The wife of Orlando attacker Omar Mateen has told federal agents she tried to talk her husband out of carrying out the attack, NBC News revealed on Tuesday.

According to the report the wife, Noor Zahi Salman, told the FBI she was with her husband when he bought ammunition and a holster, several officials familiar with the case said.

She also told the FBI that she once drove him to the gay nightclub, Pulse, because he wanted to scope it out.

Mateen opened fire at Pulse early Sunday, leaving 49 dead and 53 injured. 27 seven victims remained hospitalized Tuesday. Six were in critical condition, according to hospital officials who said the death toll was still at risk of rising because one or two of those patients were “profoundly ill.”

According to NBC News, authorities are considering filing criminal charges against Noor for failing to tell them what she knew before the brutal attack, but no decision has been made.

She is cooperating with investigators, several officials told the network.

Mateen’s father has claimed that the shooting was in response to his son’s anger over seen two men kissing several months ago.

Omar himself called police during the attack and told them that he had pledged allegiance to ISIS. The terror group happily claimed credit for the attack in the aftermath.
