COHASSET, Mass. (AP) — A Massachusetts man already facing a charge of misleading investigators searching for his missing wife who has not been heard from since Jan. 1 now faces a murder charge in her disappearance. Norfolk District Attorney Michael Morrissey said Tuesday that Brian Walshe, who is being held on $500,000 bail after pleading not guilty to the misleading charge, will be arraigned on the more serious charge on Wednesday. Morrissey did not say what additional evidence led to the murder charge. A message was left with his attorney. Walshe’s wife, Ana Walshe, was last seen leaving their home in Cohasset south of Boston in the early morning hours of Jan. 1.
