A San Francisco coroner’s autopsy and toxicology report reveals tech mogul Bob Lee had multiple “party drugs” in his system when he was killed

A chief forensic toxicologist for the Office of the Chief Medical Examiner has done a toxicology test on Lee using blood samples. 

The blood tests detected:  cocaine; ketamine and norketamine, also known as “Special K”; alcohol; and Levocetirizine, an antihistamine.

According to defense attorney Paula Canny, “There’s a lot of drugs in Bob Lee’s system. I mean Bob Lee’s system is like the Walgreens of recreational drugs.” 

However, District Attorney Brooke Jenkins fired back, saying, “Whatever that toxicology test may show, Mr. (Nima) Momeni is guilty of murder.”

Jenkins said this is a common tactic defense attorneys use to smear a homicide victim’s character. 

“Regardless of whether somebody has, or has not done drugs, that does not give someone a license to kill them,” Jenkins told reporters at the courthouse Tuesday.

On April 4, at 2:36 a.m., Bob Lee, 43, called 911, reporting that someone stabbed him in the chest. San Francisco police officers found him unconscious and bleeding from three stab wounds at 365 Main Street. 

Lee was rushed to San Francisco General Hospital, where surgeons tried to save his life. 

“The subject was found to be pulseless and massive transfusion protocol began. The subject then underwent an emergency thoracotomy. The thoracotomy revealed two injuries to the heart,” the autopsy report states.

According to the report, Lee died on the operating table and was declared deceased at 6:49 a.m. 

His death classifies as a “homicide stabbing.” 

The defense and prosecutors both said they had not yet received a copy of the autopsy and toxicology report from the Chief Medical Examiner.

Jenkins told reporters Tuesday, “It bothers me that it was provided to you before it was provided to us. He has a family, he has children, who should not have to learn about these things through the press.”

Canny said the toxicology report will impact the case. Canny said, “Every recreational drug that a person could take was in (Bob Lee’s) system. That’s crazy that someone is running around on cocaine, ketamine. He didn’t die of a drug overdose. But put on your thinking cap. What happens when people take drugs? What do drug people act like? Not themselves … kind of losery, and make bad decisions and do bad things.”

Before Lee’s death, he spent hours hanging out with Khazar Elyassnia and friends drinking in luxury hotels and apartments. 

One of the hangout places was inside an apartment on Mission Street near Van Ness Avenue. The apartment is the residence of a suspected drug dealer. 

A witness told investigators that  Elyassnia’s brother, 38-year-old Nima Momeni talked to Lee after the group of friends had left the apartment. 

“(Momeni) was questioning (Lee) regarding whether his sister was doing drugs or anything inappropriate,” court documents state.

Lee tried to reassure Momeni that nothing inappropriate had happened.

Prosecutors said, around 2 a.m., Lee and Momeni left Elyassnia’s apartment together in a BMW. Momeni was secretly armed with a knife when he drove Lee to a secluded area of Main Street near the Bay Bridge and stabbed him in the heart. 

Momeni was arrested days later and was charged with one count of murder.

Jenkins declined to say if Lee, Elyassnia, and Elyassnia’s husband were tangled in a “love triangle.”

Canny said her client is not a murderer and that illegal drugs are a theme in the backstory. She told the press, “There is a huge backstory to this. More will be revealed later. Who would like to see their sister, who they are super protective of, potentially be drugged? Nobody. Any good brother would be upset about it.”
