Nima Momeni, the man accused in the fatal stabbing of tech executive Bob Lee, testified for the first time in his defense at his murder trial Wednesday morning.

Nima Momeni struggles — or refuses — to provide much detail about the stabbing death of Cash App founder Bob Lee.

For the first time since Nima Momeni was charged with murdering tech mogul Bob Lee, the accused killer told his side of the story on Wednesday. Momeni broke his silence in front of San Francisco jurors who will decide his guilt or innocence.
