Investigators probe apparent serial dog killings in Lehigh Co.

UPDATE - Lehigh County humane investigators confirm puppies were in fact "skinned to the bone." Reward offered in the case. Read the latest from the Morning Call here.

Authorities believe a serial animal killer is behind multiple gruesome attacks in northeastern Pennsylvania.

The latest incident was reported Friday outside of Allentown where someone found a bag containing 11 dead puppies, all with their fur shaved by the side of the road, according to a report tonight on WFMZ-TV.

A week ago the body of what is believed to be an adult dog was found about 20 miles away in Lynn Township by the side of a road. It had been skinned and cooked. It's feet were cutoff and there was a rope around its right hind leg.

Investigators think both incidents are related, but they are not revealing any additional details such as the breed of the dogs or whether they were tortured while still alive.

Christine Wiggins, who works for the Lehigh County Humane Society, told the Morning Call of Allentown that a veterinarian took DNA samples of the adult animal and is going to send it to a lab to determine if it was a dog or wildlife. The animal, which weighed between 40 and 60 pounds, had been outside for at least four days, she said.
