LEBANON TOWNSHIP, N.J. (CBSNewYork) – A New Jersey family says their trip to Canada turned into something from a horror movie.

Matthew and Elisa Rispolli went camping with their two sons at a national park in Alberta.

On August 9, they woke up to a wolf tearing through their tent. The animal clamped down on Matthew’s arm.

“I tried punching it twice with my left hand. I was trying to hit it closer to the neck,” he said. “It felt completely useless.”

“I grabbed his ankle or calf and felt him get pulled, and I pulled. I was just holding on for dear life,” Elisa added.

Another camper heard their screams and helped scare away the wolf. The animal was later tracked down and killed.
