A proposed lethal-injection protocol in Nebraska has been submitted to Attorney General Jon Bruning for approval.

Last week, the state Department of Correctional Services signed off on the three-drug cocktail and the process of administering it to death-row inmates.

The department devised the proposed protocol and did not make any changes to the proposal after some raised concerns about it, including that it doesn't clearly specify how workers should be trained to administer the drugs.

If Bruning approves the proposal, it will go to Governor Dave Heineman for final approval.

Nebraska has been without a means of carrying out the death penalty since early last year, when the state Supreme Court deemed the electric chair cruel and unusual punishment.
