I know where the Columbine connection comes from, but where did you hear that he took inspiration from/interest in the others?

He was part of online true crime communities. My guess is in regards to ISIS, he was probably fascinated by their terrorist attacks. Also in regards to Onoprienko, he was interested in serial killers in addition to school and mass shooters, and probably based on his geographical location, its sorta no wonder he would be interested in him, since Ukraine was his birth country, IIRC he was also into other Ukrainian and Russian serial killers like
Alexander Pichushkin, Andrei Chikatilo, the Dnepropetrovsk Maniacs, etc.

Alek Minassian (he mentioned hating feminism when he talked to police and played the song “Alek Minassian” by Egg White in his car).

He was probably inspired by other far right shooters but I don’t know exactly which ones.

Pretty sure he also looked up to Breivik

Anders Behring Breivik:
-Timothy McVeigh (From what I've researched I think he took inspiration from him mainly for the bombing of the Government Quarter)
-Theodore Kaczynski (Plagiarized parts of his manifesto)

These are the only ones I know of

Morio Tanimoto:
-Shinji Aoba

Bob Smith (Rose-Mar College Shooting) - Richard Speck, Charles Whitman

Randy Stair
- Ricardo Lopez

Ricardo Lopez
- Unabomber

And it's not a criminal, but he was Influenced by Casey Heynes too

I was looking through the investigative report on Kauhajoki, and it would seem Matti Saari also researched Red Lake/Jeff Weise and Northern Illinois University/Steven Kazmierczak

I'm not sure whether he was influenced by him or not, but Jake Davison knew about Nikolas Cruz.

For what it's worth, this is what the FBI BAU had to say about that hypothesis.

Adam was undoubtedly influenced by previous shooters in some way (and some investigators believe that he was focused on trying to learn from their techniques and mistakes) but ultimately, the BAU didn't seem convinced that he was trying to "outscore" anyone, as it had been reported early on after his spreadsheet was discovered. Despite some early statements in the media suggesting that it was a "scorecard" of sorts, Adam described the spreadsheet as a research tool to assist in "answering statistical questions."

The absence of evidence does not definitively prove that he did not view the attack as a competition but this is what they said in their summary.

Edit: Here's a useful document that covers the subject of the thread.

I love seeing how inefficient and generative government investigations are. so be it. the less they know the reality, the better.

I tentatively agree but I am curious as to what you find wrong with the FBI report cited specifically.

Pekka was not influenced by columbine. and the FBI may be everything people believe it to be, but that's about it. they will never really understand what is behind the attacks and will never be able to stop them.

just as they never managed to discover the Crazy Writer.

Tavallisen ihmiskunnan on luettava vihollisensa, yritettävä hallita heitä. köyhiä heitä, sillä he eivät koskaan tee sitä. nykyajan ihmiskunnan vihollisia suojellaan ja niitä käsitellään.

Tobias Rathjen was supposedly obsessed with David Ali Sonboly

David Copeland: Eric Rudolph

Juraj Krajčík: Brenton Tarrant, John Earnest, Payton Gendron

Ryan Palmeter:

Timothy McVeigh
Anders Breivik
Seung-Hui Cho

Nikolas Cruz searched up "mcdonalds mass shooting", so he knew about James Huberty/San Ysidro
He also searched up "massacure in hotel" (No idea if he trying to search up the 2008 Mumbai Attacks or just for mass shootings at hotels in general?), "poly tech massacre" (Ecole Polytechnique),"L.A killing rampage" (could be anyones guess as to what he was looking for), "las vegas shooting" so he knew about Stephen Paddock

Kosta Kecmanovic:
Timur Bekmansurov
Columbine (more than likely yes)

There’s no logical reason Adam Lanza wouldn’t have wanted to outscore the other shooters. He undoubtedly, if you again look at the manner how he carried out the shooting, was trying to kill just about as many as possible. It was actually a pretty large elementary school by all accounts, and the fact that he kind of targeted women and children specifically was likely both an ideological decision and a tactical choice so he could kill them more easily. General rule in shootings: shooting women and children is easier and more fun.

Tim Kretschmer researched Erfurt and Emsdetten

Salvador Ramos looked up information on the 2022 Buffalo shooting shortly before his attack. However, there's no real evidence suggesting that Ramos was inspired by Gendron in any way.

Yevgeny Manyurov was obsessed with Brenton Tarrant and Atomwaffen.

seeing what he did and how he shot up the school and even had a hitlist of names

Thomas Crooks reportedly looked up information about Ethan Crumbley and the prosecution of Crumbley's parents for not securing the gun he used in shooting.

Saint Alejandro Galaviz: Guilherme Taucci, Timur Bekmansurov and Matii Saari

Orlando Harris wrote the following names in his journal:

Stephen Paddack (one of his primary influences)
Omar Mateen
Seung-Hui Cho
Adam Lanza
Devin Patrick Kelley
George Hennard
Patrick Crusius (or curtius, sic)
James Huberty
Salvador Ramos (theorized by some as his other biggest influence)
Nikolas Cruz
Eric Harris & Dylan Klebold (obviously)
James Holmes
Robert Bowers
Payton Gendron
Dylann Roof

The last 2 are espescially interesting of him to include, considering he was black. Maybe he hated other black people? Though this is probably obviously the case since he hated his former school, where the majority of the student body is over 70% black

As for if he researched the cases online and showed interest or if he listed them for the sake of wanting to compare himself to the deadlist mass shooters in US history, it still isn't clear. Although he did write "after seeing what happened in vegas" and wrote down "hellfire trigger" in a checklist of weapons and gear he would need for the attack on CVPA, Salvador Ramos used a hellfire trigger during at Robb Elementary; so I'm of the opinion he may have actually done some research, as for the scale of which we don't know, but maybe we'll find out when the police report is released
