OPEN RECORDS SUMMARY :

n 08/13/2025, at approximately 10:12 p.m., Santa Rosa Police Department officers responded to a residence in the 900 block of Keegan Drive after a woman reported that her ex-boyfriend, 20-year-old Matteo Alexander Ramirez-Santos, was inside the home with a firearm. The woman, the couple's two-month-old child and her parents had left the residence before police arrived. She told officers Ramirez-Santos had pulled her hair, struck her in the back of the head with a gun and pointed the weapon at her head while threatening to kill her and responding police officers.
Ramirez-Santos remained barricaded inside the residence. Santa Rosa Police SWAT and hostage negotiators responded around midnight and attempted for more than six hours to persuade him to leave the house. Police said Ramirez-Santos did not cooperate with negotiation attempts and continued making threats through telephone calls, text messages and social-media communications with friends and relatives.
At approximately 4:53 a.m. on 08/14/2025, SWAT officers deployed chemical agents into the residence. Approximately two minutes later, Ramirez-Santos appeared at the front doorway holding an object. Investigators said video evidence showed him extend his left hand through the doorway and fire a handgun toward officers before coming out of the house and moving toward the police positions while still carrying the weapon. Officers warned that he was armed.
Santa Rosa SWAT Officer Sean Keaney was positioned in the turret of an armored rescue vehicle in front of the residence. Keaney fired one round, striking Ramirez-Santos. A SWAT tactical medic immediately provided medical treatment, but Ramirez-Santos was pronounced dead at approximately 4:57 a.m. Investigators recovered a loaded revolver near Ramirez-Santos, and the subsequent district attorney review reported evidence that the revolver had been fired.
The Sonoma County Sheriff's Office conducted the independent criminal investigation, including review of body-worn camera footage, surveillance recordings, physical evidence and witness statements. Santa Rosa Police also initiated a separate administrative review. Keaney was placed on paid administrative leave under department critical-incident procedures. At the time of the shooting, Keaney had more than 11 years of law-enforcement experience, including approximately four years with Santa Rosa Police and previous service with the Oakland Police Department.
On 04/24/2026, the Sonoma County District Attorney's Office announced that Keaney would not face criminal charges. Prosecutors concluded that Keaney reasonably believed deadly force was necessary to protect himself and other officers from an imminent threat of death or serious bodily injury and determined that the shooting was legally justified.
