Federal prosecutors have revealed a connection between the woman charged in the death of a U.S. Border Patrol agent and a suspect in two murder investigations. Teresa Youngblut, 21, is facing weapons charges related to the fatal shooting of Agent David Maland during a traffic stop in Coventry, Vermont, on January 20th. She was traveling with German citizen Felix Bauckholt, who was also killed in the incident.
The firearms used by Youngblut and Bauckholt have been linked to a third individual in Vermont who purchased them. This individual, according to prosecutors, is a person of interest in an ongoing double homicide investigation in Pennsylvania and a separate murder investigation in Vallejo, California. Further details about these investigations have not been released.

Agent Maland, a Minnesota native and Air Force veteran, served at the U.S. Customs and Border Protection’s Newport Station. He dedicated nine years to the military and 15 years to federal service.
Prosecutors have requested Youngblut be held in custody, citing her as a danger to the community and a flight risk. They highlighted her possession and use of a firearm, coupled with her travel plans and associations, as evidence of this risk.
Authorities previously reported that Youngblut and Bauckholt were in possession of an array of weapons and tactical gear, including ammunition, a ballistic helmet, and night vision equipment.

The fatal shooting occurred during an immigration inspection. While initially believed to have an expired visa, Bauckholt's visa was later confirmed as valid. Court documents indicate that Youngblut opened fire on agents during the traffic stop, leading to return fire.

Youngblut recently appeared in court in Burlington, Vermont. The investigation remains ongoing.
