Man rapes, murders 9-year-old

A man who admitted to raping and murdering a nine-year-old boy was executed Wednesday in Florida.

Juan Carlos Chavez, 46, who spent the past 15 years on death row, was declared dead of lethal injection after 8:00 pm (0100 GMT Thursday), said Florida prisons spokeswoman Misty Cash.

He was put to death two hours later than planned due to a last-ditch appeal that was ultimately rejected by the US Supreme Court.

Chavez admitted to kidnapping "Jimmy" Ryce at gunpoint as he got off the bus after school on September 11, 1995, and then raping him and beating him when the pre-pubescent boy tried to escape.

Ryce was missing for three months, before a massive police investigation turned up Chavez thanks to a tip from the owner of a horse farm where he worked and lived in rural Miami-Dade County.

The owner, Susan Scheinhaus, found Chavez with the child's school bag and with a weapon she had reported stolen.

Ryce's dismembered body was later found buried in cement in the garden of a neighboring farm, according to a court document.

In his last appeal to the Supreme Court, Chavez argued his constitutional rights to avoid "cruel and unusual punishment" would be violated if the state used the planned drug cocktail to put him to death.

Florida, like other US states, has experienced a shortage of the most commonly used lethal injection anesthetic, pentobarbital.

In response, it has been using a new cocktail since October: midazolam to render the inmate unconscious, followed by two additional drugs to paralyze and kill.

Midazolam was used in a controversial execution last month in Ohio, where witnesses said the inmate appeared to suffer.

Several of those sentenced to death have recently asked courts to stay their executions at least long enough to establish with certainty that these new products wouldn't force them to suffer.

Chavez's latest appeals focused on the appeal of another death row inmate in Florida, Paul Howell, who got the state supreme court to order serious scrutiny of the new injection protocol before his scheduled February 26 execution.

In his legal filing, Chavez demanded to be "treated equally by the courts," saying he would "suffer irreparable injury" if his execution went ahead as scheduled.

But the US Supreme Court denied his final appeal without explanation, giving the green light to execute Chavez.

His execution marked the eighth so far this year in the United States and the second in Florida, according to the Death Penalty Information Center.
