YELLOWSTONE, WY (AP) -- A second grizzly bear could be killed in connection with the fatal mauling of an Upper Michigan man at Yellowstone National Park last summer.

Park Superintendent Dan Wenk discussed the possibility on KODI-AM earlier this month. Park spokesman Al Nash said Tuesday that no date has been set for a decision.

One grizzly was euthanized last fall after it was linked to the scene of 59-year-old hiker John Wallace's death.  Wallace was from Chassell.

DNA tests show the bear killed a California hiker and also fed on Wallace, but officials aren't sure if the sow killed Wallace.

Hair from the second bear at issue was found about 22 yards away from where Wallace died, but test results didn't come back until after bears entered hibernation.

That bear, which has a radio collar, is still in its den.
