Ed. note: To protect the privacy of the US Bank employees who witnessed the homicides of Breanna Edwards and Brian Switzer, The Edge is withholding their names, and the details of the mortal wounds sustained by the victims.

He was early, so he waited in the car and checked emails on his phone. Eventually, Craig Williams of Berea, got out of his car and made his way to his appointment with his banker. It was Thursday, April 30, just before 2pm. Williams had just opened the first set of double doors at the bank's back entrance, and was making his way through the vestibule when a skinny, hooded man ran through the interior set of double doors. "He pushed me and said, 'Get out of my way man'," Williams told The Edge in an interview.

Williams began to chase Brailen Weaver, 18, but a bank employee standing in the doorway Weaver had just run through, told Williams not to, pulled him inside the bank, then closed and locked the doors.

"Have you been robbed?" Williams asked. Yes, said the employee, who then asked Williams to please help. Someone had been shot. Williams was led to where Brian Switzer, 42, lie facedown and unconscious in a puddle of blood. Williams rolled Switzer face-up, and found the bullet wound. With the help of another bank employee, Williams began applying pressure to the wound to stop the bleeding. "We got a cloth from someplace," Williams said. "I don't know where it came from exactly. We might have taken it off of Brian. I don't remember."

Switzer was still breathing, Williams recalled. "And he had a pulse. I instructed [the bank employee] to keep direct pressure on the wound and apply digital pressure, which means you keep pressure on it for a bit, then release it and so on."

Williams said that it was after he and the bank employee had begun their bleeding protocols on Switzer, that he discovered the body of Breanna Edwards, 35, on the floor behind the customer counter. "I didn't even know she was there until [the bank employee] said something, I can't remember what. So I left him with Brian and went to look for her," Williams told The Edge.

"I looked over the counter and saw Breanna on the ground and I knew from her injury she was not going to survive, that she was already gone, and Brian wasn't, so I went back to help him," Williams said.

By this time, Williams said a police officer had arrived and told him and the bank employee that an ambulance was on its way. Williams was taken to one of the bank offices and asked to remain there rather than walk through the crime scene. The bank employee that had assisted with Switzer's wound was in the room with Williams. "He was really traumatized. He was extremely upset and emotional, and in shock and a state of panic, I think," Williams recalled.

Williams eventually left the office to talk with the first responders now attending to Switzer. "I wanted to see how he was doing," Williams said. "She said, it didn't look good, or something like that."

Speaking about his and the bank employee's efforts to slow Switzer's bleeding, Williams said in the interview, "He made it to the hospital, which is I guess some sort of an accomplishment. I can't tell you whether the bleeding had completely stopped because it was a mess."

Switzer died shortly after the ambulance took him to Saint Joseph Berea hospital.

Williams said when he saw Switzer, he flashed back to a time when, after being drafted by the Army in 1968, he was in Vietnam. "I reflected on my experiences, and acted accordingly," Williams said, adding that the moment was emotional for him. "You know, I was better for the first couple of days [after the shootings], but lately, it's been recurring. But you know, I can handle it. I have been through a lot of things."

Williams said that after returning from the war, he was diagnosed with multiple conditions, including PTSD. "I believe this incident is similar, but won't have the same impact, perhaps. But, it is reminiscent of something that is for me, you know, regretful that I couldn't do more."

Eventually, Williams said he was led out of the bank by a detective. "I think it was KSP [Kentucky State Police], but whoever it was, they were very professional and I told him what I just told you," he said.

Weaver has been federally charged with armed robbery, firing a weapon in a crime of violence, and causing death. Kentucky Attorney General Russell Coleman has said the state will pursue homicide charges against Weaver.

Multiple charities have been set up to support the survivors of the victims of this crime. Berea Strong will hold a fundraiser at the Madison County Fairgrounds on May 15 from 6pm to 10pm. It will include live music, a dinner, and a silent auction the proceeds of which will be donated to the families of Edwards and Switzer. For more information, visit Berea Strong's Facebook page.
