The alleged killer of right-wing activist Charlie Kirk appeared to take responsibility for the shooting on the messaging platform Discord, a company spokesperson has confirmed.
According to the spokesperson, Tyler Robinson, 22, messaged friends in a chat on Discord hours before he was arrested last week in connection with Kirk's shooting at an event at Utah Valley University.
It was me at UVU yesterday. im sorry for all of this, reads a message from an account that allegedly belongs to Robinson, according to the spokesperson and a law enforcement source.
Robinson, who has not yet been formally charged, is due to appear in court on Tuesday.
Arrested on suspicion of aggravated murder, felony discharge of a firearm and obstruction of justice, he could face the death penalty.
The Discord messages which are said to be from Robinson were first reported by the Washington Post and are thought to have been written and posted towards the end of a manhunt for Kirk's killer that lasted more than a day.
Charlie Kirk, 31, who was a controversial figure in US politics and a trusted ally of President Donald Trump, was speaking at Utah Valley University on Wednesday at an open-air event held by Turning Point USA - the organisation he co-founded - when he was hit in the neck by a single bullet.
The killing of the popular social media personality sparked outrage, with Democrats and Republicans accusing each other of spreading hateful rhetoric, and a hunt for his killer. Utah's Governor Spencer Cox said Robinson had been arrested after confessing about Kirk's killing to his father and being persuaded to hand himself in.
Law enforcement sources have told CBS News that Robinson and his friends bantered about the shooting before his arrest in a group chat on Discord involving more than 20 people.
The spokesperson for the platform said that an internal investigation by the company had found no evidence that the suspect planned this incident or promoted violence on Discord.
Investigators have been trying to establish a motive for the killing, with discussions about Robinson's political affiliations and reported comments on Kirk's visit to the university surfacing amidst the investigation.
The aftermath of the shooting has not only raised legal questions but has also incited fierce public discourse surrounding political rhetoric and the responsibilities of social media platforms.
