Motorcycle expo canceled Sunday after one dead, seven injured in shooting, stabbing

DENVER -- One person was killed and seven others were injured after a shooting and stabbing at the Colorado Motorcycle Expo on Saturday.

It started around 12:48 p.m. with a disturbance at the National Western Complex near the Denver Coliseum, the Denver Police Department said. Gunfire was exchanged, with at least one stabbing, police say.

There were eight victims, Denver Police Chief White said at a news conference Saturday night. Four people were shot, one was stabbed and three others suffered minor injuries during fistfights.  One of the victims who was shot later died at the hospital.

Nobody has been arrested, though some were visibly led away from the event in handcuffs to be questioned. White said that one person of interest is being interviewed.

White said two motorcycle clubs were possibly involved in the altercation, and no Denver police officers were involved.

Denver Health was placed on lockdown for nearly three hours after seven of the victims were transported for treatment. Denver Health said three victims are in critical condition and three are in stable condition.

Heavily armed police officers were on guard at every street corner near Denver Health for much of the afternoon. The lockdown was lifted at approximately 4:30 p.m.

More than 10,000 people were in attendance at the event. Though tensions were high, the motorcycle event continued through Saturday night, though many of the attendees were evacuated. The show closed at 5 p.m. and the event was canceled for Sunday.

Refunds will be issued to ticket holders, the City of Denver said. The event has taken place for more than 30 years and never had violence of this kind occur before, police said.

The Arena Cross event being held at the National Western Events Center night will go on as scheduled with shows at 7 p.m. Saturday and 2 p.m. Sunday. The Arena Cross has no relation to the Expo, according to the City of Denver.

Multiple ambulances and police officers were at the scene; police said that officers were able to respond quickly because of their presence already at the scene. Some were off-duty and some were working for the stock show at the time of the incident.
