During a news conference yesterday, Utah County Attorney Jeff Gray said Tyler Robinson – who is accused of murdering Charlie Kirk – was in a “romantic relationship” with his roommate, a “biological male… undergoing a gender transition”.

Over the weekend, the Daily Mail said it had found, external a number of social media accounts allegedly linked to the roommate. It mentioned a specific username. We used this to search online and found accounts in this name on Steam, a platform popular with online gamers, Discord, Reddit, Instagram, Facebook, Threads and TikTok.

While most of the posts from those accounts were related to gaming and online culture, the user did engage in some politics-related discussion on Reddit, including comments on forums dedicated to transgender people, religion and capitalism. In one comment, the user spoke about their personal experience of transitioning, describing how they had been told they were “possessed by a demon” and “kicked out of the house”.

Using the friends lists associated with those accounts, some online sleuths claim to have found Tyler Robinson’s profiles on platforms like Steam, Reddit and Venmo, a mobile payment app.

Comments posted by the accounts allegedly owned by Robinson were mostly linked to gaming.

BBC Verify has reviewed all of the accounts, but is unable to confirm that they belong to Robinson and his roommate.

The BBC has contacted Reddit, Discord and Steam for comment on the ownership of the profiles.
