Santa Rosa, CA – A Santa Rosa woman will be sentenced next month for her involvement in the shooting deaths of two young women in a Napa neighborhood last year.
Judith Adolph, 20, pleaded no contest on Thursday to several charges, including assault with a semiautomatic rifle and being an accessory. The plea means that Adolph accepts the conviction without admitting guilt. Her sentencing is scheduled for April 1 in Napa County Superior Court.
On the same day, two other individuals charged in the case—Jonathan Nicholson Jr., 23, of Vallejo, and Jessica Whitten, 20, of Santa Rosa—are due in court for a hearing that will determine whether they will stand trial. Nicholson and Whitten both face charges of murder, and Whitten is additionally charged with being an accessory after the fact.
The shooting occurred on Riverside Drive, a residential street near the Napa River, in the summer of 2024. According to police, the victims—Aileen Villasenor, 19, of Rohnert Park, and Sasha Mufich, 17, of Napa—were shot during an altercation. One of the victims died at the scene, while the other succumbed to injuries at a hospital shortly afterward.
Investigators revealed that Adolph and the two other suspects had gone to the area with the intention of confronting one of the victims. During the confrontation, Adolph was reportedly stabbed by one of the victims. Authorities allege that Nicholson, wearing a mask, then chased the victims and opened fire. Whitten is accused of driving the car that the suspects used to flee the scene.
Neighbors who discovered the victims called 911, and security cameras in the area helped identify the suspects. All three were arrested days later, and after months of delays, they pleaded not guilty to the charges in December. They have remained in jail without bail since their arrest.
The upcoming hearing for Nicholson and Whitten is expected to last up to four days. The legal proceedings are set to reveal further details about the case, as both suspects face serious charges in connection to the double homicide.
As the case continues, the families of the victims remain in mourning, while the legal process unfolds in Napa County Superior Court.
