The federal sentencing of former San Diego County Sheriff’s Deputy Aaron Russell concluded this week with a 12-year prison term after a jury found he unlawfully shot an unarmed man who was fleeing custody. The case centers on the May 1, 2026 encounter in which 36-year-old Nicholas Bils was struck by multiple rounds while running from a transport vehicle near the San Diego Central Jail.

The conviction was the result of a retrial in federal court following an earlier deadlock. Jurors concluded that Russell’s actions violated Bils’ civil rights and that he used a firearm in connection with a violent crime. The case has also produced state-level pleas, a civil settlement and lasting debate about law enforcement use of force.

What the jury found and the sentence imposed

In March, a federal jury convicted Russell of deprivation of rights under color of law and of using and discharging a firearm during a crime of violence. U.S. District Judge Todd Robinson imposed a consecutive sentence: two years for the civil rights violation followed by the mandatory minimum 10-year term for the firearm offense, for a total of 12 years.

Prosecutors had urged a 13-year term, arguing the shooting was not a split-second mistake but a willful abuse of power that undermined public trust in policing. Defense lawyers asked for a lighter sentence, framing the shooting as a tragic, split-second choice by a young officer with limited experience.

Events leading up to the shooting

The incident occurred on May 1, 2026, when Bils was being transported after an arrest at Old Town San Diego State Historic Park. According to court evidence, Bils slipped out of his handcuffs and ran while still partially restrained. Russell, then 23 and about a year out of the training academy, drew his weapon and fired multiple shots at Bils as he fled.

Four rounds struck Bils in the back, arm and thigh; one round penetrated the chest area, causing fatal injuries. Other officers present testified they did not draw their weapons or believe lethal force was required. At trial, Russell said he thought Bils held a gun, a claim prosecutors challenged, noting that what Russell later acknowledged seeing was a dangling handcuff.

State prosecution and civil settlement

Following the shooting, Russell resigned from the Sheriff’s Department and faced state charges, including second-degree murder. He ultimately pleaded guilty in 2026 to voluntary manslaughter, receiving a one-year jail term and probation. Separately, San Diego County settled a wrongful death lawsuit with Bils’ family for $8.1 million in mid-2026.

Arguments at sentencing and reactions

At the federal sentencing hearing, prosecutors portrayed Russell’s testimony as dishonest and emphasized the broader consequences of the killing. Assistant U.S. Attorney C. Seth Askins argued the defendant’s initial statements omitted any mention of seeing a gun and that the shooting endangered bystanders, including a woman whose car was struck by a bullet and a pursuing officer who was nearly in the line of fire.

Defense attorney Jeremy Warren urged leniency, describing the case as an isolated lapse by a once-promising officer who is now a father and has supporters in the courtroom. The defense highlighted Russell’s youth and lack of prior misconduct as reasons the judge could impose a lighter term. Warren also signaled an appeal of a pre-sentencing ruling upholding the firearm conviction.

Family statements and community impact

Statements read at sentencing illustrated the split within the victim’s family and community. Bils’ mother expressed profound pain and condemned the idea that someone sworn to protect could kill a person for fleeing. Other relatives echoed anger, fear of law enforcement and the long-term trauma the family has endured.

Prosecutors framed the sentence as necessary to restore public confidence and to convey that law enforcement officers are held to a higher standard. Judge Robinson similarly noted the gravity of an officer taking a life and explained that expectations for accountability are heightened because of the power and trust inherent in policing roles.

Aftermath and next steps

Russell has been permitted to remain free on bond for now but was ordered to report to prison by a court-set date. The defense plans to challenge the firearm conviction on appeal, raising legal questions that could be reviewed by the Ninth Circuit. Meanwhile, the case remains a focal point in San Diego discussions about use-of-force policies and training.

Beyond the legal proceedings, the incident has had wider ripple effects: a substantial civil settlement, a rare on-duty murder charge in the county, and renewed scrutiny of how agencies handle detainees, perceived threats and split-second encounters. The sentence closes one chapter in a long and painful story for the Bils family, while potential appeals and policy conversations may continue to shape its legacy.
