The writings left behind by the shooter in Wednesday's deadly attack at a Minnesota church have many of the underpinnings of a troubled person - and just as much confusion over why the mass shooting occurred.
The suspect, Robin Westman, 23, appears to have posted at least two videos on YouTube. The first showed a multiple-page document written in English but in Cyrillic characters. The second showed a four-page document in which the shooter apologizes to family and friends and writes about feeling pain and suffering.
The rest of the video shows the shooter displaying an arsenal of weapons including a rifle, a handgun, a shotgun and several magazines of ammunition, scrawled on with a mishmash of political messages and in-jokes.
Authorities say the cryptic writings are at the forefront of a domestic terror investigation into Westman and what FBI Director Kash Patel said was anti-Catholic attack that killed two children and injured 17 others during a Catholic school Mass before committing suicide in the rear of the church.
But like with many mass shooters, Westman's motives - even with the detailed writings - will be hard to decipher into anything meaningful that could prevent future attacks. Westman is believed to have been a former student at the Annunciation Church and Catholic School in Minneapolis, but authorities say it's unclear what role that may have played.
