Betsy Arakawa's death date revised to February 12

Authorities in New Mexico have revised the estimated date of Betsy Arakawa's death. New evidence shows she died on February 12, not February 11, as previously thought. Investigators found that Arakawa made three calls to a medical clinic on the morning of February 12. She reported feeling congested but did not attend her scheduled appointment later that day. The initial belief was that she died from a rare viral infection. The new information comes from analyzing her cellphone records.
