More than two months before she was arrested after a hit-and-run during which she was allegedly driving under the influence in San Francisco, the sister of the man accused of killing tech executive Bob Lee was arrested under similar circumstances in Marin County.

Khazar Momeni, 38, was arrested on suspicion of DUI in the Marin County town of San Anselmo on Sept. 22 after she “rammed” her white convertible Mercedes Benz into another car on Sir Francis Drake Boulevard around 5 p.m., according to a police report of the incident. 

No one was injured in the incident, but Khazar Momeni’s car was towed, and she was arrested on suspicion of driving under the influence, according to the Marin County District Attorney's Office and the incident report.

Khazar Momeni is a central figure in the murder case of her brother Nima Momeni and is expected to testify at the trial. That testimony could include details about her and Lee’s drug use and what happened in the hours before Lee’s death. 

She has thus far refused to cooperate with the police investigation into the killing, according to police. 

Prosecutors allege Nima Momeni stabbed Lee to death April 4 in San Francisco after the pair argued over Lee purportedly allowing Khazar Momeni to engage "inappropriate" behavior. The day before, Khazar Momeni was found distraught and half-naked at the home of Lee’s alleged drug dealer, Jeremy Boivin

Witnesses told police that Boivin supplied Khazar Momeni with a drug called GHB, which is also known as a date-rape drug, during a party at his apartment a day before the fatal stabbing.

That alleged drug use led Nima Momeni to threaten Boivin shortly before the stabbing, according to police testimony in the case.

Khazar Momeni, who did not respond to a request for comment, has not been charged in the Marin County matter, according to the Marin County DA's Office. 

The case remains under review, said the DA’s Office; the investigation is still open, according to the Central Marin Police Authority. 

Her second arrest for an alleged DUI was on Nov. 25 in San Francisco after police officers responded to a crash reported at Geary and Larkin streets on the edge of the Tenderloin at around 11:08 a.m. She was driving a white convertible Mercedes Benz.

Charges in her San Francisco case have yet to be filed, but Khazar Momeni is set to appear in court on Dec. 12.
