Officials are investigating a possible link between weekend fights at three prisons and the arrest of a man accused of shooting, stabbing and then burning a man and three women in a southwest Oklahoma City house Nov. 9.
On Friday, prosecutors filed six first-degree murder counts against an David Allen Tyner, an American Indian. They accuse him of killing a Hispanic man he once worked for as a bodyguard, the three women and two unborn children.
The following day, a series of fights between American Indians and Hispanics broke out in three prisons across the state.
Oklahoma County Sheriff John Whetsel said he received information that Saturday prison fights in Granite, Hominy and Cushing were linked to the deaths. The fights sent six inmates to hospitals.
Whetsel said he had heard that Tyner was a member of a gang called the Indian Brotherhood, which may have been involved in the prison fights.
"That’s the indication we have,” Whetsel said Monday.
"We’ve got nothing that confirms that for us, but given the nature of the crime itself and the rumors regarding these other occurrences, we’ve maintained tight security and we’ve gone back and rechecked it.”
Tyner was a bodyguard for victim Casey Mark Barrientos, 32, who was in and out of prisons for several years for drug convictions, officials said. Barrientos also once was involved in a drive-by shooting.
