A gunman drove a sedan through a fence into an outdoor lunch area at a Citibank office campus in the Tampa area on Wednesday, fatally shot a woman, and was then shot by a Citibank security guard during an exchange of gunfire in a cafeteria, Hillsborough County officials said^1,2,10.

Hillsborough County Chief Deputy Frank Losat said authorities received multiple 911 calls reporting a shooting around 12:11 p.m.^2,10. The Tampa Bay Times reported deputies arrived about a minute later and that Losat said the suspect was shot by the security guard at 12:13 p.m.¹⁰. The suspect was taken to a hospital and pronounced dead, Losat said².

Losat said the suspect crashed into outdoor seating where people were having lunch, then got out with a rifle². "Upon the car coming to rest, the suspect exits the vehicle with a rifle, approaches the female, and she is shot," Losat said². The victim's name was not released pending identification and next-of-kin notification^2,10.

Four people were taken to a hospital with injuries that were not life-threatening; officials said it was not yet clear whether they were struck by the vehicle or otherwise hurt^2,10,12. About 3,200 Citibank employees were on the property at the time^2,10.

Sheriff Chad Chronister said earlier Wednesday, based on preliminary information, that officials believed the episode was targeted². At the later briefing, Losat said investigators still had to work through details, including whether the suspect and the slain woman knew each other, and that information could change^2,12.

The Tampa Bay Times said 367 Hillsborough sheriff's deputies responded and that clearing the sprawling Sabal Park campus took about 2 1/2 hours¹⁰. An emergency alert later said the suspect was no longer an active threat and lifted a shelter-in-place order while urging the public to avoid the area¹⁰. Hillsborough Community College's nearby Brandon campus was locked down and later given an all-clear, a college spokesperson told the Times¹⁰.

Katie Doshi, Citi's director of corporate communications, said the company was aware of an incident at its Tampa site and was coordinating with law enforcement¹⁰. The Times said the campus has occupied land near East Dr. Martin Luther King Jr. Blvd. and Interstate 75 since 1998 and has more than 10,000 employees overall¹⁰.

Losat said the crime scene was large and could be processed into Thursday, with interviews of witnesses continuing well into the night². ABC News reported that a law enforcement source said ATF agents would respond². Names of the gunman and the slain woman had not been released^2,12.
