On the afternoon of January 20, 2025, a traffic stop on Interstate 91 near Newport, Vermont, turned deadly when United States Border Patrol Agent David Christopher Maland, 44, was shot and killed. A veteran of the U.S. Air Force and a K-9 handler assigned to the Swanton Sector, Maland had served with the Border Patrol for nearly a decade and previously worked as a Pentagon security officer during the September 11th attacks.

A shootout followed; the male suspect, identified as Felix Baukholt, was killed at the scene. The female suspect, Teresa Youngblut, 21, was wounded and taken into custody and has been federally charged in connection with Maland’s death. Investigators have suggested a possible link between the suspects and a group referred to as the Zizians, which is reportedly of interest to federal prosecutors in other violent incidents.

Maland’s family and colleagues remembered him for his dedication and service; he was planning to marry his partner. Does anyone have information about movements of the vehicle on Interstate 91 that afternoon or about the group called the Zizians?
