I've been interested in psychologically profiling the Delphi murderer for a while. However, this is a difficult undertaking considering the notable lack of crime scene description. So this is going to be a rather short analysis and highly speculative analysis without references to Jung nor personality typologies derived from witness description.
On February 13, 2017, Liberty German and Abigail Williams were visiting the train tracks on a day off school in Delphi, Indiana. During the course of their trek, Liberty German recorded a video using the camera of her phone of a suspicious man following them. The man recorded was a 5'6" to 5'10" heavyset male with reddish-brown hair. The man later had approached the two girls at which point an audio recording was taken where the suspect can supposedly be heard saying, "Hey guys... Down the hill". The bodies of the two girls were later found on February 14th. The case remains unsolved to this day.
Serial killers can usually be organized into six typologies each with their own unique incentive, ideas, thoughts and methods of killing. The varieties of these types are the organized killer and disorganized killer and the main types are the visionary killer, the mission-oriented killer, the hedonistic killer (thrill, lust and comfort) and the power-oriented killer.
Typology of the Delphi Killer
Typology of killers using the O/U dichotomy is near useless on its own, but it's all we really have in this scenario. The murderer was most likely of a disorganized variety with an unknown main type. It's unlikely this murder was pre-meditated because, considering the location of the crime, it'd be almost impossible to know when and where the victims would be alone in the days preceding the murder. Murderers who kill children are also more likely to have low scores across all areas of cognitive functioning, were less likely to pre-meditate their murder and were also more likely to have a history of mental illness. So, both the statistical analysis and specificities of the crime fit perfectly into the disorganized killer category.
Interestingly, a moment of insight on his main typology may come from an unexpected source. In Supt. Carter's message to the killer he stated, "we know this is about power to you", in reference to the killer's motivation. This suggests they know of a power-oriented typology. If he is power-oriented it suggests his victims fit a type, are strangers but were stalked beforehand. A power-oriented disorganized mix can be contradictory.
Sadly, we cannot speculate on his big five personality typology considering the lack of crime scene analysis and dialogue between the killer and others.
Speculation, Comparisons to Other Killers, Psychological Profile
Because of his disorganized typology, we can speculate he has a low IQ, has an impulsive personality, is odd and socially awkward, most likely lives near the location of the crime, is sexually incompetent, is highly introverted, made rituals of the bodies after, has father or mother's who's work was unstable, lives alone, was harshly disciplined as a child and is in an unskilled field of work.
From research on child murderers, we can speculate multiple traits of the killer. He most likely has low scores on all forms of cognitive functioning, has a history of mental illness, is aged nineteen to forty-two, has previous child sex abuse charges, partakes in unskilled work or is unemployed, he also most likely killed out of opportunity and actually lived in the area. The idea of him being a local in the area is interesting, considering many people believe he was a local of Delphi. This could mean he had excellent spatial memory or awareness.
Traits that carry across statistics:
-Low IQ
-Local
-Unskilled work or unemployed
From this we can assume he has extremely low conscientiousness.
The tragic case of Liberty German and Abigail Williams is one of frustration and unanswered questions. It's been four years and no closure have been provided to the family or the concerned public. All we can really do now is speculate and possibly bring to light who this criminal was in other ways.

Veggietales was an American television program on air from 1993-2015 popular for its christian themes, distinct humor and 3d animated style. Despite this, arguably the most important element of Veggietales was its easily recognizable cast of characters. So what made the design of these characters so timeless and memorable?
Color in character design is arguably one of the most important aspects in making a character easily recognizable and show the viewer who the character is. In Veggietales they use color to show the relations between characters. For example, Larry is the exact opposite on the color wheel as Bob signifying that they're supposed to be complete opposites in personality and often at odds with each other. The colors weren’t selected randomly however, color also displays the two character’s opposing personalities. Red is a passionate, dominating and angry color which correlates to Bob's powerful demeanor, common sense and anxiousness. On the other hand, Larry is an easygoing and happy character signified by his green coloration.
