Ohio says it's dropping the two-drug combination used in the troubling 26-minute of an inmate a year ago during which the prisoner repeatedly gasped and snorted.

The state prisons agency also says it's adding a drug to the lethal injection system that it previously used from 1999 through 2011.

The Department of Rehabilitation and Correction said Thursday that the Feb. 11 execution of a condemned child killer is being delayed as the agency secures supplies of the new drug.

The state said in addition to delaying the execution of Ronald Phillips, set to die for the 1993 rape and killing of his girlfriend's 3-year-old daughter, other executions might also be delayed.

It's unclear where Ohio might get supplies of thiopental sodium, the anesthetic drug it's bringing back.
