Ohio has executed a convicted criminal using a new two-drug system that was never tested in the U.S.
Ohio is the first state in the U.S. to use a new two-drug procedure in executions. 53-year old Dennis McGuire, convicted of raping and killing a pregnant woman in 1989, was executed on Thursday at the Ohio state prison.

He was pronounced dead at around 10:53 a.m. ET, the Ohio Department of Rehabilitation and Correction said.
The new method, developed due to the limited supply of pentobarbital, uses a mixture of midazolam, a sedative, and hydromorphone - a pain killer. Pentobarbital, a drug that can cause death through respiratory arrest, has been limited due to objections made by the manufacturers themselves.
Ohio ran out of pentobarbital in September last year, forcing the state to find alternative drug solutions.
The convicted McGuire previously made an appeal to the U.S. Supreme Court, asking for a stay of execution, because the drug was never tested in the U.S. and could cause him severe pain. The court has denied his request on Wednesday.
McGuire was found guilty in 1994 of raping and killing Joy Stewart. Her body was found by hikers in the woods. According to prosecutors, Stewart was stabbed twice in the neck and bled to death.
She was seven months pregnant.
