An 18-year-old has been arrested after allegedly killing two people during a bank robbery in Kentucky, and police say his social media posts led to his arrest.

Brailen Weaver is charged with armed bank robbery and firearms offenses that caused death, according to federal court records.

Weaver entered a branch of U.S. Bank in Berea on Thursday just before 2 p.m. and “immediately shot and killed a male victim” and then fatally shot a teller, according to an FBI affidavit filed in federal court Friday.

He checked multiple drawers in the bank and then fled, the affidavit said. Investigators have not said if any money was taken from the bank.

“While there is no longer imminent danger, we understand that the tragedy is far from over for the community,” Olivia Olson, special agent in charge of the Louisville FBI office, said at a news conference Friday.

“The only solace that we can offer is that this individual, who valued a stolen dollar more than two human lives, will be held accountable to the fullest extent of the law.”

Officials said Weaver could also face state charges related to the homicides. Court records say Weaver is 18, and officials said Friday he lived somewhere in Kentucky.

Authorities identified a silver BMW sedan on surveillance video and matched it to a car for sale by Weaver on Facebook, the affidavit said.

Investigators were also able to match clothing on the suspect to photos of Weaver on social media. Investigators said Weaver continued to post on social media after the robbery.

The FBI located Weaver’s car on I-75, and he was pursued at speeds over 100 mph (161 kph) Thursday night. He exited the highway into Lexington, where he exceeded speeds of 130 mph (209 kph) before crashing the car and fleeing on foot, the affidavit said.

Kentucky State Police Officer Justin Kearney said in a social media post Friday that a “person of interest believed to be involved in yesterday’s Berea bank robbery has been apprehended.”

The affidavit was written before he was captured so makes no mention of an arrest.

Rawl Kazee, a Lexington attorney identified in court records as representation for Weaver, did not immediately return a phone message later Friday morning.

Jason Parman, first assistant U.S. attorney for the eastern half of Kentucky, said in his 18 years as a prosecutor, he could not recall a death related to a bank robbery. Parman said it’s not uncommon for a bank robber to be armed and to threaten violence, but deaths are uncommon in his experience.

Bank robberies nationally have declined from 5,546 in 2010 to 1,263 in 2023, a decrease of 77%, according to the FBI’s annual Bank Crime Statistics report. There were no deaths associated with bank robberies in 2022 and 2023, the most recent year available for the data.

Law enforcement officials went door to door in search of information and surveillance video, as well as using helicopters, drones and dogs. The Lexington Police Department and county sheriff’s offices took part in the search, along with the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives.

Area schools went into lockdown for a while Thursday until campuses were deemed safe. Students were not allowed to go home on buses and had to be picked up by their parents, state police said.

U.S. Bank said it was working closely with law enforcement and committed to supporting the victims’ families and bank colleagues. The small bank branch in the quiet community of Berea is located just a mile from Berea College and its campus that dates back to the 1850s.

“We’re deeply saddened by the tragic event that took the lives of two of our employees at our Berea, Kentucky branch earlier today,” the company said in a statement Thursday. “Our hearts go out to the families of the victims, our colleagues and the entire Berea community.”

Berea is about 36 miles (58 kilometers) south of Lexington.
