“Most of our livestock was kept in better conditions than the children,” said Vinton County Sheriff Ryan Cain. “Just a disgusting scene.”

The children’s parents and two grandparents were charged with felony child endangerment, a prosecutor said.

Authorities found the children while carrying out a search warrant in an unrelated investigation, Ohio Attorney General Andy Wilson said Wednesday at a news conference.

Officials said it seemed as if no one outside the family knew about the children, who weren’t enrolled in school.

“We didn’t know there were going to be 16 kids there,” said Wilson, who was nearly at a loss for words in describing what officials found in the tiny village of Hamden that sits in one of Ohio’s poorest counties.

“It’s the type of thing that we’re not used to seeing here in America,” he said.

The sheriff said it appears the children spent most of their time in a room that was roughly 12 feet by 12 feet. He didn’t disclose how the kids were kept inside the home, but said authorities didn’t find any cages in the house.

The children ranged in age from 1 1/2 years to 18 years old and included both boys and girls, officials said. Seven were transported to hospitals in Columbus and two were flown by helicopter. One was in critical condition on Tuesday while some of the others were admitted for care, Wilson said.

“They looked like almost feral animals,” Wilson said. “It was terrible.”

The children were in temporary custody of the Ohio Department of Jobs and Family Services.

Vinton County prosecuting attorney William Archer said the four adults were charged with second-degree felony child endangering because it involves “serious physical harm.”

Gary Siders Jr., Gary Siders Sr., Christina Siders and Elizabeth Siders appeared in court Wednesday where a judge entered not guilty pleas on their behalf and set bond at $300,000 for each. They have not yet been assigned lawyers.

Steve Irwin, a spokesperson for the attorney general’s office, would not say whether all of the children are siblings or how they were related.

The house where the children were found sits on a road tucked away alongside a steep railroad embankment, where tracks carry rumbling trains through Hamden. The closest neighbors are separated by trees and thick brush, but the house is easily visible from the road.

An open door revealed bits of trash inside while a wooden deck and the backyard were filled with discarded tires, a high chair and other debris.

Investigators said members of the family had moved around southern Ohio over the past two decades and that it looks like they avoided setting up medical and government records.

“These folks were pretty good at hiding these kids,” Wilson said.

Investigators were reviewing whether the family was reported to any children’s services agencies in the past.

Neighbor Joseph Stewart, 60, said he saw “no kids at all” since the family moved in three houses down and that he could clearly see the house and yard when passing by.

“It’s a sad situation,” he said. Stewart has lived on the street for six years and called it “a quiet neighborhood.”

On Wednesday, the home’s doors and windows stood open to the sweltering heat. A tangle of discarded children’s items — two busted bicycles, a plastic play table, a beach pail and two infant carriers — stood in a pile in the yard.

Hamden has a population of less than 1,000 people and is about 60 miles southeast of Columbus.

The discovery of the children is reminiscent of past horrific cases of family abuse.

In 2019, David and Louise Turpin pleaded guilty to torture and years of abuse that included shackling some of their 13 children at their home in California, starving them and providing only a minimal education.

They were sentenced to life in prison with the possibility of parole after 25 years. The couple were arrested in 2018 after their 17-year-old daughter escaped from the home and called 911.

The children weren’t enrolled in school, the family moved around over the past two decades, and neighbors said they’d never spotted the kids. The children remained mostly confined to a small room in the house, investigators said, under deplorable conditions.

“Right under our noses and nobody was able to help them sooner,” said Emily Collins, 27, owner of VC Farm & Floral in nearby McArthur. “It’s just crazy that all the wonderful things going on in our little Hallmark town and this is what puts us on the radar. It’s really sad,” said the mother of three, who was compelled to decorate the sidewalk with bright flowers and stars drawn in chalk to cheer herself up.

Authorities said they had gone to the home Tuesday on an unrelated investigation and discovered the children — ages 1 1/2 to 18 years old — some of whom were unable to speak.

Seven were taken to hospitals, including one who was in critical condition, investigators said. Their current conditions weren’t immediately known Thursday. Child welfare officials have temporary custody of the children.

A man who lives three houses down from the Siders family said he had seen “no kids at all” there.

“It’s a sad situation,” said Joseph Stewart, 60, who has lived in the “quiet neighborhood” for six years.

Four people who are the children’s parents and grandparents were arrested on child endangerment charges. Gary Siders Jr., 36, Gary Siders, 73, Elizabeth Siders, 33, and Christina Siders, 67, pleaded not guilty to child endangerment. Bond was set at $300,000 each.

An attorney for the elder Siders said he is presumed innocent.

“We ask that the community at large, as well as anyone who might have an interest in this case, to take a deep breath, step back, and let the case play out and the facts play out,” Dorian Baum told The Associated Press.

Attorneys for Siders Jr. and Christina Siders declined to comment. Messages seeking comment from Elizabeth Siders’ lawyer were not immediately returned.

Authorities wouldn’t publicly share the nature of the other investigation that led them to the house Tuesday. However, court records show a warrant was issued for Siders Jr. that day on misdemeanor indecent exposure charges related to alleged incidents on four days in May. He has pleaded not guilty.

On Thursday, windows and doors at the formerly wide-open home, about 60 miles (97 kilometers) southeast of Columbus, had been boarded up. Police tape and piles of refuse remained.

The previous day, a door was ajar and heaps of trash and children’s toys were visible inside. A wood deck and the backyard were filled with discarded tires, a high chair and other debris.

The house sits on a road tucked alongside a steep railroad embankment, where tracks carry rumbling trains to a rail yard in the village of fewer than 1,000 residents. The closest neighbors are separated by trees and thick brush, but the house is easily visible from the road.

Investigators said members of the family had moved around southern Ohio over the past two decades and that it looks like they avoided creating a medical or governmental paper trail. The Vinton County Local School District, the only district in the area, said it has no records indicating that any of the children were ever enrolled.

“These folks were pretty good at hiding these kids,” Ohio Attorney General Andy Wilson said Wednesday.

The children’s absence from school, and the apparent lack of regular visits with medical professionals, likely contributed to keeping the dire situation unknown, said Jacqueline Yahn, an associate professor at Ohio University.

“When kids are isolated or not participating, you don’t have someone who’s trained to know the clues,” said Yahn, who specializes in rural education and poverty. “A well-check is called that for a reason: They’re checking for well-being and development.”

Investigators were reviewing whether the family was reported to any children’s services agencies in the past.

The children spent most of their time in a room that was roughly 12 feet by 12 feet (3.5 meters by 3.5 meters), according to investigators, who noted that human waste was all around.

“They looked like almost feral animals. It was terrible,” Wilson said.
