Teresa Youngblut, 21, faces two weapons charges in connection with the death of Border Patrol Agent David Maland, 44, who died Jan. 20 during the shootout in Coventry.

Prosecutors say a Washington state woman charged in connection with the fatal shooting of a U.S. border patrol agent had been in frequent contact with someone whom authorities have linked to homicides in Pennsylvania.

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.

The woman accused of killing U.S. Border Agent David Maland allegedly used a gun bought by someone who was a person of interest in a double murder, prosecutors said.

Teresa Youngblut, the woman charged in the shooting death of U.S. Border Patrol Agent David "Chris" Maland, has a detention hearing on Jan. 30.

Federal prosecutors have filed a motion seeking to keep Teresa Youngblut in custody in Vermonth while she awaits trial on charges connected to the shooting death of a Border Patrol agent. WPTZ's Jackson Stoever reports.
