A gunman who killed a woman before being fatally shot by a security guard at Citibank’s sprawling office complex in Tampa targeted the campus because he was angry over a $2,500 debt collection, a sheriff said Thursday.

About three hours before Wednesday’s shooting, Jacob Pearson called an attorney affiliated with Citibank and threatened violence, Hillsborough County Sheriff Chad Chronister told a news conference.

On the phone, Pearson demanded that the lawyer cancel a court hearing over Pearson’s unpaid credit card debt “unless you want me to go over there with my AR-15, my bulletproof vest and my insanity,” Chronister said.

The sheriff said Pearson, 35, had no criminal history. Pearson’s father, Richard Pearson, told The Associated Press that he had never seen an indication that his son was capable of carrying out a violent shooting.

Gunman targeted Citibank, but had ‘zero connection’ to the victim

The attack unfolded as many of the 3,200 employees at Citibank’s campus in suburban Tampa were at lunch.

Pearson drove from his home in Orlando to Tampa, about 90 miles away, crashed his car through a fence at the campus and plowed into a courtyard where employees were eating, Chronister said.

The sheriff said Pearson got out of his car with a rifle and shot the first employee he saw. His rifle jammed after three shots, he said, and the gunman then retrieved a handgun from his car and again shot the same person, who died.

She was identified as 41-year-old Leanne Selman, who worked in human resources.

Selman had worked for Citibank for nine years and was “a beloved employee,” said Ed Skyler, spokesman for Citibank parent Citigroup. The sheriff said there was “zero connection” between Selman and her killer.

“He was there intent on one purpose, and that purpose was to hunt any human being he could find and kill them,” Chronister said.

As employees scattered to flee the gunfire, Pearson entered the building and walked through a cafeteria. An executive who is part of Citibank’s armed security team shot the gunman five times before he could hurt anyone else. Pearson was pronounced dead at a hospital.

The violence could have been far worse, the sheriff said. Pearson brought 90 rounds of ammunition to the campus, he said, but fired just 15 times before he was stopped.

No one else was shot, the sheriff said. Four people were treated at a hospital for minor injuries from fleeing and medical concerns such as chest pains.

Selman’s father declined to comment when reached by phone Thursday.

Deputies headed to Citibank campus after the threat

Chronister said Citibank’s security team and law enforcement were already on the lookout for Pearson after the attorney he called Wednesday morning reported the threat.

He said police went to Pearson’s home in Orlando, but were told by his wife that he had already left. In Tampa, Hillsborough County deputies had just arrived at the Citibank complex to provide extra security when the gunman opened fire.

Court records in Orange County, where Orlando is located, show Citibank filed a complaint against Pearson on Oct. 23, saying he owed $2,556.40 in credit card debt. Pearson’s bill for that amount was dated July 4, according to the court documents. The court issued a summons for Pearson to appear at a hearing Feb. 15.

Sheriff’s investigators wrapped up evidence gathering at the Citibank complex by early Thursday. But Tampa employees can work remotely for now, said Skyler of Citigroup.

“We will not be demanding people return to the scene of this incident on Monday or in the very near future,” Skyler said. “It’s really important for us to recognize the traumatic events that our colleagues experienced.”
