BUTTE, Mont. -

Butte Police tell NBC Montana they found the body of a woman behind a Butte thrift store Sunday morning.

Undersheriff George Skuletich said it appears a woman was rummaging through a dumpster behind BSW Thrift Store on the east side of town, when she died of natural causes.

He said they sent the body to the State Crime Lab to see if alcohol or drugs were a factor in her death, and to make sure no foul play was involved.

The identity of the woman has not been released.
