Four men were wounded -- at least one gravely -- in an apparent shoot-out Wednesday night that sprayed bullets into the street outside a James Island home, authorities said.

Charleston County sheriff's deputies raced to the area after gunfire erupted outside 1026 Seaside Lane at 8:42 p.m. One man was reportedly shot at least six times in the barrage of bullets, and his wounds are considered life-threatening, sheriff's Maj. John Clark said.

That man and three others were being treated at Medical University Hospital, Clark said. The Sheriff's Office did not release their names or ages, and the severity of the other victims' wounds could not be determined.

Clark said investigators still were trying to determine a motive for the violence and exactly how many shots were fired. "There were a lot of shots," he said.

Neighbors gathered on porches and along the sides of the dimly lit street, off Fort Johnson Road, as deputies taped off a large section of roadway to search for evidence.

At least 14 evidence markers could be seen on the road, and a half-dozen shell casings glinted in the lights of each passing car. Neighbors said they came outside when they heard gunfire, but all denied seeing what happened.

Clark said one of the victims could be a suspect in the shooting, and he did not rule out the possibility that other people could be involved as well. Deputies were looking for a green Ford Taurus or Mercury Sable that was reported to have been seen in the area, he said.

Deputies determined that one of the victims also was wanted on outstanding warrants by the Sheriff's Office, and investigators planned to arrest him if he was released from the hospital, Clark said. He said he did not know specifics about the charges.

The area has been the site of at least two other shootings in the past year, including one outside the same home.

In December, an 18-year-old man was shot twice in a drive-by shooting while visiting friends in the backyard of 1026 Seaside Lane, authorities said.

Clark said investigators still are looking into possible connections between the two incidents, but knew of no firm link at press time.

Anyone with information on the shooting can call Crime Stoppers at 554-1111.
