Cash App founder Bob Lee was confronted by Nima Momeni, the man charged with his murder, about Momeni's sister prior to a fatal stabbing in early April where Lee was killed, according to new documents that detail Lee's final hours.

Court records released on Friday included text messages and testimonial evidence that helped illuminate what happened in the early morning hours of April 4 when Momeni allegedly fatally stabbed Lee. Momeni asked Lee questions about Momeni's sister, and his sister texted Lee the night prior to the stabbing, after they had hung out with a group, prosecutors wrote in the documents.

According to the documents, Lee had been drinking with a group of friends that included Momeni's sister that night, and later that night Lee was confronted by Momeni. A friend who spoke to police said that the group were first at a house drinking during the day, and later went to Lee's hotel room.

"The conversation was about Defendant [Momeni] picking up his younger sister from the house where they had earlier met her on the 1500 block of Mission St," prosecutors wrote. "Witness 1 said Defendant [Momeni] was questioning Victim [Lee] regarding whether his sister was doing drugs anything inappropriate."

According to the witness, Lee told Momeni that his sister had not taken any substances and that "nothing inappropriate had happened."

Prosecutors said in the documents that camera footage showed Momeni arriving at his sister's apartment building at 8:31 p.m. on April 3, while Lee entered her building at 12:39 a.m. By 2:03 a.m., Lee and Momeni leave Momeni's sister's apartment in Momeni's White BMW Z4.

Momeni then drives Lee to a secluded corner, according to the documents. Video footage obtained by police show two figures matching earlier descriptions of Lee and Momeni speaking outside of the car for several minutes before a figure matching Momeni's description "suddenly" moved toward and fatally stabbed the other figure before quickly leaving in the BMW, prosecutors added. 

"Just wanted to make sure your doing ok Cause [I] know nima came wayyyyyy down hard on you," Momeni's sister wrote to Lee after the argument happened, according to the documents.

"Thank you for being such a classy man handling it with class," she texted Lee. "Love you Selfish pricks."

On Friday morning, San Francisco police searched Momeni's sister's apartment, per the Chronicle. Momeni was scheduled to be arraigned on a murder charge on Friday, but his hearing was delayed to April 25.
