GRAND CANYON NATIONAL PARK, Ariz. (AP) -- Grand Canyon authorities say they've hit a dead end in their search for a man who kicked a squirrel over the edge of the canyon.
A video posted online in late July that went viral shows a shirtless man with a straw cowboy hat lure the squirrel to the canyon's edge with food before kicking it into the air.
Grand Canyon Chief Ranger Bill Wright said Monday that none of the dozens of tips from people claiming to know the man have panned out. The Virginia man who filmed the incident says he doesn't know the man either.
Wright says the case will remain open pending further information.
An animal rights group has offered a trip to the Grand Canyon and $15,000 for information leading to an arrest and conviction.
