(CBS/AP) LAS VEGAS - Authorities have identified the patron whoKenneth Brown.
He died in the casino after trying to subdue a man who shot two staff members.
Brown, 40, was fatally shot after wrestling the gunman to the ground early Monday at Drai's After Hours club inside Bally's hotel-casino, according to charging documents filed Tuesday.
Benjamin Frazier, a 41-year-old ex-convict with a history of alcohol-related arrests at Las Vegas Strip clubs, faces murder, attempted murder and weapons charges in the deadly dispute.
Witnesses told police that Frazier started shooting because he was upset he didn't get a refund of a $30 cover charge.
A club manager was wounded in the arm and a security guard was shot in the stomach before Brown tackled Frazier as he tried to leave the club with a gun in his hand, Clark County Sheriff Doug Gillespie said.
According to CBS affiliate KLAS, an arrest report says Brown died after Frazier shot him in the upper chest and neck.
The sheriff called Brown a hero.
"Security professionals and a heroic patron who lost his life prevented what could have been even more death and injury," he said.
Brown recently moved to Las Vegas from Los Angeles, his mother, Norma Sattiewhite, told the Las Vegas Review-Journal. He worked as a club promoter and stand-up comedian.
Police and a family member, attorney Bob Beckett, said Frazier was treated for serious head injuries he suffered when he was subdued and a family member says he remains hospitalized in a coma, according to the station.
The firearm Frazier used was reportedly a .38 caliber revolver.
Frazier was convicted in 1997 of felony assault with a deadly weapon in a plea deal stemming from a June 1996 incident at a Las Vegas club. His attorneys said he completed a sentence of two years' probation, performed community service and took impulse control classes.
Beckett said Frazier is his cousin and had been working at a car dealership in recent months.
Police said the club, which has a capacity of about 500 people, doesn't have metal detectors at the entrance.
