wolf dies

HOUGHTON, MI (AP)--   Officials say a gray wolf captured in Minnesota for relocation to Isle Royale National Park has died. 

The National Park Service plans to move 20-30 wolves from the U.S. and Canadian mainlands to the Lake Superior wilderness park in the next few years to rebuild a once thriving population.

A 4-year-old female and a 5-year-old male were successfully flown there and released this week.
