Arizona executes Donald Edward Beaty by lethal injection

(CBS/KPHO) FLORENCE, Ariz. - Arizona inmate Donald Edward Beaty, convicted of raping and killing a 13-year-old Tempe girl in 1984, has been executed with a drug that has never been used before in the state.

Beaty, 56, died by lethal injection at 7:38 p.m. Wednesday at the state prison in Florence after failing to win a flurry of appeals.

According to CBS affiliate KPHO, the state used a new execution drug as part of a three-drug method, replacing the controversial drug sodium thiopental with pentobarbital.

Beaty was on death row for two decades after being convicted of raping and murdering Christy Ann Fornoff.

She was making collections on her newspaper route with her mother at a Tempe apartment complex where Beaty was a custodian when he took her into his apartment, then raped and suffocated her.

Fornoff's family spoke briefly after the execution. They said they were relieved that Beaty said he was sorry to them.

"We just, as a family, are going to be peaceful about this, and we just want you to know that we feel peace right now," Christy's mother Carol Fornoff told the station.
