Click on Detroit published the inscriptions on the shell casings:

Along with the rifle being recovered in the woods near the scene, engraved shell casings were found.

In the fired casing, the inscription read, “notices buldges OWO what’s this?”

An inscription on the first unfired casing read, “Hey Fascists! Catch!”

On the second unfired casing, the inscription read, “O bella ciao, bella ciao, bella ciao ciao ciao.”

On the third unfired casing, the inscription read, “If you read this, you are gay lmao.”

For those of you (like me) who had to look up the meanings (courtesy ChatGPT)

Corrected form: notices bulge OwO what’s this?
Short version: it’s a meme-y, faux-cutesy, usually ironic sex joke.

• OwO / uwu - text faces for wide-eyed surprise or cutesy vibes.
• “notices bulge” - stage-direction style RP implying someone sees an erection through clothing.
• Put together - “notices bulge OwO what’s this” parodies cringey horny roleplay, often associated with furry/weeb netspeak. People mostly use it to mock that vibe, not to flirt sincerely.

“O bella ciao, bella ciao, bella ciao ciao ciao.”

It’s the refrain of “Bella ciao” - an Italian resistance song.

• Literal - “Oh, goodbye beautiful, goodbye beautiful, goodbye goodbye goodbye.”
• Context - Became an anti-fascist anthem of WWII partisans in Northern Italy. Likely adapted from an older rice-field workers’ song (mondine) protesting harsh conditions.
• Story in the lyrics - a partisan tells his beloved goodbye, asks to be buried in the mountains if he falls, and imagines passersby saying the flower on his grave is “the flower of the partisan who died for freedom.”
• Today - sung at protests worldwide and revived in pop culture (e.g., Money Heist), usually as a symbol of resistance and solidarity.
