Investigators later uncovered chilling evidence pointing to a calculated and ideologically driven act. They found bullet casings near the scene and at a wooded area where the weapon—a bolt-action rifle—was stashed. Several of the casings bore bizarre and disturbing inscriptions that reflected both mockery and political messaging.

Among the inscriptions were phrases such as “notices bulges OWO what’s this?” and “if you read this you are gay lmao,” showcasing Robinson’s use of internet meme culture in a violent context. Other messages had clearer political connotations, including “hey fascist! catch!” accompanied by etched arrows, and “oh bella ciao, bella ciao, bella ciao ciao ciao,” referencing an Italian anti-fascist anthem.

Robinson’s Discord messages further revealed the extent of the planning. He discussed retrieving the rifle from a drop site, hiding it wrapped in a towel, and changing clothes to avoid detection. These details were confirmed by evidence recovered at the crime scene and during the investigation.

Authorities believe Robinson acted alone and was motivated by ideological opposition to Kirk’s political stance. He is currently in custody and faces multiple charges, including aggravated murder.
