The Circuit Court of Appeals in the U.S. denied Cuban inmate Juan Carlos Chávez' appeal to delay his execution for the crimes of kidnapping, rape and murder of minor Jimmy Ryce in 1995.

The denied request to delay his execution left Chávez with low chances to prevent his execution, planned for the night of Wednesday, Feb. 12 in Florida. The Court pointed out that Chávez was looking for a substitute lawyer, a request that was also denied by the Court.

According to CBS, Juan Carlos Chávez might face the death chamber after being found guilty in 1998 of the death of Jimmy Ryce, a 9-year-old boy who was kidnapped, raped and murdered by Chávez.

Juan Carlos Chávez plead guilty in November 1998, confessing that in September 1995, he kidnapped the 9-year-old boy after threatening him with a gun as he stepped off the school bus after classes. The man said he kept Jimmy locked against his will in a trailer, where he raped him and when the boy attempted to escape, he shot him to death. The case was described by the Supreme Court of Florida as brutal when it was revealed that the boy's body was dismembered and placed in pots before being covered in concrete.

The execution order was signed by Florida's governor, Rick Scott. Chávez, 46, will be the fourth inmate executed with Madazolam hydrochloride, a deadly cocktail that according to the convict's lawyers, violates the Constitution since it's described as a combination of chemicals that cause "cruel and unusual" reactions.

The new drug has been used in other cases such as the recent execution of Dennis McGuire in Ohio, who had a slow death.

Juan Carlos Chávez' execution is programmed for 6 p.m. local time, at the Florida State Prison in Starke.
