In the 18 years since 9-year-old Jimmy Ryce's rape and murder, his parents tried to alleviate the pain of their family's tragedy by working for society's good.

They pushed for laws regarding confinement of sexual predators and worked to improve police procedures in missing child cases.

But Don Ryce says he will finally feel some measure of justice. Barring a last-minute stay, Jimmy's killer Juan Carlos Chavez is scheduled to die Wednesday by lethal injection at Florida State Prison in Starke.

Chavez abducted Jimmy at gunpoint after the boy got off a school bus on Sept. 11, 1995, in rural southwestern Miami-Dade County. Trial testimony showed Chavez raped the boy and then shot him when he tried to escape, dismembering his body and putting the parts in concrete-covered planters.
