There is a possible fourth victim who could not be located, according to Denver police spokesman Sgt. Steve Warneke.
The Denver Police Department's official Twitter account provided multiple updates on the stabbing. At 9:55 p.m., DPD responded to a large fight at Lot F of Sports Authority Field, near Dick Connor and Federal Boulevard. Three male victims with stabbing wounds were located. Two are in stable condition; one is critical.
Three suspects are in custody at this time, Warneke said, and Denver police do not believe there are any suspects at large. There are a great deal of witnesses who are cooperating to provide more details.
"Detectives will be interviewing people throughout the night, trying to sort out who did what," Warneke said.
There was no word as to what prompted the altercation. Police likely will provide more information Friday morning after the interviews are conducted.
Officials from the stadium released the following statement Thursday night:
"Stadium Management Company is aware of an incident that occurred in a parking lot adjacent to Sports Authority Field at Mile High. We are currently working with authorities to gather more information."
