The Louisville Metropolitan Police Department on Tuesday released body camera footage from the Monday mass shooting at Old National Bank that left five people dead and eight injured, showing how responding officers were able to shoot and kill the gunman from outside the building.

The graphic, nine-minute footage includes video from the two initial responding officers, as well as a bystander video taken from across the street. The footage begins with body camera video from Officer Nickolas Wilt, the rookie who remains in critical condition after the gunman shot him in the head.

Wilt and his training officer, identified as Cory "CJ" Galloway, arrived on the scene approximately three minutes after officers were first dispatched, authorities said during a Tuesday press conference. As soon as the officers pulled up to the bank, the gunman began firing at them still inside their police car, the video shows.

After exiting the vehicle, Wilt and Galloway walked up a set of outdoor stairs, preparing to try and confront the shooter, police said. But because of the gunman's vantage point from inside the bank, the interior of which was shielded by non-reflective glass doors, the shooter could see the officers approaching, even though they were unable to see inside him the building, police said.

As a result, the gunman fired at the two approaching officers, and shot Wilt in the head, causing him to fall to the ground. During the encounter, Galloway also sustained a small gunfire injury, police said, and video shows him falling down a set of stairs, where he took shelter behind a tall planter for approximately three minutes, attempting to spot the shooter inside the building while he waited for backup.

When other officers did arrive on the scene, they attempted to find Wilt and give medical care to the fallen officer, the video shows.

All the while, the gunman was still firing at police. During the encounter, however, the shooter shot out some of the bank doors' glass, giving Galloway a vantage point to fire the death shot from several feet away, authorities said while showing the body camera footage on Tuesday.

"The response wasn't perfect, but it was the exact response we need," Deputy Chief Paul Humphrey said during the press conference.

No other people inside the bank were injured after police arrived on the scene, Humphrey added.

The body camera footage blurs out both Wilt's body and the gunman's dead body, but police did release two security footage images of the gunman holding his AR-15-style weapon inside the building prior to the shootout.

Police on Tuesday also confirmed that the 25-year-old gunman was a current employee at the bank. Authorities have not yet released a motive.

Authorities identified the victims as Joshua Barrick, 40; Thomas Elliott, 63; Juliana Farmer, 45; James Tutt, 64; and Deana Eckert, 57.

Louisville Metro Police Department Chief Jacquelyn Gwinn-Villaroel told WDRB-TV on Tuesday that the department is feeling "hopeful" about Wilt's condition. The young officer, who was only 10 days out of training remained in critical but stable condition on Tuesday morning, the police chief said.
