Accused murderer Nima Momeni returned to the witness stand Monday morning answering written questions submitted by jurors about the night he stabbed Bob Lee in April 2023.Momeni was in his third day of testimony Monday as his trial enters its sixth week, after a combative day Thursday answering questions under cross-examination by lead prosecutor Omid Talai. Momeni shot back questions at Talai and appeared visibly agitated, according to multiple sources."When you cut me off and ask questions, did you do that when you talked with Bob?" Talai asked at one point.Momeni told jurors that he was only trying to defend himself the night of the killing, and that Lee pulled the knife on him after he made a "bad joke." That alleged joke, which was more of a cutting remark, was Momeni telling Lee that if it was his last night in town, he would be with his family and not "fucking around in strip clubs."It seems like an odd thing to say at 2 am — telling a guy to go be with his ex-wife and kids — but maybe that is the "joke" part.Momeni also contends that he was unaware that Lee was hurt when the two parted ways.On Monday, the day began with Momeni answering written questions from the jury. As KTVU reports, those questions included a couple obvious ones, like "Why didn't you call the police after Mr. Lee attacked you and why didn't you, for example, pursue an assault case against him?"Momeni reportedly responded, "I knew who he was. He seemed fine as he walked away. I was fine. I called the only person I knew, my sister, and told her don't let him in the house. Everything seemed fine."Given that he had to toss away a bloody knife, it seems implausible that he would have thought everything was fine. But jurors asked about the knife as well."Did you grip the handle (of the knife) at any point during the altercation?" they asked. Momeni said, also implausibly, "Not during the altercation. I just picked it up from the ground."Police earlier presented evidence that only Momeni's DNA was found on the handle of the knife, and only Lee's DNA was found on the blade.Jurors also asked, per KTVU, "Did you hear Bob Lee's 911 calls for help?"Momeni says, "He was quiet when he walked away from me. He just walked away from me. There was no communication when he left."Another juror question, referring to the beer that Lee allegedly spilled in Momeni's car, asked "The beer can that was spilled in your car, what happened to the can?"Momeni responded that he tossed it away when he got home, as KRON4 reports.There had been earlier testimony that Momeni and Lee had done some cocaine together while in the car, and/or previously in Khazar Momeni's apartment. A juror asked, "You mentioned you had a bump of cocaine and had some beers. Were you high? Were you under the influence of drugs or alcohol?""No," Momeni replied, per KRON4. "I did a small bump of cocaine and had a beer with him. But it did not affect me.""When you got home after the altercation, did you notice you had blood on your hands?" asked another juror."I checked my hands, my jacket, there was no blood."Still another juror asked if, when Momeni called his sister to tell her about the altercation with Lee, he told her about the knife."I did not mention the knife," Momeni said, per KRON4. (An odd omission!)Astutely, another juror asked what sister Khazar Momeni meant when she said, "Just wanted to make sure your doing ok. Cause i know nima came wayyyyyy down hard on you." The juror asked "You don’t know what your sister meant, that you came down 'way hard' on him?""No. At no point I came down hard on him. There was nothing between me and Bob," Momeni replied, per KRON4.Momeni was also questioned by the jury about when he texted his mother and brother-in-law, Dino, the next morning, telling them about Lee and Boivin being 'serious offenders' who he wanted investigated for rape, and he still did not mention the knife attack. He had no answer for that, and only said that he did not mention the attack or the knife.Momeni was excused by the judge after finishing the jury's questions on Monday, however he remains subject to recall for further testimony, as KRON4 notes.The defense's next witness to take the stand Monday afternoon was former San Francisco Police Department officer Steven Pomatto, who investigated the case for the defense team. He supports the defense's theory of self-defense, and noted that the number of stab wounds — only three — was "odd," as there are usually more when two individuals are in a fight.Previously: On Witness Stand, Nima Momeni Says a 'Bad Joke' Caused Lee to Suddenly Try to Stab Him
