On day four of the Noor Salman trial, attorneys questioned an FBI agent at the center of the prosecutors' case on Monday.

Noor Salman is accused of helping her husband Omar Mateen plan the deadly June 2016 attack at Pulse nightclub that killed 49 people. 

Special Agent Ricardo Enriquez testified that Salman told him Mateen became obsessed with watching violent jihadist videos two years before the Pulse attack.

Salman reportedly told FBI agents hours after the shooting that she was concerned her husband was planning an attack.

However, defense attorneys say that does not mean she helped Mateen plan it.

FBI agents who interviewed Salman hours after the attack say she made odd statements including asking when she would get money from her husband’s bank account. They also say Salman was emotionless when she was told that her husband was dead.

Defense attorneys say the agents are inconsistent with their testimony.

They allege the agent planted information into statements given by Noor Salman, by saying that the agent knew details about the case and told those details to Salman, which is how she knew about details like Disney, Pulse and Orlando. 

Jurors also saw photos from the search of the couple’s Fort Pierce home and details about the forensic review of the desktop and laptop taken from their apartment.

Past internet searches seem to support Noor Salman’s initial statements to the FBI that her husband spent about two years watching graphic and violent online ISIS videos.

While prosecutors say they are building proof that shows Noor Salman intentionally helped her husband plan the attack, family members say they don’t believe there’s any case to be made.

“Even if those confessions were true, which I don’t believe they’re true, there is no evidence that she aided and abetted him. The government hasn’t shown that yet," said Susan Clary, Salman family spokeswoman. "Maybe they haven’t shown their hand, but I will argue we’re well into trial, and they should be wrapping up there case in the next few days, and they just haven’t proven it.”

David Haas, of Haas Law Firm, shared his thoughts about the case with Spectrum News.

"What the jury will be instructed is the element government has to prove is that she knowingly aided and abetted the attack. Knowing about the attack is just one part of it, aiding and abetting is what she's actually charged with doing, and there's a difference," he said.

Prosecutors have to prove that Noor Salman not only knew about the attack, but helped her husband plan it. 

The trial continues Wednesday morning.
