Ohio is struggling to find medical professionals willing to advise the state on the best way to put condemned inmates to death.

Attorney General Richard Cordray says in a court filing that ethical and professional considerations are deterring doctors and others from offering advice about lethal injection.

Executions are on hold in Ohio while the state develops new injection policies following a Sept. 15 execution that was stopped because the inmate had no usable veins.

Cordray's concerns came in a filing in U.S. District Court Friday.

He says his office has reached out to judges, police and lawmakers for help trying to find medical professionals willing to talk to the state.

He also says five lawmakers he didn't identify have agreed to try to find medical staff to help.
