The U.S. Secret Service arrested Mathre on Feb. 6. A federal grand jury has since returned an indictment charging Mathre with making the threat against Vance.
While investigating the threats, federal agents found "multiple digital files of child sexual abuse materials (CSAM)" in Mathre's possession, according to prosecutors. Subsequently, the grand jury also charged that "from about Dec. 31, 2025, to Jan. 21, 2026," Mathre engaged in the receipt and distribution of CSAM.

ATTORNEY FOR SUSPECT IN VANCE HOME VANDALISM RULES OUT POSSIBLE MOTIVATION
Vance faced multiple death threats and had his Ohio home vandalized last month.
William DeFoor, 26, was arrested in early January in connection with the vandalism of Vance's home. DeFoor was booked on charges of vandalism, obstruction of official business, criminal damaging or endangering, and criminal trespass.
"I appreciate everyone's well wishes about the attack at our home. As far as I can tell, a crazy person tried to break in by hammering the windows. I'm grateful to the secret service and the Cincinnati police for responding quickly. We weren't even home as we had returned already to D.C.," Vance wrote on X.
In another January incident, Marco Antonio Aguayo, 22, of Anaheim, was also arrested after allegedly making multiple threatening comments on Disney’s official Instagram account referencing pipe bombs, imminent bloodshed and violent action against "corrupt politicians" on July 12, the same day Vance and his family were visiting and staying at the resort.

Additionally, Fox News Digital reported exclusively that a volunteer radio show host resigned after authorities confirmed they are aware of a post threatening Vance on left-wing-dominated social media app Bluesky. The person identified themselves as a host of a radio show on WUML, which is funded by the University of Massachusetts at Lowell.
The university told Fox News Digital that it alerted authorities once it became aware of the post. Secret Service confirmed to Fox News Digital that it was aware of the post. The Haverhill Police Department directed Fox News Digital to the FBI, which declined to comment.
