The suspect in the shooting rampage at a Tuscaloosa, Ala., bar that wounded 17 people has turned himself in, the Tuscaloosa News reports.

The newspaper says one of the wounded is hospitalized in critical condition, another in serious condition and three are listed in fair condition.

Update at 6:50 p.m. ET: The suspected gunman, identified as 44-year-old Nathan Van Wilkins, has been charged with 18 counts of attempted murder and other firearms offenses, the Tuscaloosa News reports. He is being held on $2 million bail.

Police also believe that after the shooting spree, Wilkins set fire to three trucks and a gas well rig belonging to his former employer, Capstone Oil Field Services.

The paper writes that a Facebook page for a Nathan Wilkins of Northport, Ala., who claims to work at Capstone Oil, included photos of a man with tattoos on his arms, posing with an assault rifle, standing in front of a Confederate flag and making an obscene gesture. The page has been taken down.

The Associated Press says authorities believe that he targeted someone at the bar and that it was connected to an earlier shooting at a home. But a motive was still unclear. One possibility is that the shootings resulted from a dispute between motorcycle gangs.

Police have not released the names of the wounded. The University of Alabama confirmed that Kelvin Sigler, a former defensive back and now a member of the football team's support staff, was treated for a bullet wound to the forearm and released.

Update at 1:43 p.m. ET: Police are looking into whether the rampage was connected to a shooting about 45 minutes earlier at a home a few miles away, the Associated Press reports. Tuscaloosa Police Chief Steve Anderson says two people who lived there were involved in that shooting, and one was wounded, the AP reports.

Update at 1:32 p.m. ET: A suspect wanted for an early morning shooting rampage at the Copper Top bar in downtown Tuscaloosa has turned himself in, The Tuscaloosa News reports.

The newspaper says the man, who identified himself as Nathan Harris, walked into a FedEx store in Jasper, Ala., and told the owner he wanted to give himself up.

"He walked in and said, 'Yeah that's me.' I guess when you do something that high-profile, you expect everyone to know who you are," Ken Barfield, owner of the FedEx, tells the newspaper.

The suspect's image was widely distributed on surveillance video released by police.

Barfield says there was no indication why the man chose the FedEx office to give himself up.

"I said, 'I guess I need to call the police.' I didn't want to agitate him further," Barfield tells the newspaper. "He was sweating profusely," he said "I offered him a Powerade and told him not to walk toward the police when they showed up. I told him to put his hands in the air."

Police arrived about eight minutes later.

Update at 9:14 a.m. ET: Tuscaloosa Police Chief Steve Anderson tells the Associated Press that the gunman fired first through a window of the Copper Top bar, then shot at people outside as they fled. He says the gunman never went inside during the assault.

Hospital spokesman Brad Fisher says 17 people are being treated at DCH Regional Medical Center. Two of the victims are receiving critical care, Fisher says.

The bar is near a downtown square in an area that's home to several nightspots and is popular with students from the University of Alabama.

Original post: The Tuscaloosa News reports that the gunman began firing into the Cooper Top bar in the city's Temerson square area.

Around 80 people were inside drinking and playing pool at the time, the newspaper says.

The newspaper quotes an unidentified source close to the investigation as saying events elsewhere in downtown Tuscaloosa earlier may have led to the shooting, but does not elaborate.

Video released by police show a man from the back as he walks down a sidewalk with what appears to be a gun in one hand. Police describe him as the suspect in the shootings.
