What happened to Bob Lee?
On 4 April 2023, Bob Lee tragically died after he was stabbed multiple times by Nima Momeni in San Francisco, California, USA. According to court records, earlier in the day on 3 April 2023, Bob attended a party where Nima's sister, Khazar Momeni, was in attendance.
While at the party, Khazar and other partygoers consumed alcohol and recreational drugs, including GHB. Although Bob had left the party earlier in the day, Nima, who came to his sister's rescue, interrogated Bob about the drug and seemed to place the blame on him.
At about 12:30 am on 4 April 2023, Bob decided to visit Khazar at The Millennium Hotel, where he met Nima. After a little more than an hour, Nima and Lee left the building and drove off together in a white BMW Z4 Roadster.
Nima is believed to have attacked Lee at about 2:00 am before speeding off. Within minutes, 911 responded to Lee's call for help, and he was rushed to San Francisco General Hospital, where he succumbed to excessive blood loss from the stab wounds, including one that punctured his heart.
