Cash App founder Bob Lee regularly attended underground sex and drug parties — also frequented by some of San Francisco’s well-known and wealthiest residents — alongside the sister of the man accused of murdering him, according to a new report.

Prior to his death, Lee was a fixture in the Bay Area’s secret party scene, rife with drug-use and casual sex, known by participants as “The Life Style.” According to the Wall Street Journal, he was often spotted partying with Khazar Momeni, the wife of a well-known San Francisco plastic surgeon and the sister of Nima Momeni. Friends said the pair were in the midst of a casual relationship and sleeping together.

Lee was “hanging out with people who weren’t great people, and that was part of what happened in the end,” friend Dana Wagner told the newspaper.

“There are a lot of swingers, cheaters and liars in that crowd.”

The tech entrepreneur was stabbed to death in San Francisco on April 4 around 2:30 a.m. He was spotted stumbling through the streets and begging for help before he died during emergency surgery at Zuckerberg San Francisco General Hospital. He suffered several stab wounds, including to the chest and hip areas.

Hours earlier, Lee and Momeni reportedly had a spat about Khazar, during which Momeni asked if his sister “was doing drugs or anything inappropriate.” Police said the confrontation unfolded after Momeni came to pick up Khazar from a house party where she’d been drinking with Lee and another friend.

The 43-year-old Cash App founder allegedly told Momeni neither he nor his sister had done anything illegal — though a toxicology report later revealed he had ketamine and cocaine in his system at the time of his death.

Later the same night, Nima and Lee both arrived separately to Khazar’s apartment and left together at 2:04 a.m. in Nima’s white BMW. From there, Nima drove Lee to a “dark and secluded” street corner and stabbed him in a “planned and deliberate attack,” prosecutors said.

“Just wanted to make sure your doing ok Cause [I] know nima came wayyyyyy down hard on you,” Khazar wrote to Lee in a text following the confrontation, according to court documents.
