A woman accused of shooting dead another woman over a dispute involving a political sign has been arrested by police in Washington State.

Angela Marie Conijn, 55, was booked into the county jail on second-degree murder charges after allegedly killing 32-year-old Kamran Cohee.

A magistrate's warrant was issued against Conijn yesterday, granting officers 30 days to file charges in the felony-level Skagit County Superior Court.
