Authorities say more than 40 dogs have been found living in "severely unsanitary and inhumane" conditions inside a Union County home.

County prosecutors said Wednesday that they plan to file multiple charges against 40-year-old Roselle resident Evelio Calderon. But the specific counts he'll face won't be determined until they review veterinarian reports.

Authorities went to Calderon's home last Thursday, along with health department workers and animal welfare groups. They say the dogs had been locked inside the home for an unknown amount of time and had to relieve themselves indoors.

They ranged in age from puppies to older dogs, varying widely in breed and size. Several were treated there for acute injuries that included open sores, malnourishment, joint problems and eye issues.

At least two of the dogs were suspected to be suffering from shock and were taken to a local veterinarian for emergency treatment.

The dogs are temporarily being housed in four different animal shelters across New Jersey.

It wasn't known Wednesday if Calderon has retained an attorney.
