Police are looking for a person believed to have purchased the handguns used by two people involved in the shooting death of U.S. Border Patrol agent David "Chris" Maland earlier this month in northern Vermont.

A Washington state woman has been ordered to be held without bail in connection with the death of a U.S. Border Patrol agent in Vermont.

Michelle Zajko, 32, supplied the gun that killed US Border Patrol agent David Maland last week -- and may be tied to two other homicides in California and Pennsylvania, federal authorities said.

The recent murder of an 82-year-old Vallejo man may be connected to the murder of a border patrol agent in Vermont and a double homicide in Pennsylvania.

At a hearing and in court filings, a federal prosecutor in Vermont cited connections between the defendant, Teresa Youngblut, and people linked to other murder investigations.

Prosecutors say the Washington state woman charged in the killing of a Border Patrol agent in Vermont was in contact with homicide suspect.

Teresa Youngblut was ordered held without bail in connection with the death of U.S. Border Patrol agent David Maland in a case that has grown to encompass killings in multiple states.

Police records show that law enforcement officials are searching for a 32-year-old woman related to the purchase of the firearms allegedly used in the killing of Border Patrol agent David Maland.

Prosecutors are arguing why a Washington state woman should remain jailed in connection with the death of a U.S. Border Patrol agent

The judge agreed Thursday to the prosecution’s request that Teresa Youngblut be detained while her case proceeds because the evidence appeared “to be strong.”
