San Francisco, California — A 36-year-old man has been charged in connection with an alleged sexual assault involving a 21-year-old woman in San Francisco’s Bayview District. Prosecutors say the woman was unconscious when the alleged assault began and reported that she was unable to consent.
San Francisco Prosecutors File Charges Following Bayview Incident
The alleged incident occurred on September 26, 2026, near Bayshore Boulevard and Industrial Street. According to the San Francisco District Attorney’s Office, the woman reported waking inside a tent while David Vonstetten was allegedly sexually assaulting her.
Prosecutors said the two did not know each other before the incident. The woman reportedly left the tent, went down the hill, and found a witness who helped her contact the police.
Responding officers located Vonstetten and took him into custody, while the woman received medical treatment at the scene.
Prosecutors announced charges on October 7, including sodomy involving an unconscious or intoxicated person, sodomy by force, sexual battery by restraint, and felony false imprisonment. The investigation remains active, and the charges are allegations unless proven in court.
What California Law Says About Consent and Sexual Assault Claims
California law recognizes criminal offenses involving sexual activity when a person is unconscious, intoxicated to the point of being unable to consent, subjected to force, or restrained. The charges filed in this case include offenses under Penal Code Sections 286, 243.4, and 236.
Beyond a criminal prosecution, survivors may have separate civil rights after a sexual assault. Depending on the circumstances, a civil claim may seek compensation for losses such as:
- Medical and counseling expenses
- Lost earnings or employment-related losses
- Emotional distress and mental suffering
- Pain, suffering, and other non-economic harm
For qualifying adult sexual assault claims, California Code of Civil Procedure Section 340.16 generally provides up to 10 years from the assault, or three years from discovery of a resulting injury or illness, whichever is later.
