A 26-year-old El Reno man was arrested on a complaint of manslaughter in connection with the death of Matthew Ryan Little Elk, 28.
Police said Dylan Elledge was taken into custody Nov. 9 after police received information that connected him to the death.
Little Elk was found unresponsive at 2630 Stone Glen Drive the night of Oct. 28. He was taken to Mercy Hospital where he was pronounced dead.
The state medical examiner, police said, ruled the cause of death was the result of blunt force trauma to the head.
Police said several witnesses inside the house refused to cooperate, but later information was received that led them to Elledge and the arrest. Police believe the men were involved in an earlier altercation that resulted in the fatal injury to Little Elk.
Elledge is being held in the municipal jail with bail set at $26,000.
Police plan to present information to the district attorney for consideration of formal charges.
