(CBS/AP) GREENVILLE, N.C. - A man armed with a "pistol-grip shotgun" and a bag filled with ammunition injured four people Friday outside a North Carolina law firm and a Wal-Mart before being subdued by police.
"He had enough [ammunition] to really do some significant damage," Greenville Police Chief Hassan Aden said.
The victims are all in operating rooms at local hospitals, Aden said. He didn't give specifics on their conditions or their names and ages.
Police say they are still trying to determine the shooter's identity and motive. He is in police custody at a local hospital, according to Aden.
The suspect was expected to survive as well as the four others he's accused of shooting, Aden said at a news conference.
The gunman's first target was seated in his car outside the Kellum Law Firm on Greenville's south side. The firm's main office in New Bern declined comment. Kellum has nine personal injury offices in the eastern part of the state.
The suspect crossed five lanes of traffic on a busy street after the Kellum shooting and injured the three others outside a Wal-Mart before he was caught, Aden said.
Officers confronted the man outside the store and caught up with him behind a nearby Toys "R" Us. He fired at them and they shot multiple rounds back, wounding the gunman, said Aden.
Police are still sifting through video footage of the scene.
Greenville is about 85 miles east of Raleigh.
