Addressing the confusion over Arakawa’s date of death, the sheriff’s office noted that they never officially reported it to be on Feb. 11; this was just the date of her last known activity. On Feb. 11, Arakawa is said to have exchanged emails with a massage therapist, visited a grocery store, pharmacy, and pet store, and returned home at around 5:15 p.m., according to data obtained from a garage clicker.
