Cash App founder Bob Lee was fatally stabbed by an IT consultant near downtown San Francisco after the two men got into an argument over the suspect’s sister, according to court documents obtained by NBC News on Friday.

The suspect — 38-year-old Nima Momeni of Emeryville, a suburb of San Francisco — drove Lee to a secluded area and stabbed him three times with a 4-inch kitchen knife, including twice in the chest, according to the documents. At least one of the stab wounds punctured Lee’s heart.
