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.

The killings of a Border Patrol agent in Vermont last week, a state’s witness in California, and a pair of senior citizens in Pennsylvania all appear to be linked to a fringe group of West Coast vegan activists and artificial intelligence theorists.

A double murder of Richard and Rita Zajko in December 2022 has been linked to the fatal shooting of a Border Patrol Agent in Vermont.

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.

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.

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.

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

The gun used in the shooting death of a Delaware County couple was used in connection with the line-of-duty shooting death of a border patrol agent in Vermont, officials said.

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.

The U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives sent an alert to federally licensed firearms dealers a day after the shooting seeking information related to any gun purchases by Michelle Jacqueline Zajko.

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 in Vermont and across the region 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.
