U.S. District Judge Paul Byron ruled to let an obstruction of justice charge against Noor Salman, the wife of Omar Mateen, stand.

She also faces a charge of aiding and abetting her husband, who killed 49 people a year ago at the Pulse Nightclub in Orlando, reports Vicky Behringer for CBS News.

Salman argued that the charge was filed in the wrong district, since the charge was for obstruction during an interview in Fort Pierce, but was filed in a different district that includes Orlando.

However, the judge stated that the offense also had an impact in Orlando’s district, and therefore were filed correctly.

Law enforcement officials believe Salman played a role in the attack, as she bought ammunition with Mateen and may have been with him when he cased the nightclub. They also communicated via text during the shooting.

Salman claimed that she tried to stop Mateen from committing the attack, but law enforcement wondered why she didn’t call police if she knew about his plan in advance. During the investigation, she was interviewed several times by the FBI.

Salman will be tried in March for both the obstruction and the aiding and abetting charges.
