WASHINGTON:  A pot-growing Kettle Falls family was acquitted on four of the five federal charges against them tonight in a case that was seen as a barometer for how conflicts between state and federal drug laws will be handled.

Rhonda Lee Firestack-Harvey, along with her son Roland Gregg and his wife, Michelle, each were convicted of one count of growing marijuana by a federal jury following a weeklong trail in U.S. District Court in Spokane. They were acquitted of conspiracy, trafficking and firearms-related charges but could still face prison terms of at least five years each on the production charge.
