Louisville shooting updates: 911 call from suspect's mom released

"There are no words to adequately describe the sadness and devastation that our Old National family is experiencing as we grieve the tragic loss of our team members and pray for the recovery of all those who were injured," Old National Bank CEO Jim Ryan said in a new statement Monday night.

Ryan and other members of the Old National leadership team have been in Louisville much of the day offering support to affected individuals and their families, and they will continue to be on hand to provide support in the days ahead.

"Obviously, this is an incredibly difficult situation, and our entire focus is on making sure that everyone affected has the support and assistance they need," Ryan said. "On behalf of everyone at Old National, I also want to acknowledge and thank Louisville law enforcement, the medical community and state and local officials for their incredible response to this tragedy. And finally, we ask you to please continue to pray for all those affected."

A fifth person has died following Monday's mass shooting at a Louisville bank, police said.

Louisville police identified 57-year-old Deana Eckert as the latest victim.

Louisville Mayor Craig Greenberg spoke with ABC News' Trevor Ault and pledged to make reducing gun violence his top priority in office, hours after four people, including his own friend, were gunned down inside a downtown bank.

"We have to take action. Today is a day for love and support to the victims… but this is life and death, so as mayor, this will continue to be our number one priority," Greenberg – who was a victim of a workplace attack last year, said in the interview that took place a block away the bank.

Greenberg called his emotions "raw."

“The second I got the alert that there was an active shooter going on, of course my mind immediately went back to the workplace shooting that I survived just over a year ago," he said. "I know many people who work in that building, so I was thinking about them and everyone that was there."

The suspected gunman who shot and killed four people at a downtown Louisville bank had recently been notified he was going to be fired from Old National Bank, law enforcement sources told ABC News.

Connor Sturgeon had interned at Old National Bank for three years before earning a full-time job in June 2021, sources said. He had been promoted in April 2022.

There was no immediate indication why he was notified he would be terminated, according to sources.

The suspect allegedly left a note to parents and friends indicating he was going to shoot up the bank, sources said.
