This verified explainer outlines the four former Minneapolis law enforcement officers involved in George Floyd’s death on May 25, 2020, and the outcomes of their criminal trials. Derek Chauvin was convicted of second-degree unintentional murder, third-degree murder, and second-degree manslaughter; Tou Thao, J. Alexander Kueng, and Thomas Lane were convicted of aiding and abetting second-degree murder and aiding and abetting second-degree manslaughter. The case prompted nationwide legal reforms, clarified standards of police duty and bystander intervention, and established precedent for convicting officers in custodial deaths. Below is a detailed profile of each officer, their charges, trial results, and sentences.
Derek Chauvin: lead officer and primary defendant
Role on May 25, 2020
Derek Chauvin, a Minneapolis Police Department officer for nearly 20 years, pressed his knee into George Floyd’s neck for approximately 9 minutes and 29 seconds while Floyd was handcuffed and lying face down on the street. The prosecution argued this use of force was unreasonable and a substantial factor in Floyd’s death; the defense initially claimed Floyd’s drug use and underlying health conditions were primary factors. On April 20, 2021, a Hennepin County jury found Chauvin guilty on all three counts: second-degree unintentional murder, third-degree murder, and second-degree manslaughter. On June 25, 2021, he was sentenced to 22.5 years in state prison; a separate federal sentence added 21 years, to run concurrently, for violating Floyd’s civil rights through excessive force and ignoring serious medical needs. Chauvin’s convictions marked a rare instance of a Minnesota officer convicted of murder in the line of duty.

Tou Thao: bystander intervention and federal outcomes
Role and actions
Tou Thao, a Minneapolis police officer since 2008, stood between the officers and bystanders who attempted to intervene while Floyd was restrained. Prosecutors argued his failure to provide medical aid or remove officers from the scene constituted aiding and absecond-degree murder and second-degree manslaughter. In May 2022, a Hennepin County jury convicted Thao on both state counts. He was sentenced in July 2022 to 3.5 years in prison for state offenses; he also pleaded guilty in federal court in 2023 to a civil rights violation and received a concurrent 3-year sentence. Thao’s case underscored the legal significance of failing to act when safe and feasible.

J. Alexander Kueng: medical aid and federal responsibility
Role and actions
J. Alexander Kueng, a Minneapolis police officer with about two years of service, responded to the scene and helped restrain Floyd after being ordered by senior officers. He was charged with aiding and abetting second-degree murder and second-degree manslaughter. In November 2022, a jury convicted Kueng on both counts. He was sentenced in January 2023 to 4 years in state prison. Kueng also pleaded guilty federally in 2023 to failing to intervene and to misusing property under color of law, receiving a 3.5-year sentence to run concurrently with his state time. Kueng’s case highlighted the duty to intervene and the legal consequences of assisting in excessive force.

Thomas Lane: duties, medical aid, and federal resolution
Role and actions
Thomas Lane, a Minneapolis police officer with approximately 7 years of service, helped restrain Floyd by holding his legs. He was charged with aiding and abetting second-degree murder and second-degree manslaughter. In May 2022, a jury convicted Lane on both charges. He was sentenced in June 2022 to 3 years in state prison. Like his co-defendants, Lane entered a federal guilty plea in 2023 to failing to intervene and to misusing property under color of law, resulting in a 3-year concurrent federal sentence. Lane’s case reinforced that even officers without direct use-of-force responsibility can be held liable for omissions when safety requires action.

Comparative summary of charges and sentences
The four officers faced parallel state and federal pathways. State sentences reflected the gravity of their roles and the public’s interest in accountability, while federal sentences addressed civil rights violations. All four admitted legal responsibility at either the state or federal level, illustrating the breadth of culpability across the conduct chain—from the officer who applied the fatal restraint to those who failed to intervene or provide aid.
| Officer | State charges | State sentence | Federal charges (as entered) | Federal sentence |
|---|---|---|---|---|
| Derek Chauvin | 2nd-degree murder, 3rd-degree murder, 2nd-degree manslaughter | 22.5 years | Civil rights violations (killing and medical neglect) | 21 years concurrent |
| Tou Thao | Aiding & abetting 2nd-degree murder, aiding & abetting 2nd-degree manslaughter | 3.5 years | Failure to intervene, misuse of property | 3 years concurrent |
| J. Alexander Kueng | Same as Thao | 4 years | Failure to intervene, misuse of property | 3.5 years concurrent |
| Thomas Lane | Same as Thao | 3 years | Failure to intervene, misuse of property | 3 years concurrent |
Broader legal and policy implications
The Floyd case clarified that prosecutors can pursue higher-level offenses when use of force results in death, and it expanded understanding of when officers must intervene to protect citizens. It prompted state-level duty-to-intervene statutes, stricter use-of-force policies, and increased scrutiny of qualified immunity in civil actions. These outcomes continue to shape training, supervision, and accountability measures nationwide, serving as a durable reference point for future reform and litigation.
Definitions and context
- Aiding and abetting: Providing assistance, encouragement, or omission of required action that facilitates a crime; in these cases, failing to prevent or mitigate excessive force.
- Second-degree murder: Intentional act causing death without premeditation; in Minnesota, this includes acts eminently dangerous to others and showing depraved mind.
- Third-degree murder: Killing without intent but with a depraved mind and indifference to human life.
- Second-degree manslaughter: Negligent act creating an unreasonable risk of death or great bodily harm, or aiding suicide under certain circumstances.
- Failure to intervene: An officer’s omission to act when there is a duty and reasonable opportunity to prevent constitutional violations by another officer.
- Misuse of property under color of law: Using one’s official position or authority to deprive another of rights or to wrongfully take or withhold property.
Status and aftermath (evergreen context)
As of 2025, all four officers have been released from their initial state prison sentences; Chauvin and the others serve concurrent federal sentences with provisions for supervised release. No retrials occurred on the state counts. Civil settlements totaling hundreds of millions of dollars have been paid by the city of Minneapolis. Policy reforms include updated use-of-force guidelines, enhanced training on medical care and de-escalation, and expanded duty-to-intervene requirements in multiple jurisdictions, ensuring the case remains a long-term reference in policing standards.
For ongoing legal or personal status questions, consult primary court records or official correctional information, as release conditions and supervised terms are subject to judicial discretion and regulatory updates.
