Members of two rival motorcycle clubs — one largely made up of police officers — are blaming each other for a fight Saturday that left one man dead and seven others shot or stabbed.

No arrests have been made, police said Sunday, and the seven injured at the Colorado Motorcycle Expo remain hospitalized.

Stephen Stubbs, an attorney for the Mongols Motorcycle Club, says members of the Iron Order Motorcycle Club taunted Mongols into an argument and then escalated the violence that led to the fatal shooting of a Mongols member.

Many of those in the Iron Order are police officers, military members and other law enforcement officers.

“The Iron Order are cowards,” Stubbs said Sunday. “The Iron Order started an argument. An Iron Order member threw the first punch. And when they were handily losing the fight they pulled out a gun and shot a Mongol. The only person who died here was shot by a member of the cop club.”

But John C. Whitfield, a lawyer for the Iron Order Motorcycle Club, said Sunday the shootout may have started when three members were jumped by members of one or more biker gangs.

Vince Bohm, who identified himself as a member of the Mongols Motorcycle Club, said an off-duty police officer fatally shot a Mongol.

Whitfield said a Colorado Department of Corrections officer fired a shot during the incident, but he didn’t know if that bullet hit any Mongols.

Stubbs, Bohm and Whitfield did not witness Saturday’s brawl at the 38th annual motorcycle expo, but relayed what they heard from numerous members of the two clubs.

A large number of the Mongols, a biker gang whose website advises that they are “the baddest motorcycle club known worldwide,” were at the expo. Members of other outlaw motorcycle gangs including the Bandidos and Hells Angels also were there.

Stubbs claims that the Iron Order likewise identifies itself as an outlaw motorcycle club, because it uses three patches to identify different ranks of members.

“They are known for picking fights and being jerks,” he said. “It was a fair fight until the Iron Order member pulled out a gun. For them to come out and play the victim when they picked the fight is outrageous. They are a bunch of cops who say the rules of society don’t apply to them.”

The U.S. Department of Justice classifies the Mongols as a highly organized criminal enterprise.

Members of the Mongols did not fire a single bullet during the confrontation, Stubbs said.

He said the incident began near the basement where several Mongols had booths set up to sell T-shirts, Stubbs said. Several Iron Order members were drinking beers and staring the Mongols down. A group of Mongols walked over and said, “What are you doing here? Get out of here,” Stubbs said.

One Iron Order member shoved a Mongol. A Mongol knocked a beer out of his hand. During a fight that broke out, another Iron Order member, who appeared to be drunk, pulled out a gun, waved it in the air, yelled profanities and threatened, “I’ll shoot you,” Stubbs said.

At that point, one of the Mongols charged the gun-toting man to tackle him and the Iron Order member shot him, Stubbs said. A melee broke out in which the Mongols had beaten their rivals, he said. The man who was armed stood up on the stairs and began waving his gun again. Another Mongol charged after him again and the Iron Order member fatally shot him, Stubbs said.

The Iron Order member who shot two men was handcuffed and taken to the police station to be questioned, he said.

“Even Mongols have a right to defend themselves,” Stubbs said.

The version Whitfield tells is much different.

Only about 15 members of the Iron Order were attending the event when three got separated from the group and were jumped by members of the Mongols, and possibly others, he said. “Once that happened, there was an opportunity to jump them, and they were sorely outnumbered,” Whitfield said.

Whitfield, who is flying to Denver Sunday to help handle the matter, said the fight started on a flight of stairs. “There were Mongols in front, and Mongols in back,” and they began harassing an African-American member of the Iron Order.

“One of the Mongols knocked a beer out of his hand and called him a racial slur,” Whitfield said.

Another member of the Mongols then confronted the corrections officer, and another Iron Order member, who was later taken into custody.

The Mongols shot first, Whitfield said. “It grazed one of our guys, and then hit another one. Then they stabbed one of our guys repeatedly and started beating up the other fellow.”

The corrections officer fired his gun “clearly in self defense,” Whitfield said.

Bohm, a former “patched” member of the Mongols, said he arrived at the show just after the shooting as a large group of Bandidos were streaming out of the Expo.

The primary combatants were members of the cop club and the Mongols, but it was an off-duty cop who fatally shot the Mongol, he said.

He said he is concerned that any investigation will not result in charges against a police officer, even though shooting a gun at a crowded show with kids is very dangerous.

“If a cop shoots him they’ll find some way to get him off,” Bohm said Sunday.

Detectives continue to interview witnesses Sunday, Raquel Lopez, Denver police spokeswoman said.

“As of right now there are no arrests,” Lopez said. “They are still trying to figure it out.”

Lopez said she does not know which gang the person who died Saturday is affiliated with.

And that isn’t a detail that Chief Robert White is going to release at this point, she said.

Detectives have not been able to question some of the key witnesses, including those who were shot or stabbed, because they are still undergoing treatment.

“There is a lot of information that is still not known,” Lopez said.

Lopez said she cannot comment on whether guns used in an exchange of gunfire have been obtained. That information is part of the investigation and will not be revealed, she said.

Denver police spokesman Sonny Jackson said the melee will be thoroughly investigated and when the review is complete, the case will be presented to District Attorney Mitch Morrissey for possible charges.

“We’re hearing different things about what happened,” Jackson said. Before the police department releases facts about what happened they will conduct an investigation including collecting evidence at the scene.

The Denver Coroner’s Office will release the identity of the dead man, she said.

Stubbs declined to name the dead man.

The injured were taken to Denver Health Medical Center, and the hospital was put on lockdown for a few hours Saturday afternoon.

The lockdown has since been lifted, and the hospital is in normal operations, though officers are still on the scene to prevent further trouble.

The seven people injured Saturday remained hospitalized Sunday. Three are listed in critical condition and four are listed in stable condition.

Denver officials canceled the expo’s Sunday session at the National Western Stock Show Complex.

On Sunday, the expo’s organizer posted a short message apologizing to vendors and patrons for the inconvenience.

Robert Lee comes to the event every year from his home in England to buy and sell motorcycles.

On Sunday, he was loading a pair of motorcycles he had sold into a trailer.

The shooting broke out near the spot where he was selling, but he had left his booth to get a bowl of chile, and didn’t witness the bloodshed.

When he returned to the booth, police had cordoned it off, and he was unable to sell anything else. The violence, “just killed business stone dead,” he said.

“We do get gang fights in England, but they try not to do it in public. It is just wrong to bring guns to an event like this,” he said.

Donald Haverland, who was showing motorcycles at the Expo with his wife, has come to the event for each of the past seven years.

During that time, there have been altercations between packs of bikers, but nothing as serious as Saturday’s deadly brawl.

“But I have noticed a level of antagonism increasing over the years,” he said.

When the couple first began coming to the show, Haverland said, he often saw several members of different motorcycle clubs talking to each other. Most of the bikers considered the event neutral territory.

But over the past two or three years, he noticed a change in attitude.

“Someone would walk up to somebody real fast like they were mad, and then stop about 10 feet away and stare at them, and there were groups bumping into others, he said.

“I haven’t wanted to come for the past five or six years because I could see an escalation,” Haverland said. He came this year because his wife, Rochelle Hayes-Haverland, insisted.

She said she heard about the brawl while she was attending the Tanner Gun Show, held at the Denver Mart, on East 58th Avenue. “I was shocked,” she said.
