The Vermont Border Patrol agent murdered when he stopped a migrant near the northern border has been identified as David C. Maland, The Post has learned.

An agency veteran of nearly a decade, Maland, 44, had been assigned to the Newport, Vermont, Border Patrol station when he was gunned down on Interstate 91 near Coventry at about 3:15 p.m. on Monday, according to federal law enforcement sources.

“A Border Patrol agent assigned to the US Border Patrol’s Swanton Sector was fatally shot in the line of duty,” acting DHS Secretary Benjamine Huffman said in a statement, according to Fox News.

“Every single day, our Border Patrol agents put themselves in harm’s way so that Americans and our homeland are safe and secure.”

One of Maland’s attackers was killed and a second was injured. The wounded man is in federal custody, sources said.

Maland had been working in the Border Patrol’s Swanton sector, which encompasses Vermont and parts of New York and New Hampshire.

The FBI has said there is no further threat to the public.

The agent was killed on the same day that Donald Trump was sworn into the presidency after a campaign in which he claimed he’d crack down on illegal immigration and step up border security.

Vermont’s two liberal senators — Bernie Sanders and Peter Welch — and Democratic Congresswoman Becca Balint sent the agent’s family their condolences and said border patrol agents “deserve our full support in terms of staffing, pay and working conditions,” according to Border Report.

House Committee on Homeland Security Chairman Mark E. Green said Tuesday he was “heartbroken” by the killing.

“We owe an immense debt of gratitude to Agent Maland for nearly a decade of service protecting our communities in the force,” the Tennessee Republican said.

“We must never forget that the men and women in green on the frontlines of this border crisis defend our homeland at great personal cost,” he added. “Far too often these courageous public servants, like Agent Maland, pay the ultimate price.”
