(Selfridge, ND) — A woman is facing charges in a fire that destroyed the Selfridge Post Office last weekend. Melody Walker-White Twin has been federally charged with arson in last weekend’s fire at the post office. Investigators say several witnesses came forward and claim they saw Walker-White Twin throw cement blocks at the post office window and talked about burning it down. FBI agents say Walker-White Twin told them she threw rocks at the window and lit envelopes on fire in the entryway, but she didn’t think anything caught fire.
