MILWAUKIE, Ore. -- Directors with the Oregon Humane Society are offering a $500 reward for information that leads to an arrest in a disturbing and deadly case of animal abuse.

Spokesman Dave Lytle said that on March 28, a passerby in Milwaukie’s Scott Park discovered the body of a gray, domestic cat, strangled with a power cord.

Lytle said the remains were discovered, with the cord still around the animal's neck, near the park’s amphitheater.

The agency is pushing for felony charges, which is allowed under Oregon law.

“Torture is in the statute. Killing an animal is in the statute. That's a felony crime in Oregon,” said Lytle. “There's levels but this is the absolute highest for good reason because if you kill an animal that's the ultimate crime against that animal.”

News of the killing stunned staff and visitors alike at the Humane Society’s shelter in Northeast Portland.

“It's just really cruel,” said OHS visitor Heidi Church. “I wish I had that animal right now to keep it safe.”

Investigators say the domestic cat was a gray, long-haired female. She was 1 year old and was spayed, but had no collar or micro-chip.

They believe she was someone's pet.

Further, they worry if the abuser isn’t caught, he or she will strike again, possibly against people.

“We're very concerned about this perpetrator because there's a known link between violence against defenseless animals and violence against people,” said Lytle. “People who commit crimes against animals are likely commit crimes against their spouse, their children, even strangers.”

Anyone with information about the killing of the cat is urged to call the OHS tip line at (503) 802-6707.
