BEREA, Ky. (AP) — A person of interest has been taken into custody in connection with the fatal shootings of two bank employees during a robbery, a Kentucky state trooper said Friday.

The person is “believed to be involved” in the bank robbery in Berea on Thursday, Trooper Justin Kearney posted online.

A man wearing a gray-white hoodie, gloves and a mask entered a branch of U.S. Bank in Berea and shot a male and female employee on Thursday, state police said.

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.

“This was a team effort,” Kearney posted Friday morning.

He did not provide further details.

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.

“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. “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.
