The Clearlake man accused of killing 40-year-old Joni Brown outside Santa Rosa’s Rosewood Village shopping center is headed for trial, after a judge ruled there is enough evidence to keep the case moving. Police have said the June 8 shooting, which unfolded in the parking lot of the Marlow Road complex, was Santa Rosa’s first homicide of 2026, and it quickly spun up an intensive investigation that produced surveillance leads and vehicle evidence within hours. The defendant has pleaded not guilty and faces a special lying-in-wait allegation that could bring far harsher penalties if a jury ultimately finds it true.
Investigation and arrests
According to the Santa Rosa Police Department, multiple 911 callers reported gunfire at about 9:15 PM on June 8 in the 3000 block of Marlow Road, and bystanders started CPR on Brown before officers and medics arrived. Detectives then pulled security footage from nearby homes and businesses, identified a suspect vehicle by the next morning and used an automated license-plate reader to help track it. A Sonoma County deputy later stopped the car and detained three occupants.
Police said a search of the vehicle turned up a revolver, and officers followed up with a search warrant at a Clearlake residence. One occupant, 56-year-old Dwight Kestler of Clearlake, was booked on suspicion of murder and a probation-violation charge. A second occupant, 57-year-old Jill Bynum, was arrested on suspicion of being an accessory and on unrelated warrants.
What prosecutors told the judge
At a preliminary hearing, a Sonoma County judge ruled there was sufficient evidence to hold Kestler for trial and to let prosecutors pursue a lying-in-wait special circumstance, The Press Democrat reported. Court filings and coverage say Brown suffered multiple gunshot wounds, and Kestler has entered a not-guilty plea. Prosecutors told the court they intend to move ahead with first-degree murder charges that include the special allegation, signaling they are treating this as a high-stakes case.
Timeline and evidence
Police and local reporting describe a fast-moving timeline in the hours after the shooting, with investigators relying heavily on automated license-plate readers and security cameras to zero in on the suspect vehicle before the traffic stop that produced the revolver and justified a Clearlake search warrant. The San Francisco Chronicle highlighted the quick coordination between the Santa Rosa Police Department and the Sonoma County Sheriff’s Office, which helped lead to arrests in less than a day. Officials say they are still reviewing video and other leads, and the case remains under active investigation.
Victim and community
Friends and neighbors described Brown as a Sonoma County native, a mother, and someone who regularly volunteered to help people experiencing homelessness and those affected by wildfires, according to reporting in The Press Democrat. Her killing has prompted an outpouring of condolences, along with renewed calls for anyone with footage or information to contact investigators.
Legal implications
The lying-in-wait allegation is one of several special circumstances listed under California law that prosecutors can attach to a first-degree murder charge. If a jury or judge finds such a special circumstance true at trial, it can make a defendant eligible for life without the possibility of parole or other heightened penalties. For more on how the special circumstance is defined and proved in court, see California Penal Code §190.2 and the CALCRIM jury instruction on lying in wait.
What’s next
Kestler remains in custody while prosecutors prepare for trial, and court records do not yet list a trial date. Investigators have asked anyone with residential or commercial security footage from the area, or any other information about the killing, to contact the Santa Rosa Violent Crimes tipline, and the police release includes the tipline number for those willing to come forward.
