Man accused by Khazar Momeni tries to clear his name after Bob Lee trial
SAN FRANCISCO (KRON) — Jeremy Boivin's name came up nearly every day of Nima Momeni's murder trial. Testimony about Boivin cast him as a sinister key figure connecting Cash App founder Bob Lee with his killer and Khazar, Momeni's sister.
Prosecutors said revenge was the motive behind the April 4, 2023 slaying under the Bay Bridge. Momeni was an over-protective big brother who believed Boivin sexually assaulted his married sister, and Lee had 'inappropriate' relationship with her, prosecutors said.
Momeni testified that Boivin was a 'predator.' But Boivin never testified for the jury trial. He spoke out for the first time in an interview with Dateline that aired over the weekend.
'Bottom line is, I didn't do it. There was no sexual assault at any point,' Boivin told Dateline. He admitted to slapping Khazar on her buttocks, but denied doing anything sexual against her will.
Lee, 43, died from a stab wound through his heart. Momeni was convicted by a jury of second-degree murder. Khazar was the motive behind the killing, police and prosecutors said.
Lee founded the company Cash App, worked for Google as a software engineer, and served as an executive for MobileCoin. Khazar was among dozens of witnesses who took the stand for Momeni's 2024 trial in San Francisco Superior Court.

Khazar testified that Boivin gave her LSD and a 'date rape drug' GHB, because she passed out on his bed. 'I was becoming more and more vulnerable,' she said. Khazar told jurors the Boivin pulled her pants down and sexually assaulted her on April 3, 2023.
After she woke up face-down on his bed, Khazar cried as she called her brother for help and asked him to drive her home to Millennium Tower. Khazar admitted that she invited Boivin over to her luxury apartment in Millennium Tower — around the same time that Lee was stabbed to death — because she wanted more drugs from Boivin.
Boivin told Dateline that he developed an intimate 'physical relationship' with Khazar for 'many months' after Lee's death. He also claims Khazar called him to apologize for accusing him in front of jurors and news reporters.
Boivin was previously convicted of drug charges unrelated to the Momeni case. For the murder trial, he was most frequently referred to in the courtroom as 'the drug dealer' by witnesses and attorneys.
Lee's friends testified that the tech titan used drugs including cocaine and whippets at parties with his large circle of friends. The victim's tech friend, Carlos Whitt, told Dateline, 'Bob was just built different. He could do the parties, but would also be one of the number one engineers on the planet.'
Defense frames Bob Lee murder trial as 'average Joe' vs. tech star
Lee spent his last three nights alive partying with friends around San Francisco, including: Khazar, Boivin, and a nightclub DJ, Bo Mohazzabi. Khazar exchanged flirtatious text messages with the tech mogul and attended parties with him, trial evidence revealed.
Momeni's defense attorneys said Boivin was Lee's drug dealer. Court documents obtained by KRON4 show the two men were also close friends. Khazar testified that she had never met Boivin until two days before the homicide, when Lee introduced her to him. Khazar admitted that she heavily uses party drugs, including whippets.
Prosecutors said Momeni was enraged with Lee because he introduced Khazar to Boivin and left her alone with him. Assistant District Attorney Omid Talai told Dateline that the motive does not depend on whether Boivin actually sexually assaulted Momeni's sister. Instead, the motive depends on Momeni's belief that the assault happened, Talai said.
'Khazar is the engine that made this whole thing happen,' San Francisco Police Department Sgt. Brent Dittmer told Dateline.
In September of 2024, just weeks before the trial began, Boivin told Sgt. Dittmer that if he were forced to testify, he would not be willing to say much, court documents show. Boivin said he met Lee in 2019 at a nightclub and they became 'good friends.'
Boivin did not know that their phone call was recorded when he talked to Dittmer on the phone.
'Did you ever provide drugs to Bob?' the sergeant asked. 'I can't talk about that,' Boivin answered. Boivin said Lee was 'always in a good mood, and trying to help people out. I'd trust him with anyone, anything in my life. I'd leave my cats with him. He's a 100% a solid dude. He'd take care of whatever you needed.'
Boivin said Khazar's sexual assault allegations took a toll on his life. He said, 'I feel really upset about it. It's taken a toll on my life for sure. It's outrageously not true,' court documents state.
Lee's family described Khazar's testimony as 'fabricated' to paint a rosy picture of Momeni before jurors reached a verdict.
Momeni's five attorneys were paid by Khazar and her wealthy husband to build his defense case. Defense attorney Saam Zangeneh said his client's sister had zero credibility because she's a drug addict.
Lee's ex-wife told Dateline that she will never forgive Momeni, as well as Momeni's family members who she believes helped him after the murder. Krista Lee said the hardest part of losing Bob Lee is seeing the pain in their two children's eyes. Her children deserved to have their father in their lives, and Bob Lee should have died 'an old man,' Krista Lee told Dateline.

'The murderer robbed this world of a great mind,' Krista Lee said.
Momeni is facing up to 16 years in prison when he is sentenced on May 16. He remains locked in a San Francisco jail cell.
