the scene and therefore are not worried about being interrupted or found at the scene.'
------------------------
' It was a crime in which the offender took a good deal of time to stage the scene to imply these motives.
The amount of time spent staging this scene not only reveals how comfortable and familiar the offender was, but also indicates how important it was for the offender to mask the true motive for the crime. As in all staged homicides, this offender realized that
if he did not stage the scene in some way he would immediately become a primary suspect. The offender displayed his lack of criminal sophistication by offering multiple, feebly staged pseudo-motives for this crime.'
-----------------------
'When a crime scene is staged the responsible person is not someone who just happens upon the victim. It is
almost always someone who had some kind of association or relationship with the victim.'
-----------------------
'This offender
will further attempt to steer the investigation away from him by his conduct when in contact with law enforcement. Thus, investigators should never eliminate a suspect solely on the grounds of that person's overly cooperative or distraught behavior.'
---------------------
'First, did the subject
take inappropriate items from the crime scene if burglary appears to be the motive? Second,
did the point of entry make sense; and third, did the perpetration of this crime
pose a high risk to the offender?'
--------------------
'Forensic red flags indicating staging include excessive trauma beyond that necessary to cause death
(overkill). The victim (not money or goods) is the primary focus of the offender. This type of offender may attempt to stage a sexual or domestic homicide to
appear motivated by criminal enterprise. This does not imply that personal-type assaults never happen during the commission of a property crime, but usually the criminal enterprise offender prefers a quick clean kill that reduces his time at the scene. Any forensic red flags, after careful analysis, should be placed in context with victimology and crime scene information.
When an offender stages a domestic homicide, he frequently plans and maneuvers a third-party discovery of the victim. The offender often will manipulate the victim's discovery by a neighbor or family member or will be conveniently elsewhere when the victim is discovered.' [iv]
----------------
'Inappropriate items taken from the crime scene if burglary appeared to be the motive.':
'In effect, nothing of value was taken from the crime scene.'
'Did the point of entry make sense?':
'not a logical point of entry....it would make no sense to break in a basement door when the ground floor doors were unlocked.'
'Did the perpetration of this crime pose a high risk to the offender?':
'This high-risk approach is very uncommon for rapists, who are usually cowardly by nature. If an alleged intruder was in the house to burglarize or rape, he was doing so at great risk for detection.'
----------------
'Excessive trauma beyond that necessary to cause death (Overkill)':
'35 injuries were noted on the autopsy report. The cause of death was listed as multiple impacts to the head and face with comminuted fractures of skull and separation of frontal suture, bilateral subdural hemorrhages, diffuse bilateral subarachnoid hemorrhages and contusions of the brain. The number and severity of these injuries can reasonably be considered overkill'
'The offender will often manipulate the victims discovery by a neighbor or family member'
'Dr. Sheppard called his neighbors, Mr. and Mrs. Houk, and asked them to come to the house stating, I think theyve killed Marilyn. Once Mr. and Mrs. Houk arrived, Dr. Sheppard remained downstairs and they went upstairs where they discovered her body. Although Dr. Sheppard testified that he had discovered his wifes body on two separate occasions he never called the police. Instead he called his neighbors who, once they discovered the body, called the police.'
'The murder weapon, fingerprints and other evidentiary items often removed'
'The murder weapon was removed from the scene and no latent fingerprints of value were developed.'
'The crime scene often involves the victim's or offender's residence, as the offender typically has control of the scene and therefore can spend time staging the scene without worry of being interrupted.'
'The victim's residence was the crime scene.'
'Death may appear to have occurred in the context of another criminal activity such as a robbery or rape.'
'The offender staged the scene to make Marilyn Sheppard's death appear as though it occurred in the context of a failed sexual assault or a burglary.'
'An offender who has a close relationship with his victim will often only partially remove the victim's clothing (e.g. pants pulled down, shirt or dress pulled up, etc.) He rarely leaves the victim nude.'
'The victim's pajamas were only partially removed as her pajama bottoms were pulled off one leg and her top was unbuttoned and pushed up over her breasts.'
'The offender frequently positions the victim to infer that a sexual assault has occurred.'
'The offender exposed the victim's breasts, pulled off one pant leg and slightly spread her legs implying that the victim was the target of a sexual assault.'
I note that a reference is John Douglas' work, so he should really brush up on his own work before he makes statements which directly refute the work he himself has established.
