PORTAGE COUNTY, OH. (WEWS/CNN Newsource) - Agents are investigating after they found 146 dogs dead inside a home near Akron.

Piper's early life is something of a mystery. Mary Ellen adopted her from Canine Lifeline Incorporated, a business run by her Mantua neighbor. 

"I would like the border collie after all. And she was like, Ok come on out to Macedonia. And my friend said, Why do we have to go to Macedonia? She’s just across the street,” recounted Mary Ellen.

Mary Ellen, who asked that her last name not be shared, tells us her neighbor's property had become overgrown and neglected in recent years, though she had no idea the extent of that neglect.

"I feel like she was passionate about what she was doing, but she was way over her head,” said Mary Ellen.

Law enforcement executed a search warrant at the property Friday. The Portage Animal Protection League says a humane agent found 146 dead dogs in various stages of decay. No living dogs were found.

The APL said the homeowner is a co-founding operator of Canine Lifeline.

“I got the news story today that it was 146, it was gut-wrenching,” Mary Ellen said.

“According to statement on the organizations social media, the co-founder is also the subject of an animal neglect investigation in Parma. A number of dead and neglected dogs at a home there led investigators to this property in Portage County,” said reporter Catherine Ross.

JANICE ROBINSON WAS AT HER PARMA HOME SEVERAL WEEKS AGO WHEN HER NEIGHBOR WAS TAKEN AWAY BY AMBULANCE. SHE SAYS POLICE AND ANIMAL CONTROL SPENT MORE THAN 6 HOURS AT THE PROPERTY.

Then you see them bringing out all these cages with dogs in them and then bringing out all the animals that didn’t make it," remembered Robinson. "It was sad."

PUBLIC RECORDS SHOW THE SAME PERSON OWNS BOTH THE PARMA AND MANTUA PROPERTIES.

IN AN ONLINE STATEMENT, CANINE LIFELINE SAYS NO VOLUNTEERS WERE AWARE OF THEIR CO-FOUNDERS MEDICAL CONDITIONS, THE NUMBER OF DOGS SHE HAD OR THE CONDITION OF HER HOMES.

Representatives of Canine lifeline said, "LIKE THE GENERAL PUBLIC, VOLUNTEERS OF THE NON-PROFIT ANIMAL RESCUE ORGANIZATION CANINE LIFELINE HAVE BEEN SHOCKED, HORRIFIED AND CONFUSED TO LEARN OF THE DEVASTATING REVELATIONS." 

THE ORGANIZATION SAYS ITS COOPERATING WITH THE INVESTIGATIONS. MEANWHILE, NEIGHBORS WONDER WHY THERE WASN’T MORE ACCOUNTABILITY. 

There should be some legislation in place that any kind of rescue has someone come in and do an inspection,” said Mary ellen.

THE apl SAYS THE CASE IS STILL UNDER INVESTIGATION AND DECEASED ANIMALS WILL UNDERGO NECROPSIES TO DETERMINE THEIR CAUSE OF DEATH.
