While one woman has come forward with claims that her late father is a ruthless serial killer who killed dozens, her older sister claims it’s not true and has vowed to restore her father’s name.

Lucy Study argued their father, Donald Dean Studi, was a serial killer who forced her and her siblings to dump the bodies of the women he killed down a 100-foot well on their Iowa farmland decades ago.

However, her older sister, Susan Studi, rejected these claims and said that their father was strict but definitely not a murderer.

“My father was not the man she makes him out to be,” Susan Study said Newsweek. “He was strict, but he was a father who protected his children… Strict parents don’t just turn into serial killers.”

Donald Studi, who died in March 2013 at the age of 75, is accused by his daughter Lucy of killing between 50 and 70 women and at least two men – one in his 40s and the other in his 20s. Lucy said she had tried for years tell people, but no one listened.

Donald Dean Studi, who died in March 2013 aged 75, is accused by his daughter Lucy of murdering up to 70 women, but his other daughter Susan says the allegations are simply not true.

After 45 years, police are investigating allegations that an Iowa farmer killed up to 70 women after his daughter told authorities, “I know where the bodies are buried.”

The Fremont County Sheriff’s Office confirmed that cadaver dogs alerted at least four locations on the property last week, with the latter receiving several “hits.” The dog handler and the sheriff said they believe the remains are human because dogs are trained to ignore animal bones.

However, Lucy’s older sister Susan believes the cadaver dogs that searched the property last weekend were fooled by the remains of Donald Studi’s stillborn sister, who was buried in a shoebox on the property, as well as the remains of a golden retriever.

While Lucy told authorities their father forced the siblings to use a wheelbarrow in the warm season and sleds in the winter to transport corpses across farmland in Thurman, Iowa, her sister denied it.

Susan told Newsweek that she first heard about the burial of bodies on the property when she spoke with Lucy about a year ago.

“I’m two years older than Lucy. I think I would have known if my father had killed, she said. “I would know if my father was a serial killer. He wasn’t, and I want to restore my father’s name.”

Susan added that the only time she remembers her father becoming violent was when a neighbor ran over their dog – which led to Donald Studi getting into a fight with the man.

Her sister, Lucy, has repeatedly offered to take a lie detector test to back up her claims, according to Newsweek.

The third sister in the sibling group could not be contacted. Their brother committed suicide when he was 39 years old.

Four siblings, according to Lucy followed their father’s order when he told them to “go to the mountains” because they were terrified they “wouldn’t come back,” according to his daughter.

Lucy said her father was “usually drunk” and liked to kill women by smashing or kicking women in the trailer’s head.

Both of his wives predeceased him, police records show that one died after strangling herself with an electrical cord and the other shot herself.

Investigators believe his daughter’s claims are true and, if true, would make Studie one of the most prolific serial killers in American history.

Law enforcement authorities suspect he lured women believed to be sex workers from Omaha, Nebraska, to his five acres of land before killing them.

Lucy claims the women all had dark hair, white hair and most were in their 20s and 30s, except for a 15-year-old runaway and two men.

They were all buried clothed and bejeweled, and Lucy claimed her father kept the gold teeth as trophies.

However, Lucy's older sister Susan believes the cadaver dogs were fooled by the remains of Donald Studi's stillborn sister, who were buried on the property, and the remains of a pet

Lucy told Newsweek: “He just told us we had to go to the well and I knew what that meant.

“Every time I went to the well or to the mountains, I didn’t think I was going down. I thought he was going to kill me because I wouldn’t keep my mouth shut.

“I have no feelings for my father. Nothing at all. I wanted justice when my father was alive and he was gone. I just want some closure and a proper burial for the families.”

Studi reportedly forced his children to pour dirt and chemical lye on their bodies after throwing them down a well.

On Tuesday, Fremont County Sheriff Kevin Eistrup confirmed the investigation, saying “I believe her 100 percent that there are bodies there” and saying that if they do excavate the scene, it will be a “major mission.”

He added that the cost of drilling a well would be about $25,000 and a full excavation would cost more than $300,000.

The property on Green Hollow Road is not an official crime scene because officers have not yet recovered the remains.

Studi, who had ‘love’ and ‘hate’ tattoos on his knuckles, is believed to have a criminal history but is known to have used several aliases.

He spent time in prison in Missouri in the 1950s for petty theft, in Omaha in 1989 for driving under the influence of alcohol – as the cops confirmed, they rarely went to the trailer where he lived because they treated him ” cautiously.”

She added: “All I want is to dig these places up, close them to people and give these women a proper burial. My father was a criminal and a murderer all his life.”

It is not yet clear whether her siblings cooperated with authorities, and her brother Gary took his own life at the age of 39.

Lucy claims she told her stories to several people over the years in an attempt to do something about it, but “no one listened.”
