The trial of Noor Salman, the wife of the Pulse nightclub shooter, starts Thursday, and it could answer some long-standing questions about the attack that killed 49 people.
Salman is charged with aiding and abetting the support of a foreign terrorist organization and obstruction of justice. She could spend the rest of her life in prison.
So here's what you need to know: Prosecutors say Salman signed a statement saying she knew what her husband was doing when he left for Orlando. They also say she went with him to case the nightclub and helped him with a cover story.
Her attorneys say the statement was a result of hours of interrogation and that she signed it so she could go home. They also say she was in a violent relationship and was forced to help him.
The trial is expected to last for weeks.
