Closing arguments began Monday morning in the San Francisco murder trial of Nima Momeni, the man accused of fatally stabbing tech executive and Cash App founder Bob Lee.

A San Francisco jury began deliberations Wednesday after hearing six weeks of evidence in the Nima Momeni murder trial. "We will all be very tense for the next week or two or however long it takes," said Lee's ex-wife Krista Lee.

Nima Momeni is accused of stabbing and killing Bob Lee but his defense said during closing arguments he had no motive and that the prosecution is using misleading DNA evidence.
