Jeffrey Caldwell, 37, of Vallejo, was sentenced today by U.S. District Judge Dena Coggins to 14 years and seven months in prison for being a felon in possession of ammunition, U.S. Attorney Eric Grant announced.
On May 13, 2025, following a two-day trial before Judge Coggins, a jury found Caldwell guilty of being a felon in possession of ammunition. Caldwell is prohibited from possessing firearms or ammunition due to his 14 prior felony convictions, which include convictions for assault, burglary, and stalking.
According to court documents and evidence presented at trial, on Dec. 16, 2024, when multiple guests of a motel in Vallejo called 911 to report that Caldwell was firing a gun inside the building. Officers from the Vallejo Police Department (VPD) quickly responded and evacuated the building, at which point Caldwell barricaded himself in his room and refused to surrender. The Vallejo Police deployed their SWAT and Hostage Negotiation Teams, beginning a multi-hour standoff which lasted into the early morning of the next day.
The standoff finally ended when the SWAT Team deployed chemical agents into Caldwell’s room, which forced him out. Caldwell attempted to flee but was quickly arrested. A search of Caldwell’s person did not locate the firearm, but when the officers entered his room, they found a large hole in the bathroom wall. Stuffed inside the hole were multiple items, including a shower curtain, clothing, a canister of bear spray, and a pistol. Officers inspected the gun and determined that it was a privately manufactured firearm, commonly referred to as a ghost gun due to its lack of a traceable serial number. Caldwell had left the gun with a single round of ammunition still in the chamber.
This case was the product of an investigation by the Federal Bureau of Investigation, the Vallejo Police Department, and the Bureau of Alcohol, Tobacco, Firearms and Explosives. Assistant U.S. Attorneys Charles Campbell and R. Alexander Cárdenas prosecuted the case.
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.
