BBC Verify is working to find about more about the man suspected of yesterday’s shooting at a US Immigration and Customs Enforcement (ICE) facility in Dallas, Texas, in which one detainee was killed and two others were wounded.

The suspect, Joshua Jahn, 29, was named by acting ICE director Todd Lyons, according to the BBC’s US news partner CBS – confirming a name posted earlier on social media by a New York Post/Fox News columnist.

Our team has been reviewing Jahn’s digital footprint including social media profiles that are linked to him or his relatives.

Using SkopeNow, an open-source intelligence platform that finds and aggregates public data, we found Texas criminal records for a Joshua Jahn on a 2016 drug-related charge, as well as two other unspecified charges from 2016 and 2022, both of which were dismissed.

Many of his social profiles are now deleted and most have no archived copies. A LinkedIn profile lists him as a former University of Texas mechanical engineering student. He also had an old account for a site about chess which has been inactive since 2015.

We also looked into a claim by right-wing commentator and Trump ally Laura Loomer that Jahn’s Facebook page featured antifa (anti-fascist) imagery. Her assertion centres on a cartoon image of a man with a gun which features communist memorabilia and is captioned “Glorious exposition, comrade”.

We haven’t seen any evidence linking this image to antifa. The cartoon aligns with a common “cool story, bro” meme used sarcastically online. It is also not possible to verify whether the image appeared on his Facebook page as we have not found an archived version of it.

Screenshots circulating online appear to show his mother’s Facebook page – which has now been deleted – featured a post criticising gun laws and Texas Republicans.

So far we’ve not found anything online that gives an indication of Jahn’s political views. We’re continuing to search for information available online that can help us build a picture of who Jahn was.
