New Jersey is America's most densely populated state, but black bear sightings are not uncommon.
The state opened a five-day hunting season on the massive mammals last Monday, and 487 bears were killed during that time, according to the New York Times.
Wildlife authorities said that Pedals may have been killed, but they could not confirm the reports because he was never tagged.
"There are pictures of a bear with injured limbs that was brought into the station," Bob Considine, a spokesman for the Division of Fish and Wildlife, said.
Activists had previously raised US$22,000 to have Pedals moved to a wildlife sanctuary, out of fear that his condition would make it difficult to survive in the wild.
Lisa Rose-Rublack has said that money will now be used to "do some good in his memory."
