The two people involved in the fatal shooting of Vermont U.S. Border Patrol Agent David “Chris” Maland have been identified. Teresa Youngblut, 21, of Washington state, has been charged with assault on a federal law enforcement officer and is also facing a firearms charge.

A woman has been arrested in connection with the fatal shooting of US Border Patrol agent earlier this week on a highway in Vermont close to the US-Canadian border, the FBI office in Albany said Friday.

Agent David “Chris” Maland died in a shooting following a traffic stop, the FBI said. A second person killed in the incident was a German national in the country on a current visa, authorities said.
