An autopsy report of Cash App founder Bob Lee, who was stabbed to death in the street of San Francisco last month, shows that his body had cocaine, ketamine, and alcohol before succumbing to his injuries.

The autopsy report also found that Lee had the anti-allergy drug levocetirizine in his system, according to New York Post reported. The drug is known to have bad reactions with alcohol and ketamine.

Nima Momeni, 38, the murder suspect and a Bay Area entrepreneur was due in court on Tuesday for his arraignment, which has been postponed twice now. It has been reported that a witness saw Momeni and Lee, 43, allegedly got into a fight on the evening of the incident after Momeni found the tech mogul using drugs with his sister.

Lee reportedly met up with Khazar Momeni, the suspect’s sister, who is married to a plastic surgeon, hours before his death, according to court documents. Khazar’s brother allegedly “came wayyyyyy down hard” on Lee but the latter “handled himself with class” according to a text exchange described by prosecutors in court filings.

The argument escalated into a situation that was out of hand and Lee was stabbed by Momeni. His autopsy found that he was stabbed thrice. He was seen in the CCTV footage stumbling down Main Street in San Francisco’s Rincon Hill neighborhood. Although he begged passersby to help him, none of them did and he ended up calling 911.

After being rushed to the hospital, the doctors performed an emergency thoracotomy, where they had to cut through the rib cage in order to treat his wounds, but the effort was in vain.

Police arrested Momeni at his Emeryville home April 13, across the Bay Bridge from where Lee called 911 on April 4.
