The man accused of killing the tech executive Bob Lee on a secluded San Francisco street this month stabbed him three times with a kitchen knife, prosecutors said in court documents released on Friday.
The accused assailant, Nima Momeni, 38, had argued with Mr. Lee about whether anything “inappropriate” had happened between Mr. Lee, 43, and Mr. Momeni’s younger sister, prosecutors said, describing details of the police investigation in a motion to hold Mr. Momeni without bail.
During a brief court hearing on Friday morning, Mr. Momeni’s arraignment was put off until later this month.
Prosecutors said that Mr. Momeni, a tech consultant and entrepreneur, stabbed Mr. Lee, who was instrumental in creating the mobile payment service Cash App, on April 4 with the four-inch blade of a kitchen knife, including once through the heart.
He then threw the knife in a parking lot and raced away, leaving Mr. Lee, 43, “to slowly die,” the motion states.
