The callous bullet case engravings allegedly made by Charlie Kirk shooting suspect Tyler Robinson included a reference to Bella Ciao - an anti-fascist anthem featured in a Netflix crime drama.
The song, which emerged as a resistance anthem against fascism in 20th century Italy and in recent years gained popularity thanks to Spanish series Money Heist, offers clues as to Robinson's beliefs and potential motive in the shooting.
The 22-year-old was turned in and arrested on Thursday after the fatal shooting of conservative influencers Kirk at his 'American Comeback Tour' event at Utah Valley University.
Kirk was shot in the neck at the event during a debate with a student about mass shootings, with horrifying footage showing him recoiling from the impact before he was later pronounced dead.
At a press conference on Friday, Utah Governor Spencer Cox revealed the bullets Robinson allegedly loaded, with one shot at Kirk, were engraved with disturbing slogans.
