Unveiling Tech Executive Bob Lee’s Story Ahead of NBC Dateline
On April 4, 2023, emergency services received a 911 call from a San Francisco street. The caller, weakened and saying “help me please,” collapsed beneath the Bay Bridge.
First responders found him with multiple stab wounds and severe blood loss. He still had his wallet and watch, which suggested the attack was not a robbery.
The victim and his career
Bob Lee was 43 at the time of his death. He built a reputation as a prominent Silicon Valley engineer and leader.
Lee worked on the Android operating system during his time at Google. He later helped develop Cash App and served as chief technology officer at Square, now Block.
In 2021, he joined MobileCoin as chief product officer. He moved from St. Louis to San Francisco, then to Miami in 2022. He often returned to visit his two children.
The night of the killing
Lee spent the evening of April 3, 2023 with friends. Those friends included Khazar Momeni and her brother, Nima.
The group had used drugs, including cocaine and GHB. Khazar said she felt assaulted at a friend’s apartment, which led to a confrontation later.
Surveillance footage places Lee and Nima together before midnight. Nima drove Lee to a Main Street area under the Bay Bridge that night.
Lee suffered three stab wounds. One struck his hip. Two reached his chest, including wounds to the heart and lung.
He called 911 at about 2:30 a.m. He walked unsteadily and collapsed near an apartment building. A 4-inch paring knife was found nearby.
After roughly four hours of surgery, Lee died on the operating table. A toxicology report found low levels of cocaine, alcohol, and ketamine, which investigators said did not cause his death.
Investigation and arrest
San Francisco police treated the scene as a violent assault rather than an opportunistic robbery. Detectives noted that Lee’s valuables remained on him.
Investigators matched the blade to a kitchen knife owned by Khazar Momeni. Surveillance also showed a BMW leaving the area at high speed.
Police identified 40-year-old IT consultant Nima Momeni as a suspect. Authorities arrested him outside San Francisco on April 13, 2023.
Officials said the dispute involved protection of Khazar and concerns about drug use. Investigators deliberately delayed correcting early speculation about a random attack.
Trial, verdict and aftermath
The trial opened in October 2024 at San Francisco Superior Court. Prosecutors argued the attack was planned and violent.
The defense said Lee drew a knife first and that the stabbing was self-defense. After seven weeks of testimony, the jury deliberated seven days.
On December 17, 2024, jurors found Nima guilty of second-degree murder. He was acquitted of first-degree murder.
He faces a sentence of 16 years to life. Sentencing remains pending while new attorneys seek a retrial and full transcripts are prepared.
Family and public response
Lee’s ex-wife, Krista, and their two children, Scout and Sirius, attended portions of the trial. The family described him as generous and devoted to his children.
Scout said the 911 audio remains deeply upsetting. The case drew wide attention because Lee was a visible technology executive.
