ORLANDO, Fla. - Day two of the Orlando massacre and a community is still in mourning.
Orange Avenue remains closed as investigators collect as much forensic evidence as they can.
The FBI stated agents are in the process of reconstructing the shooting inside the club now that 50 bodies, including the gunman Omar Mateen, have been removed from the Pulse Nightclub.
Monday morning the FBI said 48 out of the 49 victims have been identified.
Orange Avenue remains closed between Grant Street and Kaley Street as investigators continue to dig for more clues in this deadly massacre.
Orlando Police released more details about the gun battle between officers and the suspect.
Chief John Mina said the situation became a crisis when they found out the gunman had dozens of hostages with him in the bathroom and found out Mateen had a bomb vest and other explosives.
"Officers made entry while the suspect was shooting,” said Orlando Police Chief John Mina.
“They engaged in a gun battle with the suspect, forced him to stop shooting and retreat to the bathroom, where we believe he had several hostages. At that time we were able to save and rescue dozens and dozens of people who were injured and not injured, and get them out of the club.”
During the three hour standoff with police investigators said a hostage negotiator started talking with the gunman, Omar Mateen to try and get him to surrender but refused.
Chief Mina said there were about fifteen people in the opposing bathroom where the gunman was holding hostages and he knew there was going to be an "imminent loss of life" and made the difficult decision to start the rescue operation and did an explosive breach. Chief Mina the explosive did not completely destroy the wall and used an armor vehicle to punch a hole.
From there that's where law enforcement agents were able to rescue dozens of people.
Despite the horror and sadness, Mayor Buddy Dyer said this will only make the community stronger.
“We will not be defined by the cowardly hater. We will be defined by how we respond, how we treat each other and this community has already stepped up to do that,” said Orlando Mayor Buddy Dyer during a press conference Monday morning.