Another important aspect of character design is the shape of a character. Squares are usually level-headed, circles are usually strange and triangles are usually cunning. Bob on paper should be shaped mostly using squares to signify stability, but paradoxically he's shaped like a circle as to highlight the interesting contrast between his level-headedness and childish sarcasm. While still a circle, Larry is an elliptical circle which is an odd and humorous shape.
The character designs are but also have recognizable differences which them easily memorable. Bob's body is a circle with four circles for his eyes/pupils and one adaptable shape for his mouth. The uniformity and simplicity of each character’s color is also a contributing factor, not just shape. If put on a 2d grid Bob is one red and Larry is two greens, on their own they mean nothing but paired together they’re immediately recognizable.
Veggietales, accidentally or not, uses recognizable, simple shapes and colors to wordlessly tell you who the characters are and make them stick in your memory.
-Statistic-
Based on a review of 400 criminal profiles the conclusion can be reached that Scorpio is the most common star sign among serial killers, murderers, mass murderers, etc. Roughly around 10.75% of the serial killers viewed were Scorpios, followed then closely by Gemini and Capricorn. Virgo was the least likely with only 5% of the serial killers viewed being born from August 23rd to September 22nd. Interestingly, two of the serial killers viewed had the combination of a Sun in Pisces, Moon in Pisces and Ascendant in Saggitarius. This contradicts the popular belief that Sagittarius and Virgo are the most common among Serial Killers, I'd assume that this is because the most famous Serial Killers are usually either one of those signs.
This is a ranking of how common it is for a killer to be each sign:
1. Scorpio 10.75%
2. Gemini 10.25%
3. Capricorn 9.75%
4. Aries 9.25%
5. Aquarius 9.25%
6. Sagittarius 9%
7. Pisces 8.5%
8. Taurus 8.25%
9. Libra 7.75%
10. Leo 6.75%
11. Cancer 5.5%
12. Virgo 5% (Note: The number doesn't go exactly into 100% for some reason so just pretend)

@kendrixtermina Good point and something I forgot to check because I’m not smart enough to do anything you just asked. Here’s the population percentage of each MBTI type according to The Myers Briggs Foundation website compared to killers.
ISFJ (population) 13.8% - (killers) 8%
ESFJ (population) 12.3% - (killers) 4%
ISTJ (population) 11.6% - (killers) 15.33%
ISFP (population) 8.8% - (killers) 6%
ESTJ (population) 8.7% - (killers) 6.67%
ESFP (population) 8.5% - (killers) 4%
ENFP (population) 8.1% - (killers) 2.67%
ISTP (population) 5.4% - (killers) 12%
INFP (population) 4.4% - (killers) 3.33%
ESTP (population) 4.3% - (killers) 13.33%
INTP (population) 3.3% - (killers) 6%
ENTP (population) 3.2% - (killers) 4.67%
ENFJ (population) 2.5% - (killers) 0.666666666667%
INTJ (population) 2.1% - (killers) 5.33%
ENTJ (population) 1.8% - (killers) 5.33%
INFJ (population) 1.5% - (killers) 2.67%
Here’s the commonality letter wise (and yes I know functions, I’ve read both Jung and Brigg’s firsthand descriptions):
E (population) - 49.3% - (killers) 58.66%
I (population) - 50.7% - (killers) 41.34%
S (population) - 73.3% - (killers) 69.3333333333%
N (population) - 26.7% - (killers) 30.6666666667%
T (population) - 40.2% - (killers) 68.66%
F (population) - 59.8% - (killers) 31.34%
J (population) - 54.1% - (killers) 47.9966666667%
P (population) - 45.9% - (killers) 52.0033333333%
Based on an analysis of 150 criminal profiles on personality-database a conclusion can be reached that ISTJ is the most common type among serial killers. Roughly around 15.33% of the serial killers viewed are ISTJs and 23.33% are Si dominants (ISTJ and ISFJ). Interestingly, only 0.6% of killers are ENFJs.

