HORRIFYING images have emerged from inside the home where police say they found 16 children living in deplorable conditions.

Piles of trash and discarded toys can be seen strewn around the property in Hamden, rural Ohio.

Items including a high chair, tires, food and insect killer are visible at the dilapidated property which police say housed the 16 children.

A pile in the yard is filled with a plastic play table, a beach pail and two infant carriers.

The children had been confined to just one room – roughly 12 feet by 12 feet – over much of the past four years, authorities said Wednesday.

Investigators have described a home in wretched conditions with human waste all around.

The closest neighbors are separated by trees and thick brush, but the house is easily visible from the road.

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 pᴀssing by.

The home is currently the focus of a police investigation after the children’s parents and two grandparents were charged with felony child endangerment, a prosecutor said.

Some of the children discovered Tuesday were unable to speak and one — an 18-year-old who was developmentally disabled — could not even write her name, investigators said.

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

“It’s the type of thing that we’re not used to seeing here in America,” Ohio Attorney General Andy Wilson added.

Police said they were carrying out a search warrant in an unrelated investigation when they discovered the children.

They believe no one outside the family knew about the children, who weren’t enrolled in school.

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 ᴀssigned lawyers.

Wilson said they are identified as a grandpa, grandma, father, and mother of the children.
