Gray explained that Kirk was answering a question about mass shootings involving transgender individuals when Robinson fired a shot that struck him in the neck.

The bullet narrowly missed several bystanders, including children close to the stage.

Kirk collapsed immediately and was later pronounced dead in the hospital.

Robinson’s mother told investigators that her son had become more political in recent years, leaning left and supporting gay and transgender rights.

She also disclosed that he was dating his roommate, “a biological male who was transitioning genders, according to the filings.

Gray stated, “On the evening of September 11, 2025, as law enforcement continued their investigation, Tyler James Robinson went to the Washington County sheriff’s office with his parents and a family friend to turn himself in. Robinson’s mother stated the following to police: On September 11, 2025, the day after the shooting, Robinson’s mother saw the photo of the shooter in the news and thought the shooter looked like her son.

“Robinson’s mother called her son and asked him where he was. He said he was at home sick and that he had also been at home sick on September 10. Robinson’s mother expressed concern to her husband that the suspect shooter looked like Robinson. Robinson’s father agreed.”

Describing the killing as “an American tragedy,” Gray said Kirk was murdered while engaging in “the free exchange of ideas, the bedrock of our democratic republic.”

FBI Director Kash Patel told a Senate hearing that investigators are probing more than 20 people who were in an online chat with Robinson.

Robinson has been charged with aggravated murder, obstruction of justice, witness tampering, and discharging a firearm in the presence of children. He remains in custody without bail.
