Hillsborough County Sheriff Chad Chronister has identified the gunman in Wednesday's deadly shooting at a Citibank campus near Tampa as 35-year-old Jacob Pearson of Orlando. The victim was 41-year-old Leanne Selman of Palm Harbor, a nine-year Citibank employee who worked as a learning advisor for the company's Security and Investigative Services division. According to the sheriff, Pearson crashed his car through a courtyard gate shortly after noon and shot Selman, who he said had no connection to Pearson and was simply in the wrong place at the wrong time. Pearson had no prior criminal record, and he died at a hospital after a Citibank security guard exchanged gunfire with him inside the complex. Detectives have not said why he singled out Selman or whether he was targeting anyone else.

The sheriff said the violence appears to trace back to a court case over a $2,500 delinquent Citibank payment, and that Pearson phoned a law firm handling the collection that morning and made threats. Orlando police went to his home for a welfare check after the call but did not find him there, and his wife has been cooperating with investigators. Chronister praised the guard, John Fraley, a Marine Corps veteran, as a hero and said the response likely prevented far more casualties, with about 3,200 employees on the campus at the time. Four other people sought medical treatment after the shooting, but the sheriff said none were hurt by gunfire. Because Pearson died, there will be no trial, but investigators are still working to piece together what happened and how the warning signs unfolded.
