Logan County Sheriff's Deputy David Wade was shot and killed Tuesday morning while serving an eviction notice at a home near Mulhall Rd., near I-35.
The suspect, Nathan Aaron LeForce, 45, of Logan County, was taken into custody at approximately 2 p.m. after an extensive manhunt.
Wade was taken to a hospital for treatment, but died from his injuries.
Devereaux, who took office as Logan County's sheriff January 1, said it is common for one deputy to handle evictions, but also said "it takes once incidence to change the way we do business".
Wade's Facebook page shows a beaming Wade standing with his son and wearing a T-shirt that says "My son is a Marine".
Kera Philippi said she had heard earlier in the day that Wade was still alive, but she did not know his condition.
"He gave his life serving his community, and I don't think you can have a bigger honor than that", Devereaux said, holding back tears.
Oklahoma City police say the suspect stole a vehicle and took off.
Vincent said LeForce was found in a nearby outbuilding, where he surrendered to authorities.
Devereaux said LeForce would now be interviewed to get his version of events.
