Ohio Changes Lethal Injection Approach COLUMBUS, OHIO (Associated Press) -
Ohio has become the first state to adopt a one-drug approach to lethal injections, a method used routinely on house pets but never tried on humans.

According to a filing Friday in U.S. District Court, the state has decided to switch from its current three-drug cocktail to a single injection of thiopental sodium, with a muscle injection available as a back up.

The state's decision comes two months after a death row inmate walked away from an unsuccessful execution when prison staff couldn't find a suitable vein.

The state has been looking for alternatives to the three-drug cocktail since a federal judge said it couldn't go forward with a second planned execution attempt of Romell Broom.

Subsequent executions also were put on hold. © Copyright 2012, Associated Press
