Jeffrey Adam Crum has been sentenced to 12 months and one day in federal prison for assaulting a Deputy U.S. Marshal. The sentence, handed down by Senior U.S. District Judge Susan Illston, also includes a concurrent term of the same length for violating the terms of his supervised release.
Crum, 34, who previously lived in Burlingame and San Francisco, was indicted by a federal grand jury on December 3, 2024. He pleaded guilty on May 16, 2025, to one count of assaulting, resisting, or impeding a federal officer in violation of 18 U.S.C. § 111(a)(1). According to court documents and the plea agreement, Crum appeared in federal court on November 22, 2024, for a hearing regarding allegations that he violated the terms of his supervised release following his conviction for being a felon in possession of a firearm and ammunition in federal court in Utah.
During the hearing on Crum’s supervised release violation, the district court ordered that Crum be detained pending further proceedings. Crum opposed this decision and resisted efforts by multiple Deputy U.S. Marshals to take him into custody. Specifically, he resisted instructions by Deputy U.S. Marshals to enter and exit an elevator leading to a holding cell, forcing them to carry him. At one point during this incident, Crum kicked his legs out and struck a Deputy U.S. Marshal in the head.
United States Attorney Craig H. Missakian and Supervisory Deputy United States Marshal David Siegel announced the sentencing.
The defendant was immediately remanded into custody following the sentencing.
Special Assistant U.S. Attorneys Eli J. Cohen and Christine Chen prosecuted the case with assistance from Marina Ponomarchuk and Kevin Costello. The prosecution resulted from an investigation conducted by the U.S. Marshals Service.
