The call came in at 12:37 p.m. Wednesday. A 21-year old gunman, clad in a T-shirt that bore the image of four scythe-wielding grim reapers on horseback, wanted police to know that he had just opened fire in a bank in the small city of Sebring, Florida, police said.

“I have shot five people,” he told a dispatcher, according to a police statement. There were only five people in the bank at the time, police said, and they all died.

When the Sebring Police Department and the Highlands County Sheriff’s Office responded to the SunTrust Bank branch on U.S. Route 27, they said, they found the shooter barricaded inside. What followed was a tense standoff with police negotiators that ended when an armored police vehicle rammed into the bank doors, shattering their glass, video footage shows.

Police said in a statement that negotiators and members of the SWAT team “persuaded the suspect to surrender.” Video from the scene shows officers inching toward the broken glass with their firearms drawn. They soon emerged with the suspect in handcuffs.

“We are sorry to learn that we have at least five victims, people who were senselessly murdered, as a result of his act in this bank,” Chief Karl Hoglund said at a brief news conference late Wednesday afternoon in this city 80 miles south of Orlando.

He identified the man in custody as Zephen Xaver, 21, a resident of Sebring. Police said they were still investigating the motive for what the police chief called “coldblooded murder.”

Scott Dressel, a spokesman for the Highlands County Sheriff’s Office, said Xaver was being held at Highlands County Jail and had been charged with five counts of first-degree murder. It was unclear late Wednesday if Xaver had a lawyer.

Hoglund told reporters that investigators had not finished identifying the victims and had not notified the families of those they had identified. “This is a very dynamic and ongoing investigation,” he added.

Xaver had recently been training to work as a correctional officer at Avon Park Correctional Institution, a prison about 20 miles north of the bank where the shooting occurred, said Patrick Manderfield, a spokesman for the Florida Department of Corrections.

He was hired as a trainee in November and resigned Jan. 9, Manderfield said. He had no disciplinary record with the department.

Gov. Ron DeSantis, who traveled to the area Wednesday afternoon, posted a condolence message from him and his wife, Casey, on Twitter.

“This is a terrible day for Sebring, Highlands County and for the state of Florida,” DeSantis said. “Casey and I extend our most sincere condolences and sympathies to the families and loved ones of the victims. The people of Florida stand with the community of Sebring.”

The governor said the gunman was “an individual that needs to face very swift and exacting justice.”

Bill Rogers, chairman and CEO of SunTrust, said in a statement that the company was “working with officials and dedicating ourselves to fully addressing the needs of all the individuals and families involved.” He said the company was “deeply saddened” by the loss of life at the bank.

Sebring, a sleepy city of about 10,000 whose meandering borders are dotted with lakes, boasts a historic downtown and an international raceway. On Wednesday night, it was swarming with wailing police cars, buzzing helicopters and media vehicles.

Don Elwell, a member of the Highlands County Board of County Commissioners, said families of the victims had gathered at a hotel in town to wait for updates from police.

“We have a whole lot more questions right now than answers,” he said.

Both the shootings and the lack of information had left the community in shock, he said.

“For us — I have some family in Las Vegas, where there was that big shooting, and they said, ‘We’re sorry to welcome you to our club,'” Elwell said Wednesday, referring to a 2017 shooting that killed 59 people. “Obviously that was a different scale, but here in little Sebring it might as well be the same.”

The episode Wednesday is just the latest of several high-profile shootings in Florida that have roiled the state in recent months.

Last February, a young gunman barged into his former high school in Parkland, opening fire on terrified students and teachers and leaving 17 dead. In August, a man with a handgun killed two people at a video game tournament in Jacksonville before fatally shooting himself. And last fall, a man walked into a yoga studio in Tallahassee, and shot six people — two fatally — before killing himself.

Florida, which bears the official nickname the Sunshine State, is sometimes referred to as the Gunshine State because of its traditionally loose restrictions on firearms. But in March 2018, in the wake of the Parkland shooting, Rick Scott, who was then the governor, signed an array of gun limits into law that included raising the minimum age to purchase a firearm to 21 and extending the waiting period to three days.

It was the most aggressive action on gun control taken in the state in decades, and the National Rifle Association almost immediately sued.
