33-year-old Mancel Wilson made an initial appearance Monday in Asotin County Superior Court on the charge. Police reports say Wilson was still married to Kay Zumwalt when he married his new wife, Lindsay Wilson.
In the report, Lindsay Wilson said she didn't know her new husband was already married until after she filed for divorce and Zumwalt called her. Mancel Wilson said he did not know that his divorce from his ex-wife was never finalized.
Bigamy is a felony carrying a sentence of up to one year in jail and a $10,000 fine.
Asotin County Prosecutor Ben Nichols said this is a very rare case, probably the first in his 15 years with the county.
Wilson will be back in court on April 20.
