After Charlie Kirk was fatally shot during a speech at Utah Valley University, the FBI arrested 22-year-old Tyler Robinson, alleging he carried out the political assassination from a rooftop.

But Robinson’s grandmother insists federal agents got it wrong, describing him as a “shy, quiet kid” who never owned a gun or talked politics.

Her defense clashes with investigators’ claims, which include Discord messages, surveillance footage, and tips from Robinson’s own family pointing to his involvement. While prosecutors prepare charges, the case has split public opinion—between law enforcement’s evidence and a grandmother’s unwavering belief in her grandson’s innocence.
