A Florida judge will consider whether more 911 calls made during the Pulse nightclub shooting should be made public.

A judge on Monday ordered all audio of gunman Omar Mateen's 911 calls released, WFTV learned. The judge said that she needed to listen to the other 911 calls before making a decision.

Circuit Judge Margaret Schreiber listened to arguments from attorneys for the city of Orlando and attorneys for more than two dozen news outlets.

The hearing became a forum for family members to express their frustration over the lack of information released about the investigation. Many of the half dozen family members and their representatives who testified Monday said they want more information about the shootings on June 12 that left 49 people dead at Pulse Nightclub.

The FBI has offered no indication of when the probe into the shooting, that also left 53 people wounded, will be complete.

Media groups want 911 calls released so the public can evaluate the police response to what has been deemed the worst mass shooting in modern U.S. history.

City officials have released two-thirds of the calls. They have refused to release more than 200 calls placed to and from the nightclub during the three-hour massacre on June 12.

The city of Orlando said the 232 calls depict suffering and shouldn't be made public.
