Accused WH correspondents’ dinner attacker is tutor and computer programmer from California

The writings ran more than a thousand words and read as a rambling, deeply personal message, opening almost jarringly with a casual “hello everybody!” before shifting into apologies to family members, co-workers, fellow travelers and even strangers he feared could be caught in the violence. The note moved between confession, grievance and farewell, with Allen thanking people in his life even as he sought to explain the attack.

Elsewhere, the document veered between political anger, religious justifications and rebuttals to imagined critics, at times reading as if he were arguing with detractors in real time.

Authorities said Allen will face charges including using a firearm during a crime of violence and assault on a federal officer, as well as other potential counts. A search of state and federal court databases showed no indication Allen had ever previously been charged with a crime.

He signed the document using a moniker that matches social media accounts that have since been taken offline. A defunct account using the same name on the platform Bluesky reposted others who offered commentary critical of Trump as well as members of the media who attend the annual black-tie dinner.

The AP limits the use of attackers’ writings and social media posts to avoid amplifying their views or encouraging copycat actions. The AP chooses to summarize their words and focus mainly on the victims and investigations.

Allen was arrested Saturday night trying to rush past a security checkpoint with two firearms and knives. Law enforcement officials told the AP that Allen legally bought a .38-caliber semiautomatic pistol in October 2023 and a 12-gauge shotgun last year.

Canvassing the suspect’s neighborhood

Voter registration records from California lists Allen’s home address as his parent’s house on a tree-lined street in one of the most historic neighborhoods in Torrance, a city within the Los Angeles metro area. Public records show he is the oldest of four adult siblings, with two younger sisters and a brother.

Two cars were parked in the driveway Sunday morning. A blue scooter that a neighbor said Allen rode was on the front lawn. No one answered the door when an Associated Press reporter knocked. By the afternoon, several people who appeared to be law enforcement agents were canvassing the neighborhood, with one wearing an FBI sweatshirt.

A yard sign displayed at the family home supported a local candidate for judge who was endorsed by the Los Angeles County Democratic Party. Federal campaign finance records show Cole Allen contributed $25 to a Democratic Party political action committee in support of Kamala Harris for president in 2024 and listed his employer as C2 Education.

A 2024 post on the C2’s Facebook page listed Allen as the company’s teacher of the month. The company did not immediately respond to an email seeking comment Saturday night and an office in Torrance was closed on Sunday.

Allen’s profile photo on LinkedIn shows him wearing a cap and gown when graduating with a master’s degree in computer science from California State University, Dominguez Hills. The photo appears to have been taken May 2025. Bin Tang, a computer science professor at the school, told the AP that Allen took a few of his classes.

“He was a very good student indeed, always sitting in the first row of my class, paying attention, and frequently emailing me with coursework questions. Soft-spoken, very polite, a good fellow. I am very shocked to see the news,” Tang wrote in an email.

He earned a bachelor’s degree in 2017 in mechanical engineering from the California Institute of Technology in Pasadena, according to his profile on the social networking site LinkedIn. The small university is academically prestigious with a very low acceptance rate. He also listed his involvement there in a campus group that battled with Nerf guns and a Christian student fellowship.

The suspect’s father, Thomas Allen, is listed as an elder at Grace United Reformed Church Torrance. The webpage for the congregation describes it as a “Bible-believing church” following the “infallible Word of God.” Security guards posted at the sanctuary during worship services on Sunday escorted parishioners to the door and kept reporters at bay.

Allen also posted that he had developed a video game for the Steam platform based on molecular chemistry. A post under Allen’s name said he was working to develop a new “top-down shooter” combat game set in outer space.
