Humane Society says 13 puppies found dead in Ohio creek

FREMONT, Ohio -- A county Humane Society is investigating the deaths of 13 puppies found in a creek in northwest Ohio.

Animal cruelty investigator Adam Herrera says the puppies were likely pit bull mixes from the same litter. He says they were probably a month or two old. Herrera believes the pups were in the water several days before they were found.

The Humane Society of Sandusky County says the puppies were found just outside of Fremont on Saturday, by the property owner during a walk.

Herrera says it's difficult to tell whether the puppies were dead before they were put in the creek.

The organization is asking for the public's help in finding out who is responsible, and a reward is being offered.
