Hearing gunfire in his Grand Prairie neighborhood, Lee Campbell shrugged it off Thursday night and continued playing his PlayStation.

When the scattered shots turned into a full-blown shootout that left four men wounded, the 61-year-old Chicago native and Vietnam veteran hit the deck — but still played on.

"First three shots I heard, I just ignored it and kept playing my game," he said. "When they started firing back at them, that's when I got on the floor, but I kept playing my game."

The shooting began about 8:30 p.m. when two men in a vehicle exchanged fire with two others standing in a yard in the 300 block of Dawson Circle, police said.

The vehicle came to a stop near Conover Drive, police said, and all four men were taken to hospitals with gunshot wounds.

A day later, blood still stained the streets. A blue surgical glove and garbage littered the lawn where the men were shot.

Police were working to determine what triggered the shooting across from Campbell's home, but he feels certain drugs were involved.

"Late at night around here, there's a lot of drug trafficking," he said. "If you let them, they'll take over the neighborhood."

Campbell moved into the house two months ago, and it's the first shooting he's seen here. But the former Marine has witnessed bloodshed before, and not just overseas.

"I grew up in Chicago, so I saw this all the time," he said nonchalantly. "I wasn't about to get up and get all mad for nothing just because some folks are out here shooting at each other."
