TOLEDO, Ohio -- Residents in a Springfield Township neighborhood had no idea one of their neighbors was living in squalor until emergency vehicles lit up their typically quiet street, the Toledo Blade reported.

The smell of human excrement reached the sidewalk as emergency responders worked to remove a 550-pound elderly woman from her living room chair Thursday evening. Barbara Foster, 75, had been sitting in the same place since July 2016 — long enough for her body to weaken and her skin to mold to the chair's shape, according to a Lucas County Sheriff's Office report.

Crews required protective suits because of the home's unsanitary conditions, Assistant Fire Chief Rick Helminski said.

"I was also advised that Barbara was so physically weak that bones in her body were breaking when EMS was attempting to carry her out of the house," the report read.

Ms. Foster was taken to the University of Toledo Medical Center, the former Medical College of Ohio hospital.

A hospital spokesman on Friday said no information was available for a patient by that name.

A bright orange sign posted in Ms. Foster's front window declared the home unfit for habitation Friday after Toledo-Lucas County Health Department officials assessed the dwelling.

Caution tape surrounded the property, and surgical-type face masks were discarded on the front lawn.

Sheriff's investigators believe Ms. Foster moved to the area from Arizona and had taught at Toledo Public Schools. They are not aware of any living relatives in the region, sheriff's Lt. Dave Carter said.

The Area Office on Aging had not had contact with Ms. Foster, but officials called her situation "extreme."

"The hope is not to have something get to this extreme. We don't want this to be the norm," said Pam Wilson, the agency's senior vice president of long-term care. "That's why we're here. We're here to link people up with help."

Ms. Wilson said the Toledo community is rich with resources and services for the elderly and disabled, and help is available to prevent situations from becoming emergencies. All it takes is a phone call to the agency's office or local law enforcement.

"To see somebody not be connected just kind of breaks your heart," she said.

Neighbors said they did not know Ms. Foster but recalled a volunteer from her church regularly stopping by her home. Robbie Zolciak said he believes Ms. Foster has lived next door to him since he and his wife bought their home about 10 years ago. He said he used to smile and wave to her when he mowed his lawn, but he never spoke to her.

"It's been years since I've physically seen her," Mr. Zolciak said.

A volunteer with Our Lady of Lourdes church, where Ms. Foster was also a member, told investigators he had delivered food to her home for the past 10 years. He said he was used to the smell but called 911 on Thursday because Ms. Foster was "not acting herself," according to the sheriff's office report.

He could not be reached for comment, and church officials did not return calls seeking comment Friday.

Ms. Foster's neighbors flocked to their front lawns Thursday evening to witness the commotion. It's a quiet neighborhood, Mr. Zolciak said, so the emergency lights were out of character.

"I've never seen so many people suited up," he said. "It was quite a scene."

Mr. Zolciak added the neighbors looked out for each other in terms of reporting possible vandals and speeding vehicles, but he was unaware Ms. Foster was in poor health.

Bill and Honey Malik have lived on the block since 1995 and said they didn't know Ms. Foster's name until this week.

"We didn't know her," Mr. Malik said. "I've never seen her at all."

Mrs. Malik said she saw her neighbor once years ago walking down her driveway with two canes. But the next time she saw Ms. Foster was on Thursday as medics moved her to an ambulance on a stretcher.

Detectives are now reviewing the case for any potential crime, Lieutenant Carter said. He declined to specify.

Ms. Foster was nearly $1,400 behind on her property taxes, according to county auditor records. She missed her first payment — $687 — in July, about the time she became confined to her chair.

Investigations of abuse and neglect on the elderly are handled by Adult Protective Services through Lucas County Job and Family Services.

Michelle Niedermier, JFS director, said state law prohibits the agency from confirming investigations of alleged neglect or abuse, including those that could have been the result of an elderly person's own actions.

She said about 12 cases of alleged abuse or neglect were referred to the office in 2016.

In 2006, Ms. Foster filed a complaint with the Lucas County Sheriff's Office against a woman she had allowed to live with her in return for assisting her with chores. Ms. Foster accused the woman of threatening to burn down her house if she didn't give her $3,000, court records show.
