SAN ANTONIO -- A San Antonio man who was sent to death row more than a decade ago will be put to death this May.

Juan Castillo is set to die by lethal injection on May 24 for the murder of 19-year-old Tommy Garcia.

In December of 2003, Castillo, his girlfriend, and a third person lured Garcia to a remote part of town with an intent to rob him. During the robbery, Castillo shot and killed Garcia.

Implicated in the killing, the girlfriend and third suspect negotiated agreements and testified against Castillo during his trial.

On the strength of testimonies and other evidence, the jury convicted Castillo of capital murder in 2005.

During Castillo’s punishment phase, the state presented substantial evidence of future dangerousness. According to court documents, witnesses testified that Castillo would beat the mother of his child and at one point he shot a man in a road rage incident. Witnesses also stated that Castillo would boast about having killed people and other crimes in the past.

The jury found the evidence of future dangerousness and mitigating circumstances. The judge then imposed the death penalty.

According to court documents, Castillo sought a federal writ of habeas corpus. The federal district court denied an evidentiary hearing, denied him habeas relief, and denied a Court of Appeals.

The U.S. Supreme Court has already refused to review Castillo’s case.
