"You could hear him firing the whole time I was on the phone," she said. "The operator kept saying it sounded like fireworks. I said, 'No, no, no, no. Somebody's being shot.'"

John Bower added, "My wife kept telling her, 'They're shooting someone in our yard.' "

John and Anne Bower had just finished watching "CSI: Miami" and turned to the local news when they heard strange sounds coming from outside.

"We heard a couple of pops," Anne Bower said. "I thought it was a backfire. John said, 'No.' "

The couple went out to their sunroom that looks out over Kane'ohe Bay Drive and saw a surreal scene just 25 feet away in between two street lights.

The scene was dark but amid the lights of passing cars and the muzzle flash of the shooter's gun, the Bowers saw a man wearing only shorts lying face down on the street.

Another man, dressed all in black, was standing about 10 feet to 15 feet away, firing what appeared to be dozens of rounds into the man's back, John Bower said.

"It wasn't a handgun. It wasn't a rifle," John Bower said. "He was holding it in one hand and it sounded like a machine gun. It was maybe 40 shots, 50 shots — lots."

Anne Bower called 911 and — while still on the phone — continued to hear "dozens and dozens of shots. You couldn't shoot a gun that fast. It was over and over and over. The whole time I was talking to 911 I said: 'No, no, not fireworks.' "

Anne Bower estimated that the shooting lasted about five minutes.

"It seemed longer," she said. "It's hard to tell time. It seemed like it went on and on and on."

At one point, the gunman started walking away toward a car parked about 50 feet away. But the victim started moving, John Bower said, "So he came back and shot him some more."

"John said, 'He's still moving,' " Anne said. "The guy walked to the car but he went back and shot him some more times. Very calmly."

The driver of the car then rolled up, got out and started speaking to the shooter, Anne said.

"There was a brief moment when they said something to each other," she said.
