ROGERS COUNTY, Oklahoma - Rogers County deputies have three suspects in custody after a man was stabbed to death at a rodeo in Inola late Sunday night. The victim has been identified as 24-year-old Fabian Perez.

RCSO said they're also looking for a person of interest.

A major with the Sheriff's Office confirmed three people have been arrested in connection with the stabbing at the Riverbend Arena located west of Inola on 600 Road and 4160 Road. Sheriff Scott Walton said a fight broke out between two groups attending a rodeo and concert.

There was an ongoing feud between the two groups, he said.

The sheriff says at least a couple hundred people were here at Riverbend Arena for last night's rodeo when the fight broke out.

The Rogers County Sheriff's Office said the fight between the two groups of people ended with Perez being stabbed while he was on a horse in the staging area for rodeo participants. 

The three people: Margarito Escarino, Hipolito Pina and Richardo Escarino were arrested on complaints of homicide and assault.

When Rogers County officials arrived, Perez was already dead with a couple of stab wounds. Another person was flown to a hospital and RCSO said they are expected to survive the attack. That person's name has not been released. 

The sheriff's office called in other departments to help out and they spent hours interviewing people, asking them what they saw or heard.

Walton said this was an unusual situation for the county.

"We go back to how many killings we've had in Rogers County the last few years and we don't have them," Walton said.
