BEMIDJI (AP) - The Minnesota Department of Natural Resources says the wolf suspected of attacking a teenager during a camping trip in northern Minnesota has tested negative for rabies.

The wolf that was tested was trapped and killed Monday at West Winnie Campground on Lake Winnibigoshish. Sixteen-year-old Noah Graham, of Solway, was camping with five friends last weekend when he was bitten in the back of his head, a wound which took 17 staples to close.

As of Tuesday, The DNR is waiting for DNA test results to confirm whether a wolf trapped and killed is the animal that attacked Graham.

Department of Natural Resources officials think it's the first documented serious-injury wolf attack on a human in Minnesota.

Meanwhile, the U.S. Forest Service has reopened the campground, which had been closed since Saturday.
