The man accused of last week’s attack on two United States National Guard (USNG) members made his first court appearance on Tuesday — pleading not guilty via video connection from a hospital bed, where he remains under guard after being wounded.

The suspect, Rahmanullah Lakanwal, faces charges including first-degree murder and assault with intent to kill after one Guardsman was killed and another critically injured in a downtown Washington, D.C., ambush.

Authorities allege Lakanwal drove from Washington State to the U.S. capital, studied the guardsmen near the Farragut West Metro Station, then opened fire with a .357-caliber revolver while shouting “Allahu Akbar.” The attack struck 20-year-old Specialist Sarah Beckstrom and 24-year-old Staff Sergeant Andrew Wolfe.

Beckstrom later died; Wolfe remains hospitalised in critical condition.

Court documents describe the shooting as a deliberate and premeditated attack.

A National Guard supervisor and other troops returned fire, wounding Lakanwal before a bystander subdued him as he tried to reload.

No evidence of additional accomplices has emerged.

At the hearing, which lasted roughly half an hour, Lakanwal — visibly impaired, reportedly unable to open his eyes and in pain — had his plea entered by a court-appointed attorney.

Magistrate Judge Renee Raymond ordered him detained without bond, citing the strength of the government’s case, including surveillance recordings showing him waiting in ambush for the guardsmen.

The U.S. Attorney for the District of Columbia said more charges are possible.

Prosecutors are also examining whether to seek capital punishment, given the violent targeting of federal troops.

The case has drawn national attention.

The attack occurred under the deployment of roughly 2,200 National Guard troops to Washington under orders from US President Donald J. Trump as part of a broader crackdown on crime.

The shooting has intensified debate over immigration and asylum policy: Lakanwal is an Afghan national who entered the United States in 2021 under a humanitarian parole programme and was granted asylum earlier this year.

Law-enforcement sources said they are exploring whether radicalisation, mental-health issues, or a possible ideological motive explain the attack; however, no definitive evidence connecting Lakanwal to any foreign extremist organisation has yet emerged.

Investigators have seized multiple electronic devices from the suspect’s residence and interviewed family members as part of a nationwide probe into potential ties or conspiracy networks.

His next court hearing is scheduled for mid-January 2026.

As the investigation proceeds, security remains heightened in the capital.

Additional National Guard deployments and joint patrols with local police have been ordered, and immigration officials have paused processing of asylum applications for certain nationalities while reviewing recent admissions.