I have an alternative blog/account titled "Beatle" for casual activities.
Audio of Zodiac killer suspect Richard Gaikowski whose voice was identified as the same as the Zodiac's by police dispatcher Nancy Slover. His voice was so similar she went as far to say "it's the same guy". https://www.zodiackiller.com/SuspectGaikowski.html
The neo-noir genre encompasses stories with a diverse set of settings and characters though often utilizing common noir tropes such as femme fatales, hard-boiled detectives and a complex murder investigation. However, an often overlooked trend in the neo-noir genre is the trope of perceived villains and a character’s realization that perception itself is the actual thing terrorizing them. Usually, using definite "truths" to who the nature of the villain to vanquish the thing terrorizing them.
Sometimes this manifests as the characters themselves fighting against the theme or law of the universe. For example, No Country for Old Men explores the absurdist belief that the universe is chaos. Both Anton Chigurh and the cop chasing him search for some kind of reasoning or truth despite there being none. The villain of Anton Chigurh is only a reflection of what's really terrorizing the cop's mind, which is the fear of a new evil rising that follows chaos. This is why he searches for answers to vanquish that fear.
Other times it manifests as a loop in the character's own psychology. In Memento the main character has short term memory loss which hinders his quest to avenge his murdered wife. In the end it's revealed that he killed the murderer years ago and he's purposefully forgetting and killing new people over and over again to give his life meaning. In the end the thing terrorizing him isn't the criminal who killed his wife but rather himself. Another example is in Drive where the main character is in a mental loop of believing the truth that his new girlfriend's murderous husband is the villain and he is the good guy. By the end, he realizes truth that he can never escape from the cyclical loop of isolation he is in and returns to being a criminal.
Introduction
Yuka Takaoka, a twenty-three-year-old Japanese woman, was arrested for attempting to murder her boyfriend with a kitchen knife on May 23rd, 2019, after she was allegedly exposed to photos of him being intimate with another woman. Stating afterward, “since I loved him so much, I just couldn’t help it”.
Speculation, Comparisons to Other Killers, Statistical Traits The motivation behind Takaoka's assault remains unclear; the only motivation surrounding the "love" she felt for him. A psychological complex common in serial killers is one of gaining control via owning the corpse of the victim. Jeffery Dahmer, an American serial killer who often dismembered and tested upon his young male victims, claimed he murdered his victims due to the fact that he believed owning his victim's bodies placed him in complete control over them, thus fulfilling a sexual fetish.
Jeffrey Dahmer claimed that killing was "the least satisfactory part... No, the killing was not the objective. I just wanted to have the person under my complete control, not having to consider their wishes, being able to keep them there as long as I wanted". Takaoka shared similar sentiments, “I thought I would kill him because I thought that was how I could be with him. I thought that expressions such as ‘I like you’ and ‘I would like to be with you’ would become a reality if [we both] die" before stating "After killing [him], I, too, wanted to die”. It seems that Takaoka's sole motive wasn't necessarily the thrill of killing her boyfriend, but rather the means to an end surrounding fulfilling the gratification of a sexual and romantic fetish surrounding complete control. The victim being a romantic partner already establishes that the perpetrator most likely felt some sort of physical attraction to the victim, strengthening the hypothesis. It is possible that the obsession was further activated by the photographs taken of the victim and the anonymous woman, which struck the perpetrator's obsession with "ownership" over the victim.
When looking more specifically at statistical analyses, it seems Takaoka does not fit the stereotypical profile of a female murderer or serial killer. Though Takaoka did know her victim, both common traits in female killers, Takaoko's motivation was not material, she waited for authorities to place her into custody, the victim was not elderly nor adolescent, nor did Takaoka kill due to physical aggression from an intimate partner.
Outro
The case of Yuka Takaoka, though tragic, highlights an important point surrounding the predictable link between killing and the need for dominance. It will most likely go down in history as one of the strangest cases of attempted murder of all time.
