Lawyers try to spare Virginia inmate’s life as execution nears

Attorneys for Alfredo Prieto, a convicted serial killer in Virginia, are pushing to spare his life as his scheduled execution draws near.

The state had been planning to execute him at 9 p.m. Thursday at the Greensville Correctional Center, but it was unclear whether that will take place.

Prieto, 49, a native of El Salvador, was on death row in California for raping and murdering a 15-year-old girl when DNA evidence linked him to the rape and murder of Rachael Raver and the slaying of her boyfriend, Warren Fulton III. Authorities have linked Prieto to several other killings in California and Virginia, but he was not prosecuted for those because he had already been sentenced to death.

A federal judge in Alexandria approved an order Wednesday temporarily blocking Prieto's execution and called for a hearing after his attorneys raised concerns about one of the lethal injection drugs that the state intends to use.

But the hearing was canceled after the case was transferred to a new judge in Richmond. As of late Wednesday, no new hearing had been set on the matter.

His attorneys asked the court to delay the execution until Virginia officials disclose more information about the supply of pentobarbital they received from Texas, saying they're concerned about the quality of the drugs and whether they would cause him "gratuitous and unnecessary pain."

Virginia obtained pentobarbital from Texas to replace its supply of another sedative, midazolam, which expired Wednesday.

Prieto's lawyers requested the name of the supplier, tests confirming the drug's sterility and potency and documents showing that the drug was properly handled. Texas allows prison officials to shield where they get execution drugs, and Virginia officials have not provided that information.

Attorney General Mark Herring's office urged the judge to dismiss Prieto's case, noting that Texas has used the same drugs without any problems in 24 executions over the past two years and arguing that further delaying his execution and allowing him to "fully indulge his speculations" could prolong the case past the new supply's expiration date.

"Granting injunctive relief in these proceedings, then, may very well negate the commonwealth's ability to execute this serial murderer-rapist," Herring's office said.

The U.S. Supreme Court is also weighing Prieto's last-minute attempts to block the execution on the grounds that he's intellectually disabled.

Prieto's attorneys urged the high court Tuesday to delay his execution so he can continue to fight his death sentence in California, saying he would likely be deemed a person with an intellectual disability if granted the opportunity to pursue his appeal.

"There is a substantial likelihood that he's intellectually disabled, but he's never had a fair and reliable hearing to prove it," wrote Hilary Potashner, a federal public defender based in Los Angeles. "Without a stay, it is likely that the commonwealth of Virginia will execute an intellectually disabled man."
