A 24-year-old Lincolnville man with alleged gang ties was carrying a stolen pistol when a barrage of gunfire in Myrtle Beach killed three people and wounded him during a motorcycling festival on Memorial Day weekend, according to court documents.

Keith Alextrus Williams of East Railroad Avenue was arrested Thursday on a count of possessing a stolen pistol.

But Capt. David Knipes of the Myrtle Beach Police Department said Friday that the firearm had not been used during the violent outburst near the Bermuda Sands Motel.

Williams' was the second weapons-related arrest of a Lincolnville man in connection with the shooting, but no one has been implicated in the slayings. Another faces a count of disorderly conduct.

It came a day after family members and Myrtle Beach authorities pleaded for the public's help in solving the crimes during a news conference in Summerville.

With four bullet wounds, Williams had been in critical condition at a Myrtle Beach hospital. But he was booked into Horry County's jail around 1 p.m. Thursday, where he remained the next morning in lieu of $10,000 bail.

He was one of several people from the Summerville area who was shot during the confrontation in which police investigators had suspected gang activity. Jamie Alexander Williams, 28, Devonte Herman Dantzler, 21, and Sandy Geddis Barnwell, 22, were killed.

Locally, Charleston County sheriff's deputies knew Keith Williams to have ties with the "Town of Lincolnville," or TOL, gang. But Myrtle Beach authorities said this week that they had not been able to establish a gang link in the shootings.

In December 2012, Williams was arrested on an attempted murder charge after deputies said he shot 14 times into the Game Room, a Ladson nightclub. He wasn't accused of hitting anyone, but someone fired back, and a bullet struck Williams' friend, Nathaniel Nelson Green, in the hip.

Green, a rap singer from Lincolnville, was with Williams again May 24, when the gunshots rang out near the Myrtle Beach motel at 104 N. Ocean Blvd. Though he was an intended target, according to police documents, Green avoided injury. But the police said they also found a gun on Green, and he was arrested on a count of being a felon in possession of a firearm.

Molefi Atone Johnson, 21, another music performer from Lincolnville, also faces a count of disorderly conduct.

Williams had his stolen pistol, a .40-caliber Springfield XD, with him when he was shot, but he then put it in the trunk of his car, the affidavits stated. Investigators later found it there, the documents added.

But Knipes, the police captain, said Williams had never fired the gun during the fight.

The shooting came during a neighboring town's Atlantic Beach Bikefest, which has come under scrutiny since the weekend that included gun violence elsewhere in Myrtle Beach.

Because of the shootings, Gov. Nikki Haley called for an end to the motorcycling celebration, which annually draws tens of thousands of people to the Grand Strand.

Area police agencies have formed task forces in an attempt to stem the violence, and Atlantic Beach's mayor has said that the town will not do away with the bikefest.

But with the slayings still unsolved, investigators turned to the Summerville area for help earlier this week. After dozens of interviews, they have reached an impasse in the probe, but Myrtle Beach police officials said they think Summerville-area residents know something about the shootings and just aren't talking.
