because the killer left 3 signatures and this points to a seasoned killer, I feel like it is unlikely
that this is some friend of a friend...not impossible, but I think the nature of the crime suggests something else...Serials tend to avoid murdering people in their own circle or associated to as they want to avoid being discovered.
mOO
Snipped and bolded by me...regarding the bolded part, how do you know that leaving three signatures equals a "seasoned" killer? Are you trying to say that serial offenders leave no signatures on their first crime, one signature in their second murder, two in their third, and so on? Because that's definitely not how investigators view signatures...I think it is an incorrect assumption that signatures equal criminal experience.
Signatures are not defined by whether or not they occur in series. They are only defined as outward manifestations of the inner psychological urge that led to the crime. Take this example:
Charles Albright is believed to be the murderer of at least three women in Texas in the early 90s. He had an early fascination with violence and his mother took some of the small animals he killed to a taxidermist. He developed a fixation on taxidermy, especially the removal of the eyes. He killed his victims, who were sex workers, by beating and shooting them. He also removed their eyes.
Removing their eyes was not in any way necessary to kill them. He did that for his own pleasure and it was a clear reflection of a fantasy or a psychological urge that likely grew out of documented experiences in his troubled childhood. So my question is, has he been caught after the first victim, would we not call the eye removal a signature? Or would we recognize it for what it was, the personation of his fantasy in the crime? Yes, this feature of the killings did ultimately link all three of his murders as the work of one extremely evil and disturbed man, but that does not mean that in the first killing it wasn't a signature.
I'm also thinking of the killer Roger Kibbe. He had several signatures, and used them even on his first crime in the series (tying the victim with a particular type of cord that was special to him, cutting their clothing, and cutting their hair).
I've mentioned Jessica Ridgway's killer here before. He only committed one murder because he was caught fairly quickly but he performed several signatures in his first attempt: hair cutting, re-dressing, souvenir taking, and inserting a cross in the victim's remains. He later tried to say the cross part was re-direction but investigators were able to show that the cross had direct ties to the psychological reasons that he decided to kill. So if you looked at all the signatures this offender left and claimed they had to be the work of an experienced killer, you might have overlooked the teenage suspect who actually committed the crime.
The more I think about the Delphi case, the more I question the idea that he was experienced. IMO the only highly correlated conclusion we can draw from signatures is that the offender is driven by psychosexual urges and is highly likely to seek out more experiences in which to express those urges, i.e. offend again.
