Afghan immigrant who allegedly killed National Guard member near White House and critically injured another showed warning signs for over a year, emails reveal mental health crisis went unaddressed.

An Afghan suspected terrorist “disappeared” roughly two weeks before he allegedly ambushed and shot two National Guard soldiers in Washington, DC, one of his neighbors revealed. Rahmanullah Lakanwal, 29, lived a quiet life in Bellingham, Washington, but struggled to find work, neighbor Mohammad Sherzard told the Associated Press.

The Trump administration is promising a stricter anti-immigration agenda after an Afghan national was being charged in the shooting of two National Guard members.

More than 40% of those brought to the U.S. under Operation Allies Welcome were eligible Special Immigrant Visas because they worked with the U.S. in some way over the prior two decades, or were related to someone who did. Others were allowed to resettle in the U.S. for humanitarian reasons, according to the Department of Homeland Security.
