The Pulse nightclub shooting remains one of the deadliest mass shootings in modern U.S. history. The attack unfolded during the early hours of June 12, 2016, when a gunman opened fire inside the popular Orlando nightclub, killing 49 people and injuring 53 others before being fatally shot by police.
Years later, the tragedy continues to be remembered as a defining moment in the nation’s history, profoundly impacting the LGBTQ+ community, law enforcement practices, and conversations surrounding terrorism, gun violence, and public safety.
Gunman Opened Fire During Packed Latin Night Celebration
Nearly 300 people were inside Pulse Nightclub in Orlando, Florida, celebrating the venue’s popular Latin Night when the attack began shortly after 2 a.m.
Authorities said Omar Mir Seddique Mateen, armed with a semi-automatic rifle and a handgun, entered the nightclub at approximately 2:02 a.m. and began firing indiscriminately at patrons and employees.
As panic spread throughout the club, many people escaped through exits while others hid inside bathrooms, dressing rooms, storage areas, and other confined spaces in hopes of surviving the assault.
Police Response and Hostage Situation
Orlando police officers arrived within minutes after receiving numerous emergency calls reporting an active shooter.
The response quickly evolved into a hostage situation as officers worked to contain the scene while tactical teams prepared to enter the building.
Authorities focused on:
-
Rescuing trapped patrons.
-
Exchanging gunfire with the suspect.
-
Securing the nightclub and surrounding streets.
-
Establishing a safety perimeter.
-
Coordinating SWAT and emergency medical teams.
After several hours, members of the Orlando Police Department SWAT Team used an armored vehicle to breach part of the nightclub, allowing officers to rescue survivors. During the final confrontation, Mateen was fatally shot by police, bringing the attack to an end.
Investigation Into the Attack
The Federal Bureau of Investigation (FBI) led the federal investigation alongside state and local law enforcement agencies.
Investigators examined:
-
The gunman’s background.

Digital communications and electronic devices.
