On Thursday, a grand jury indicted Teresa Youngblut on two counts of using a deadly weapon and discharging that weapon while resisting a federal agent.

The weapon that killed Agent David Maland last week in northern Vermont was bought by a person of interest in a double murder two years ago in Delaware County, state police say.

The FBI has acknowledged connections with other deaths but has not yet publicly discussed the broader investigation.

The woman charged in connection to the killing of a United States Border Patrol Agent in northern Vermont has now been indicted by a federal grand jury.
