A Los Angeles man received a 37-month federal prison term after admitting he joined a crowd that hurled burning debris and stones onto a freeway overpass, endangering California Highway Patrol officers trapped beneath a downtown bridge.
The case centers on violence that erupted on June 8, 2025, two days after confrontations with federal agents enforcing immigration laws. Authorities say a large group gathered on the Main Street overpass above U.S. Highway 101 and began picking up cardboard, vegetation and fireworks, setting them alight and sending them over the railing. One CHP vehicle was set on fire and officers were trapped beneath the overpass while the burning material and rocks rained down. The incident prompted a federal investigation led by the FBI with assistance from local law enforcement agencies.
Ismael Vega, 42, later admitted his active role and pleaded guilty on April 29 to a single count of obstructing, impeding, and interfering with law enforcement during a civil disorder. On Monday, United States District Judge John F. Walter handed down a 37-month sentence and ordered Vega to pay $253,415 in restitution. Court filings describe repeated, deliberate actions by Vega and other members of the crowd designed to target the officers and the CHP vehicle near them. Prosecutors tied his conduct directly to the substantial risk of death or serious bodily injury that the burning debris and thrown objects created.
According to the plea agreement, Vega lit a large piece of cardboard, held it over the railing and timed its drop so it landed on the hood of the CHP vehicle below. After the cardboard ignited the vehicle, another individual poured a liquid that intensified the flames, and Vega stood close enough to gesture and motion toward the growing fire. He also picked up and threw multiple rocks at law enforcement officers who were trying to clear the overpass, actions he later admitted were intended to obstruct and impede their duties. The record shows multiple efforts to assist others lighting debris that night, rather than any attempt to de-escalate the scene.
Federal authorities described the event as more than a chaotic protest, calling it a significant episode of civil disorder. “This civil disorder stood apart in its magnitude,” prosecutors wrote in a sentencing memorandum, noting a statement from a CHP sergeant with nearly three decades on the force about the lasting impact on him and his family. That testimony underscored the real human toll on officers who faced sustained and coordinated attacks while performing their duties. The written accounts and body-worn camera evidence in the file framed the sentencing recommendation and restitution calculation.
Vega is the fifth defendant to be sentenced in connection with the broader case stemming from the violence on the overpass. One co-defendant, Yachua Mauricio Flores, 23, faces a statutory maximum of five years and is scheduled for an August 3 sentencing hearing. The lead defendant, Adam Charles Palermo, 40, faces a separate sentencing date on December 14 and could confront a statutory maximum of 20 years in federal prison. Prosecutors say the group’s actions and the coordination among participants drove the federal response and the decision to bring charges under statutes addressing civil disorder and obstruction of law enforcement.
The investigation combined resources from federal and local law enforcement and produced a prosecution overseen by a team from the U.S. Attorney’s Office. Assistant United States Attorneys Jenna W. Long and Lana Morton Owens from the National Security Division, along with Assistant United States Attorney Sebastian Bellm of the General Crimes Section, handled the case. Their filings and presentations to the court emphasized both the objective danger created by the crowd and the defendants’ conscious decisions to participate. Sentences and restitution amounts reflect both the seriousness of the conduct and the court’s view of accountability for those actions.
Details submitted at sentencing describe how the crowd used readily available items as weapons, turning cardboard and vegetation into burning projectiles and combining them with fireworks. Those actions created multiple hazards for officers positioned under the overpass and for motorists on the freeway below. The record also documents attempts by people in the crowd to amplify the flames and to obstruct law enforcement movements as officers tried to secure the scene. Federal prosecutors highlighted those coordinated steps when arguing for significant penalties.
Court documents and statements from law enforcement officials characterize the night as a particularly violent episode that left an outsized impression on those who responded. Victim impact statements and sworn accounts were part of the sentencing materials that the judge reviewed before imposing prison time and restitution. The case remains active for other defendants, and additional hearings are scheduled as the prosecution continues to pursue charges tied to the same June 2025 events.
