Moyer's return to the Michigan copper district in the wake of the Jane-Dally murders marked his fifth trip to the Copper Country during the strike and his first since October. It would be his longest stay. Local newspapers printed names of "outside labor agitators" still within the district. As the grand jury started its work, Judge Orrin N. Hilton of Denver arrived to reinforce the WFM's legal staff. Moyer, one of the first witnesses before the jury, testified for two days. The jury got possession of the books and records of the Calumet WFM local, but the Ahmeek leaders, alike those over at South Range, claimed that their books had been sent to Denver.
