ICE Buffalo investigation leads to arrest of Jamestown man charged with threatening to kill a Homeland Security agent

BUFFALO, N.Y. — An investigation by ICE Homeland Security Investigations Buffalo has resulted in the July 1 arrest of 43-year-old Matthew White. White, of Jamestown, New York, was charged by criminal complaint with communicating interstate threats for allegedly making social media posts threatening to kill ICE personnel. In one post, he allegedly threatened to target an individual’s children.

ICE HSI Buffalo Special Agent in Charge Erin Keegan and U.S. Attorney U.S. Attorney Michael DiGiacomo, of the Western District of New York, announced the charges.

“The defendant stands accused of making vile threats against officers and agents who risk their lives every day to uphold an oath they swore to protect the public — even those who wish them harm. There is no place in our community for such hate against any human beings, including and especially innocent children,” said Keegan. “Let it be known, HSI Buffalo is unflinchingly committed to finding and investigating any individuals who threaten, or who are intent on hurting, members of our law enforcement community.”

According to the investigation and outlined in the complaint:

On April 30, HSI Buffalo personnel learned that an X account, believed to be operated by White, was engaged in publicly posting threats to federal immigration agents and administrators employed by the Department of Homeland Security.

On June 4, White voluntarily spoke with investigators and allowed them to extract and copy the contents of his phone. Investigators recovered a number of threatening posts on X, including:

• On April 18, White posted, “Kill them all, ICE is the new age gestapo, stop them.”
• On April 29, White shared a video clip of Border Czar Tom Homan posted by an X user “America,” and commented, “Then understand that if your ICE agents don’t show proof of identity and a signed warrant, we will kill them.”
• In late April, White posted multiple threatening and violent public comments in response to coverage of several ICE arrest operations, including an ICE arrest operation inside a Virginia courthouse that occurred in April 2025. White posted, “I can’t wait to put a bullet into this guy’s brain, but first his children.”

White made an initial appearance on the afternoon of July 1 before U.S. Magistrate Judge Jeremiah J. McCarthy and was released on conditions.

The fact that a defendant has been charged with a crime is merely an accusation and the defendant is presumed innocent until and unless proven guilty.
