Santa Rosa murder charge follows fatal shooting of Joni Brown

A late-night shooting outside a Santa Rosa shopping center turned into a murder case in just three days, after Sonoma County prosecutors filed charges Thursday, June 11, against Dwight Kestler in the death of Joni Brown. Brown, 40, was identified by the Sonoma County Coroner’s Office as the victim in the city’s first homicide of 2026, and the fast charging decision suggests investigators believe they already have a strong evidentiary trail.

Police said several 911 callers reported hearing gunfire in the 3000 block of Marlow Road late Monday evening, near a shopping center in northwest Santa Rosa. Officers later said Brown was standing near the center around 9:15 p.m. when Kestler allegedly approached on foot wearing dark clothing and a facemask and fired multiple shots. Santa Rosa police initially said the shooting appeared isolated rather than random.

From there, the case tightened quickly. Investigators recovered a vehicle believed to be connected to the killing and a revolver. Police said they used security-camera footage and automated license plate reader cameras to track the car and locate Kestler the morning after the shooting. KRON4 identified Kestler as 56, of Clearlake, and reported that he was booked into the Sonoma County Main Adult Detention Facility on suspicion of murder and violation of probation. That report also said a search warrant was served at a residence associated with Kestler in the 3200 block of 8th Street in Clearlake, where additional evidence tied to the homicide was found.

A second arrest followed. KRON4 identified Jill Bynum, 57, also of Clearlake, as the other person taken into custody, with booking listed as accessory-after-the-fact and unrelated warrants. Police said a third occupant in the car was released after being determined not to be involved. By the time prosecutors filed murder charges, the shooting scene, the getaway vehicle, the weapon recovery, and the people tied to the car were already separating into different parts of the case file.

The filing also lands against a bigger local backdrop. Santa Rosa police said 2025 ended with 12 homicides, a 500% increase from 2024 and tied for the highest number on record, with arrests made in all 12 cases. The department also reported an 80% reduction in homicides in 2024, along with more seizures of ghost guns and illegal firearms. The Sonoma County District Attorney’s Office says it handles criminal prosecutions countywide with a staff of more than 128 employees and a budget of nearly $33.7 million, and Brown’s case now moves into that courtroom machinery with the core question still hanging over it: how much of the shooting night is already locked down, and how much still has to be proved.
