A Washington state woman has been charged in the fatal shooting of a U.S. Border Patrol agent in Vermont, which happened days after authorities began watching her and a German companion who also died in the roadside shootout, the FBI said Friday.

The US Border Patrol agent murdered during a traffic stop with a migrant in Vermont was an Air Force veteran who survived the 9/11 attack on the Pentagon, his family said. David “Chris” Maland, 44, died Monday afternoon after a shootout with a German national on Interstate 91 about 20 miles from the Canadian border,
