A gunman killed a Citibank employee and was then shot dead by an on-site security guard within minutes as thousands sheltered across the Tampa campus.

Story Snapshot

  • Deputies say the shooter targeted a Citibank employee before a security guard confronted and killed him.
  • Roughly 3,200 people were on the campus when the shooting unfolded, heightening the risk.
  • Emergency calls began at 12:11 p.m.; the guard engaged the gunman around 12:15 p.m..
  • Officials reported one woman killed, four non-life-threatening injuries, and the suspect dead.

Rapid Sequence From First 911 Calls To Guard Confrontation

Hillsborough County authorities said the first 911 calls from the Citibank campus came in at 12:11 p.m. on a weekday afternoon. By about 12:15 p.m., an armed security guard employed at the site confronted the shooter in a cafeteria area and exchanged gunfire, killing him, according to officials and local coverage of the briefing. Deputies described the event as an active threat during the response. Reporters at the scene relayed that the guard “stopped the threat,” quoting the agency’s leadership.

Officials said the gunman arrived in a vehicle, moved onto the grounds with a rifle, and shot and killed a woman before heading toward the cafeteria, where the security guard engaged him. Reporters covering the briefing said four additional people suffered non-life-threatening injuries. Authorities did not specify whether those injuries came from gunfire or the chaotic evacuation. The suspect died after the shootout with the guard, ending the active threat inside the complex.

High Occupancy And Large Law Enforcement Deployment

Deputies and local outlets reported that about 3,200 employees were on the property when the shooting began, which raised the risk to people in offices, hallways, and common areas. The Hillsborough County Sheriff’s Office sent a massive response, with reports citing 367 deputies deployed to the scene. Teams cleared the buildings within about two and a half hours, while workers evacuated to a reunification site and awaited updates from officials.

Agency leaders emphasized that the on-site security presence was key to stopping the shooter quickly while units were still arriving. The timeline described by officials shows a short window between the first emergency calls and the fatal encounter in the cafeteria. That rapid end to the threat lines up with the relatively limited casualty count that investigators shared during the day: one woman dead, four with injuries that were not life-threatening, and the gunman killed by the guard.

Investigators Describe A Targeted Killing And A Fast End To The Attack

Authorities told reporters the shooter appeared to target the woman who was killed before moving deeper into the complex. The security guard then engaged him inside the cafeteria space, where the fatal exchange occurred, officials said. Local coverage said the sheriff’s office referred to the situation as an active threat while also describing the initial killing as targeted, a distinction that helps explain both the urgency and the focus of the response.

Later reporting cited the sheriff’s office in stating the shooter had a grievance connected to a $2,500 debt and named the victim, which supports the targeted nature of the attack, though investigators were still processing evidence as they briefed the press. The campus remained closed to most activity as detectives gathered witness statements and reviewed security footage. Officials did not immediately release detailed medical information for the four injured workers or visitors.

How This Fits Broader Active-Shooter Patterns

The Federal Bureau of Investigation (FBI) defines an active shooter as someone actively trying to kill in a populated area, which can include a targeted workplace attack that threatens many others nearby. In recent years, some incidents have ended when security personnel or law enforcement intervened with gunfire, though that is not the most common outcome across all cases. The 2025 FBI review counted multiple resolutions, including shooters killed by security or police.

What This Means For Workers And Employers

This event shows how a single targeted grievance can endanger many people on a busy campus. The fast engagement by an on-site guard limited the time the gunman had to move and fire. For workers, clear drills, direct alerts, and exits matter. For employers, layered access controls, trained guards, cameras, and practiced lockdown steps can save minutes when seconds count. Local briefings stressed that the guard’s actions ended the threat while thousands sheltered or evacuated.
