A Pennsylvania mother has been sentenced for abandoning her children in a hazardous and unclean home while she traveled with her boyfriend.

According to court documents obtained by Law&Crime, 35-year-old Heidi Beer will serve a prison term ranging from three to 23 months.

Upon her release, Beer will be subject to three years of probation and, as reported by Pittsburgh’s ABC affiliate WTAE, she will also undergo six months of electronic monitoring in the very home that triggered the case.

Beer had previously admitted guilt to charges including endangering the welfare of children as a guardian, recklessly endangering another person, and submitting a false report.

Authorities arrested Beer and her 69-year-old mother, Leslie Ann Keller, on July 28, following a report of a domestic disturbance at a residence in Vandergrift Borough, Westmoreland County. However, the responding officers discovered conditions far worse than anticipated, according to Law&Crime’s earlier reports.

A noticeable smell wafted from the property, officers said, according to a criminal complaint reviewed by the regional outlet. And, once inside, investigators had to “avoid stepping on large feces droppings all over the residence, rotten food and urine pooled all over the floors.” Four children between ages 9 and 16 were said to have been inside, with the oldest telling police that their mother, Beer, had not been home in days.

The children reportedly had no water, and the shower spigot was broken off.

“It was very obvious that water had not been on in a long time,” the affidavit stated, adding that the children”s beds were observed to be deflated air mattresses, and there were holes in the ceiling across the home.

The question remained as to where exactly the children’s guardians were.

Beer had reportedly been staying with her boyfriend in Pittsburgh – about a 50-minute drive away – who had asked her to leave the kids behind because he could “give her a new and better life without them.”

But Beer was not the children’s only guardian, authorities maintained, reporting that their grandmother, Keller, lived about a mile away and was aware of the lack of food and water at the kids’ home. One of the children said Keller had not gone inside the home in months because it was “too gross,” and she allegedly admitted that the kids would fill up empty cat litter containers with water at her house because there was no water at theirs.

As officers led the grandmother through Beer’s filthy home, she reportedly tried to chastise the oldest child — a 16-year-old girl — for not cleaning up, until a responding officer in turn scolded the older woman, telling her it was not the “children’s responsibility to clean this absolute disgrace of a mess.”

Keller was also charged with endangering the welfare of children as a parent or guardian. She is awaiting a formal arraignment.
