The California man charged in the stabbing death of Cash App founder Bob Lee was accused of knifing other men almost 20 years ago, records revealed.

Nima Momeni, then 20, allegedly stabbed a pair of teenagers in what Albany police described as an altercation over drugs, the San Francisco Chronicle reported, citing newly-obtained police files.

Both victims, ages 19 and 16, survived with minor injuries, the outlet said.

One witness reportedly told police that the 16-year-old attacked Momeni first.

Though Momeni was investigated for assault with a deadly weapon, possession of drugs and possession of drugs with the intent to sell related to the incident, he was initially released due to lack of evidence and “‘conflicting statements.’”

The Alameda County District Attorney’s Office declined to press charges, The Chronicle said.

Momeni, an IT consultant, was charged with murder two months ago in connection with the April 4 stabbing death of Cash App founder Bob Lee, 43.

Prosecutors believe the two men got into an argument related to Lee’s relationship with Momeni’s sister, Khazar “Tina” Elyassnia.

Lee, who was divorced and had two young daughters, and Elyassnia allegedly partied together through the upper crust of San Francisco, which included booze, drugs, and sexual escapades.

Lee and Momeni were reportedly at a house party on April 3 when Nima confronted Lee, asking if he and his sister were “doing drugs or anything inappropriate,” prosecutors claim.

The men were then spotted together on surveillance footage leaving the Millenium Tower – where Tina lives with her plastic surgeon husband – in the early hours of April 4.

Within a few hours, Lee had been stabbed and left to die on the sidewalk. He later died on the operating table, and was found to have had cocaine and ketamine in his system.

Momeni – who friends say had struggled with drug use over the years – was arrested April 13 and charged with Lee’s murder. 

Elyassnia was in court one month later when he pleaded not guilty.

Legal experts told The Chronicle that news of Momeni’s 2005 accusations are an “interesting development” – and noted that it could be used by the prosecution if the defense tries to argue that he had never been violent in the past.

“The prosecution will be watching like hawks for an opportunity to bring it in,” Tom Kensok, a veteran prosecutor in Contra Costa County, explained.

“It’s something the prosecution will make some effort to explore and develop.”

In addition to the 2005 investigation, Momeni was cited for battery in Aug. 2022 after a woman told police that he grabbed her and pushed her at his Emeryville home.

Prosecutors also declined to prosecute this case, though it is unclear why.

Momeni’s original lawyer, Paula Canny, withdrew from the case late last month, CBS News reported. 

She was replaced by Miami-based criminal defense attorney Saam Zanganeh, who describes himself on Instagram as a “legal sicario.”
