Authorities are looking into a viral Internet video that shows a man kicking a squirrel off what appears to be the edge of the Grand Canyon.
But park officials say the chances of finding the man are slim.
"Right now they are working on it,'' park spokeswoman Kirby-Lynn Shedlowski said Monday. "They realize that it's been seen by a lot of people and that there's some sensitivity to treatment of wildlife.''
The short video posted on YouTube shows a shirtless, barefoot man in shorts and a straw cowboy hat leaving a trail of food at the edge of a canyon. He then puts on one of his shoes and kicks the squirrel into the air. Another similarly dressed man looks on.
Shedlowski said the geographical features in the video appear to match part of the Grand Canyon. Authorities have reached out to YouTube seeking more information, she said.
Messages sent Monday to the person who uploaded the video and to YouTube were not immediately returned.
