Vallejo Man Pleads Guilty to Assaulting Federal Agents with a Firearm and Vehicle

SACRAMENTO, Calif. - Sean Thomas Delapp, 37, of Vallejo, pleaded guilty today to assaulting federal officers with a deadly weapon, U.S. Attorney Phillip A. Talbert announced.

According to court documents, Delapp assaulted two FBI special agents by pursuing them with his car, pulling up alongside them, and aiming a firearm at them through the window, making a recoil motion with the firearm. A subsequent search warrant at his residence resulted in the discovery of a Glock 29 firearm, ammunition, and various firearm parts. Delapp is prohibited from possessing firearms or ammunition because he was previously convicted of a felony evasion offense.

This case was the product of an investigation by the Federal Bureau of Investigation, the California Highway Patrol, and the Bureau of Alcohol, Tobacco, Firearms and Explosives. Assistant United States Attorney Adrian T. Kinsella is prosecuting the case.

Delapp is scheduled to be sentenced on October 31, 2024. He faces a maximum statutory penalty of 20 years in prison and a $250,000 fine. Any sentence, however, would be determined at the discretion of the court after consideration of any applicable statutory factors and the Federal Sentencing Guidelines, which take into account a number of variables.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the U.S. Department of Justice launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.
