TUCSON, Ariz. — A Maricopa man has been sentenced to 44 years in federal prison for the 2020 killing of Tohono O’odham Police Officer Bryan Brown, the U.S. Attorney’s Office announced Monday.
Carlos Maximilliano Galvan, 44, was sentenced on June 4, 2025, by U.S. District Judge James A. Soto after pleading guilty to second-degree murder.
The fatal incident occurred on August 27, 2020, after Officer Brown responded to a 911 call at the Desert Diamond Casino in Why, Arizona. The call involved a man who had crashed his vehicle into a handicapped parking sign and assaulted two casino workers by ramming their truck. When Officer Brown arrived, Galvan confronted him with a broken bottle in hand.
As Officer Brown tried to avoid the threat, Galvan jumped into the officer’s patrol vehicle and drove it directly at him and a Border Patrol agent who had arrived to assist. While the agent was able to avoid being hit, Galvan struck Officer Brown, killing him. Galvan then fled the scene in the stolen cruiser, intentionally crashing into two other Border Patrol vehicles on the way.
“This sentence represents our unwavering commitment to holding accountable those who commit violence against law enforcement,” said Jarod Brown, Acting Special Agent in Charge of FBI Phoenix. “We hope this brings some peace to Officer Brown’s family and fellow officers.”
U.S. Attorney Timothy Courchaine emphasized the broader impact of the attack. “This was not just a murder—it was an attack on justice itself. Officer Brown gave his life in service, and we honor that sacrifice.”
The case was investigated by the FBI’s Tucson Office, with prosecution led by Assistant U.S. Attorneys Frances Kreamer Hope, Alicia Renee Quezada, and Rui Wang.
