Tina Curl has just one thing on her mind: Lethal injection.

The upstate New York mother is trying to raise $4,000 for a trip to South Dakota, where killer Donald Moeller is set for execution in the 1990 rape and murder of Curl's 9-year-old daughter.

"I've just got to see him die," Curl told the Daily News inside her mobile home in Lake Luzerne, N.Y. "I've got to see him pay for what he did to my baby.

Donald Moeller was convicted and sentenced to death for raping, stabbing and murdering young Becky in Lincoln County, South Dakota, back in 1990. Curl - who has since moved to Lake Luzerne, N.Y., with her husband, Dave, after Becky's murder - described her daughter as a "good-hearted" girl who loved her cats, and always made sure she gave everyone a Christmas present, no matter how small it was.

Becky went out to buy 50 cents worth of candy, and never returned to her South Dakota home. Curl remains haunted by that choice, and by her decision to let Becky go out by herself. Moeller abducted the little girl from a convenience store, and her body was discovered a day later.

"I live with that every day," Curl said Wednesday. "She left home just after 5 o'clock that day. The next time I see her, she was lying in a casket."

The innocent child was raped and stabbed, with Moeller slitting the girl's throat before dumping her mutilated body into a ditch.

Curl and her husband David had moved west with the little girl because they felt it was safer in South Dakota than living in New York.

Now, 22 years after killing O'Connell, Moeller will be executed on or around Oct. 24 in Sioux Falls - and Curl wants to be there.

She and her husband live on disability. Curl said she cannot fly because she has a heart condition.

"Nothing will bring her back," Curl, 50, said of Becky. But, "it's important [to see the execution] because he watched my daughter take her last breath. I want to see him take his last breath."

"She was all I had, she was something that I thought no one would take away from me," said Curl. "I finally had something that was all mine, and he took that away from me."

As of Wednesday, Curl said she and her husband had only managed to raise about $890 dollars through the fund they set up at a local credit union. She thinks people are hesitant to donate toward her cause because they disagree with capital punishment.

"They are all treating me like I am wrong," she said. "I don't care what they think. I believe in an eye for an eye."

Curl said she is considering sending Moeller a letter to let him know she plans to be present during his death.

"He watched my daughter take her last breath," said Curl, who returned to her childhood home in the southern Adirondacks after the slaying. "I want to watch him take his last breath."

Curl has since developed a crippling drinking problem, has her health has declined significantly in the years after her daughter's vicious death. She's suffered a heart attack and battles a vascular disease in her legs.

Her husband, 60-year-old David Curl, was laid off last month from his job at Jiffy Lube - leaving the family with no cash to fund the trip to Sioux Falls, S.D., for Moeller's last stand.

The couple is currently living off a monthly $720 disability check.

The lethal injection will occur between Oct. 28 and Nov. 3. Prison officials have yet to determine the exact date and time.

 "I don't like to ask people for anything," she said. "But at this point, I'm ready to beg, borrow and steal.

Moeller lived down the street from the Curls, and Tina Curl recalls seeing him once at a local yard sale.

The remorseless murderer was initially convicted in 1992, but was retried - and found guilty a second time - after an appeals court overturned the verdict.

After Moeller's 1997 murder conviction, his death penalty case dragged on for years in federal court.

But earlier this month, the convicted killer told a federal judge that he wanted the execution to go forward - 22 years after the killing.

"Mr. Moeller specifically told me that he accepts the execution as the consequences of his actions," his lawyer said at a July hearing.

Given the chance to speak, Moeller declined to say anything about the killing or his decision. The lethal injection will come inside the South Dakota State Penitentiary in Sioux City.

The state has executed just two men in the last 65 years: A 1947 electrocution and a 2007 lethal injection. Moeller, now balding with a long grey beard, had requested an Aug. 6 execution.

The still-mourning mother said the 60-year-old Moeller has never shown any remorse for the killing, and often smirked at her from the defense table during his murder trial.

She plans to return the favor at his execution. According to Curl, most inmates killed by lethal injection utter a final snort before the drugs kick in for good.

"They have no idea, but I already plan on cheering when he makes that snorting sound," she said.

"It's not going to bring my daughter back," Curl acknowledged. "But it's something I'm doing for me and Beck. Just knowing he is not going to be breathing anymore will bring a sense of relief."

The Curls' donation fund is through the Hudson River Community Credit Union at 1-800-824-0700.
