The other animal seemed too big to be a fox but might have been sought for its pelt, humane society Officer Christine Wiggins said. Two pairs of thin latex gloves were found beside the animal and will be sent to a forensics lab.
Wiggins initially thought the two cases might be related, given that the animals were skinned.
Neighbors and friends are often reluctant to report animal cruelty, fearing retribution, animal welfare officials said.
"Someone usually knows but is afraid to come forward. Often there are multiple witnesses who maybe feel intimidated to not 'snitch,'" said Wendy A. Marano, spokeswoman for the Pennsylvania Society for the Prevention of Cruelty to Animals.
