Kyle Eastridge and the Oklahoma State Bureau of Investigation endured a brief, uncomfortable marriage.
Eastridge, a former homicide detective with 25 years of experience, chafed under OSBI's secrecy and restrictions. He said he did not feel welcome.
"Agents didn't want me meddling in their cases, even though my efforts advanced their cases," he said. "That philosophy is outdated. To take sole possession of a murder case is absurd. It takes a lot of people to close a homicide case."
Typically, law officers make arrests when they have established probable cause. A district attorney then decides whether to file charges against the suspect.
Unpopular decisions could affect a district attorney's chances of re-election.
"There is no statutory requirement in Oklahoma for law enforcement to have approval of a district attorney to make an arrest, and it's that way on purpose," Eastridge said. "It's a checks and balances system. It's to prevent politicians from deciding when we have to make an arrest."
Sometimes, he said, investigators need to make arrests even if prosecutors are reluctant to file
"Let the DA decide to release a murder suspect that you have evidence on," he said. "That's not going to happen, I guarantee you."
Jessica Brown, OSBI spokeswoman, said Eastridge doesn't understand that the agency cannot afford to anger prosecutors.
"It reflects his lack of understanding of the OSBI and the difference between original jurisdiction and limited jurisdiction," she said. "The district attorneys determine if we get a case in their jurisdiction. We cannot be helpful if the DA doesn't want us there.
"We have to have a decent relationship. We can't ride roughshod over the system."
